<description id="desc" lang="en">
<p id="p0001" num="0001">The present invention relates to an automatic machine for the processing of corrugated paper in order to obtain containers according to the preamble of claim 1. Such machines are generally known.</p>
<p id="p0002" num="0002">Currently, the need to place the various industrial products in suitable containers forces the individual companies, due to the plurality of items produced thereby which differ in dimensions, to resort to large stocks of containers in various sizes.</p>
<p id="p0003" num="0003">The machines currently known for providing said containers allow the manufacturing of a single product, or more than one but with features which are very similar to each other in dimensions and type of stiffening or reinforcement.</p>
<p id="p0004" num="0004">The main aim of the present invention is therefore to eliminate the disadvantages described above in known types by devising an automatic machine which allows to obtain containers in corrugated cardboard which are provided, according to the specific requirements, with the required dimensions and the desired stiffenings and reinforcements.</p>
<p id="p0005" num="0005">Within the scope of the above described aim, a further important object is to devise a machine which associates to the previous characteristics that of being provided with high flexibility in use, allowing, at the same time, to obtain a product which can be stored optimally.</p>
<p id="p0006" num="0006">Another object is to provide a machine which allows to obtain, in sequence, containers having even different dimensions and characteristics from one to the next.</p>
<p id="p0007" num="0007">The aim and the objects mentioned above and others which will become apparent hereinafter, are achieved by an automatic machine for the processing of corrugated paper, characterized in claim 1.<!-- EPO <DP n="2"> --></p>
<p id="p0008" num="0008">Further characteristics and advantages of the invention will become apparent from the detailed description of a particular, but not exclusive, embodiment, illustrated only by way of non-limitative example in the accompanying drawing tables, wherein:

</ul></p>
<p id="p0009" num="0009">With reference to the above described figures, the machine 1 is composed of a first station 2 for the multiple feed of corrugated paper or cardboard 3.</p>
<p id="p0010" num="0010">In the particular embodiment chosen, rolls of cardboard have been positioned at the station 2, which comprises a supporting frame 4 to the side members of which the shafts 5 of three rolls, indicated with the reference numerals 6a, 6b and 6c, are freely pivoted.<!-- EPO <DP n="4"> --></p>
<p id="p0011" num="0011">Each roll may be composed of corrugated cardboard having a different width and/or different length.</p>
<p id="p0012" num="0012">Preferably, the cardboard of the rolls 6a and 6b is unrolled by making it slide on free rollers 7a and 7b arranged below and transversely with respect to the frame 4.</p>
<p id="p0013" num="0013">The axes of said rollers lie in planes arranged parallel to each other, between the same and the ground there being provided separation rods indicated with the reference numerals 8 and 9.</p>
<p id="p0014" num="0014">In order to prevent the inertia imparted during the unrolling of the cardboard from excessively unrolling the rolls, a brake 10 is associated to one of the ends of the shafts 5.</p>
<p id="p0015" num="0015">Said brake is composed of two identical jaws 11a and 11b arranged diametrically with respect to the shaft 5 and placed on a plane which is perpendicular thereto.</p>
<p id="p0016" num="0016">Each jaw is provided with a throat, arranged concentrically with respect to the shaft 5, to which a rubber crown 12 is rigidly coupled; the two jaws are mutually associated to each other by means of screws 13 concentrically to which springs 14 are arranged which interact with the facing surfaces of the jaws.</p>
<p id="p0017" num="0017">The lower jaw 11a, rotating together with the shaft 5 during the unrolling, interacts with a pin 15 which projects from the frame 4.</p>
<p id="p0018" num="0018">Said pin, which is provided with an axis parallel to the one of the shaft, thus allows the brake 10 to always keep the corrugated cardboard 3 at the optimum tension.</p>
<p id="p0019" num="0019">The shaft 5 is indeed gripped vice-like during the interaction with said pin.<!-- EPO <DP n="5"> --></p>
<p id="p0020" num="0020">The station 2 can be composed of a plurality of frames 4 joined to each other so as to allow the use of cardboard rolls having different characteristics.</p>
<p id="p0021" num="0021">Consecutively to the station 2, the second station 16, for the insertion of the cardboard, is provided, composed of a supporting frame 17 which supports a lifting assembly 18.</p>
<p id="p0022" num="0022">The frame 17 is provided with two rectangular lateral shoulders 19, provided, on the side arranged proximate to the first station, with a pair of free transverse rollers 20a and 20b, the axes of which are arranged on the same plane as those of the rollers 7a and 7b.</p>
<p id="p0023" num="0023">Three more free transverse rollers 21a, 21b, and 21c, with the axes arranged on the same plane perpendicular to the one of the axes of the pair 20a and 20b, allow the feed of the corrugated cardboard 3 on parallel planes within the station 16.</p>
<p id="p0024" num="0024">The roller 21c takes up the cardboard directly from the roll 6c, as illustrated in Fig. 2.</p>
<p id="p0025" num="0025">The lifting assembly 18 is composed of two identical rectangular lateral plates 22a and 22b, transversely to which three pairs of rollers are pivoted, each being indicated with the reference numeral 23, the axes of which, parallel to each other, are arranged on the same plane, perpendicular to the base or rest plane of the station.</p>
<p id="p0026" num="0026">Each pair of rollers 23 is composed of a motorized roller 24, driven by a suitable motor 25, and of a free counter-roller 26, the axis 27 of which is associated, at each end, to a slot 28 with à vertical axis formed on the plates 22a and 22b.<!-- EPO <DP n="6"> --></p>
<p id="p0027" num="0027">Each end of the axis 27 is furthermore engaged in a groove 29 provided on the stem of a swinging element 30, which is essentially Y-shaped, and freely pivoted to the plates 22a and 22b at the terminal end of the stem facing opposite to the station 2.</p>
<p id="p0028" num="0028">Between the flaps of each element 30, a shaft 31 is provided, mounted on an eccentric element 32, which can be operated by means of a lever 33.</p>
<p id="p0029" num="0029">The rotation of the lever 33, as illustrated in Fig. 5, causes the element 30 to rotate with respect to its pivot axis, thus raising or lowering the flaps of said element 30.</p>
<p id="p0030" num="0030">At the same time, the axis 27 of the counter-roller 26 is raised or lowered, thus allowing its uncoupling-coupling with the motorized roller 24.</p>
<p id="p0031" num="0031">This allows the manual insertion of the corrugated cardboard 3 in the initial phase or during the eventual roller replacement phase.</p>
<p id="p0032" num="0032">Fig. 18 illustrates another aspect of the invention, in which two eccentric elements, indicated with the reference numerals 114 and 115, are associated to the end of the axis 27 of the free counter-roller 26, which eccentric elements are rotatably associated with the lateral plates 22a and 22b.</p>
<p id="p0033" num="0033">The angular position of the eccentric element 115 can be varied by means of the lever 33, it being possible to fix said lever, by means of a suitable locking element interposed between said lever and the plate 22a, in a preset position.</p>
<p id="p0034" num="0034">This allows one to preset the interspace between the motorized roller 24 and the counter-roller 26.<!-- EPO <DP n="7"> --></p>
<p id="p0035" num="0035">The vertical motion of the lifting assembly 18 is imparted by means of a pair of chains 34, each of which is provided with its ends associated to the upper and lower ones of one of the plates 22a and 22b.</p>
<p id="p0036" num="0036">On the upper and lower crosspieces of the shoulders 19, two toothed wheels are provided, indicated with the reference numerals 35a and 35b: the first wheel 35a is keyed on the axis of a motor and reducer assembly 36, while the second wheel 35b is freely rotatable.</p>
<p id="p0037" num="0037">The motion along a vertical axis, perpendicular to the base of the station, is instead allowed by the presence of a pair of driving shafts 37, arranged vertically between the upper and lower crosspieces of the shoulders 19 proximate to the beam facing towards the third station 38.</p>
<p id="p0038" num="0038">The coupling between the shafts 37 and the plates 22a 22b occurs by means of a wheel 39a and a pulley 39b freely pivoted onto a pair of tabs 40 which protrude from the plates.</p>
<p id="p0039" num="0039">At the end of the plates 22a and 22b where the cardboard feed occurs, proximate to each of the pairs of rollers 23, oscillable bars 41, slideable on crosspieces 42, are provided, suitable for allowing the exact centering of the cardboard with respect to the middle longitudinal axis of the machine 1, which axis may be indicated hereinafter as the operating axis.</p>
<p id="p0040" num="0040">This centering is facilitated, since the beams of the shoulders 19 are sufficiently mutually spaced apart.</p>
<p id="p0041" num="0041">Downstream of each pair of rollers 23, combs 43 are provided which are adapted for facilitating the insertion of the cardboard selected among the three available by the<!-- EPO <DP n="8"> --> lifting assembly 18.</p>
<p id="p0042" num="0042">Figures 19 and 20 illustrate an aspect of the invention which is adapted for maintaining the cardboard straight in case the cardboard is uneven in its dimensions due, e.g., to thermal changes it has been subject to. This is obtained by providing the adjustment of the position of the lifting assembly 18 by rigidly coupling to the plate 22b a pair of U-shaped tabs 40, and closed at the free end by an abutment 116. Inside each of said tabs, sliders 117 are slideable and accommodatable, and the wheel 39a and the pulley 39b are pivoted thereto and interact with the shaft 37.</p>
<p id="p0043" num="0043">Said sliders 117 are rigidly mutually interconnected by means of a beam 118. The terminal end of the stem 119 of a piston 120, connected to the plate 22b, is associated proximate to the middle portion of said beam.</p>
<p id="p0044" num="0044">Should the cardboard thus have a certain conicity, the operation of the piston 120 allows the angular motion of the entire lifting assembly 18 with respect to the plane of arrangement of the shafts 37, fixed to the shoulders 19, until it straightens and thus allows to center the cardboard for subsequent processing.</p>
<p id="p0045" num="0045">The cutting station 38 is composed of a cutter assembly which comprises a supporting frame 44, pivoted to a transverse guiding rail 45 and moved by means of a chain 46 operated by a suitable motor and reducer assembly 47.</p>
<p id="p0046" num="0046">The frame 44 accommodates a tempered rotating blade 48, arranged on a plane which is transverse with respect to the machine 1; the blade is of the self-sharpening type, since it cooperates with a replaceable fixed abutment blade 49, above which the cardboard is pushed by means of the roller<!-- EPO <DP n="9"> --> 24.</p>
<p id="p0047" num="0047">The blade 48 is freely pivoted on a small shaft 50, which is connected to the frame 44; a spring 51, coaxial to the small shaft, allows a regular motion of the blade 48 and an adequate pressure on the fixed abutment blade 49. A cylinder with trapezoidal cross section 52 is arranged to the side of the latter, which cylinder interacts, during the transverse motion of the frame 44, with the ends of a metal strap 53 tilted towards the cardboard feed region and, at the other end, pivoted to a transverse axis. The blade 48 is fixed coaxially with respect to the cylinder 52.</p>
<p id="p0048" num="0048">The strap thus blocks the corrugated cardboard in the cutting phase, preventing the formation of burr.</p>
<p id="p0049" num="0049">At least one elastically deformable element 54 is associable with the strap, for adjusting the inclination thereof; accordingly, the blade 48 can also assume a desired angle with respect to the fixed blade 49.</p>
<p id="p0050" num="0050">This, together with the fact that the frame 44 can swing slightly with respect to the axis 45, renders the blade 48 self-sharpening, and facilitating cutting at the same time.</p>
<p id="p0051" num="0051">In order to prevent said blade 48 from leaving the cutting seat in any way, a biasing bar 55 is provided above the frame 44, which bar interacts with a connecting rod 56 by means of a bearing 57 freely pivoted thereto.</p>
<p id="p0052" num="0052">Said connecting rod is in turn freely pivoted, at one end, to the frame 44; between the other end and said frame, a cylindrical helical compression spring 58 is instead interposed.</p>
<p id="p0053" num="0053">It should be observed that it is possible to extract,<!-- EPO <DP n="10"> --> to the side of one shoulder 19, the entire cutting assembly, thus allowing maintenance and/or the eventual replacement of the rotating blade 48 and coaxial cylinder 52.</p>
<p id="p0054" num="0054">In order to gain access to the abutment blade 49, instead, it is sufficient to raise the strap 53.</p>
<p id="p0055" num="0055">Consecutively to the station 38, a fourth station 59 follows for the scoring of the corrugated cardboard.</p>
<p id="p0056" num="0056">In the particular embodiment chosen, said station is composed of three pairs of scorers, each scorer of the three pairs being indicated with the reference numerals 60a, 60b and 60c.</p>
<p id="p0057" num="0057">Each scorer of each pair is pivoted on a transverse shaft 61 and is associated to a fork 62, upwardly provided with a cylindrical guide 63 which is slideable on a transverse shaft 64, which is fixed and parallel to the previous one.</p>
<p id="p0058" num="0058">Each scorer of each pair can furthermore be positioned symmetrically with respect to the operating axis of the machine 1 by means of a suitable worm screw 65.</p>
<p id="p0059" num="0059">Said worm screw is arranged transversely with respect to the station along an axis which is parallel to the one of the shafts 61 and 64 and is associated to the fork 62 by means of a bush 66.</p>
<p id="p0060" num="0060">As indicated in Figure 11, a locking ring 67, associable to the bush 66, allows the manual adjustment of the initial position of each scorer, so that each pair of scorers is arranged symmetrically with respect to the operating axis of the machine.</p>
<p id="p0061" num="0061">The motion of each pair of scorers along the transverse axis is allowed by the fact that each worm screw 65 is<!-- EPO <DP n="11"> --> motorized with its own motor and reducer assembly 68.</p>
<p id="p0062" num="0062">In order to allow movements in opposite directions from a one-way rotation of the worm screw 65, said worm screw has formed thereon half a left-handed thread and half a right-handed thread.</p>
<p id="p0063" num="0063">Each scorer interacts with a roller 69, placed below and provided with an axis parallel to the one of the small shaft 61, allowing to perform the longitudinal scoring of the cardboard.</p>
<p id="p0064" num="0064">Advantageously, the ends of said roller 69 are mounted on eccentric elements so as to permit adjustment of its parallelism with respect to the shaft 61 to thus allow the optimum scoring of the corrugated cardboard 3.</p>
<p id="p0065" num="0065">A single motor 70, instead, controls the rotation of the shaft 61 of the scorer 60c and therefore, by means of suitable transmissions constituted by toothed wheels 71 interacting with matchingly toothed wheels keyed to one end of the shafts 61 of the scorers 60a, 60b and 60c, the advancement of the corrugated cardboard 3.</p>
<p id="p0066" num="0066">Subsequently to the station 59, the fifth station is provided for the punching or dinking of said cardboard.</p>
<p id="p0067" num="0067">As illustrated in Figs. 12, 13 and 14, the fifth station is composed of two dinking bodies 72a and 72b which comprise a box-like supporting frame 73a and 73b, pivoted laterally to a transverse guiding rail 74.</p>
<p id="p0068" num="0068">The end of a same chain 75 is associated with each frame, which chain is transmitted, at the extreme sides of the machine, by two identical toothed wheels 76, of which one is freely rotating and the other is keyed on the axis of a motor and reducer assembly 77.<!-- EPO <DP n="12"> --></p>
<p id="p0069" num="0069">The two dinking bodies operate by moving simultaneously towards the operating axis of the machine 1: indeed, the chain 75 is associated, in the upper part, to the frame 73a of the right-hand punching body 72a (Fig. 13) and, in the lower part, to the frame 73b of the left-hand punching body 72b (Fig. 12).</p>
<p id="p0070" num="0070">Each frame 73a and 73b accommodates a pair of identical, mutually counterposed rotating blades 78, which are furthermore mutually blocked between two disks 79a and 79b to ensure their parallelism.</p>
<p id="p0071" num="0071">Said blades, are mounted on the same small shaft 80 arranged transversely with respect to the frame, are allowed an axial clearance, and are spaced from the inner surfaces of the frame.</p>
<p id="p0072" num="0072">Coaxially to the small shaft, a cylindrical helical spring 81 is arranged interposed between the inner surfaces of the disks.</p>
<p id="p0073" num="0073">A cylinder with a trapezoidal cross section 82 is coaxially associated to the disk 79a and interacts, during the transverse motion of the dinking body, with the end of a transverse metal strap 83 tilted towards the side where the cardboard 3 is fed, and associated at the other end to an axis arranged transversely with respect to the machine.</p>
<p id="p0074" num="0074">Said strap thus blocks, similarly to what occurred for the cutter assembly, the corrugated cardboard 3 during the dinking.</p>
<p id="p0075" num="0075">The dinking body furthermore comprises two fixed abutment blades 84a and 84b, arranged on the plane of the cardboard, replaceable and arranged mutually parallel with such an interspace as to allow the passage of the blades 78,<!-- EPO <DP n="13"> --> and having moreover such a shape as to make the latter self-sharpening.</p>
<p id="p0076" num="0076">Again similarly to the cutter assembly, at least one elastically deformable means 85 is associable with the strap 83, between the two ends, which means adjusts the inclination of the blades 78, since the frame 73a and 73b can swing slightly with respect to the guiding bar 74.</p>
<p id="p0077" num="0077">Again similarly to the cutter assembly, each frame 73a and 73b is upwardly provided with a connecting rod 86 interacting, by means of a bearing 87 pivoted freely thereto proximate to the middle portion, with a biasing bar 88.</p>
<p id="p0078" num="0078">The connecting rod is freely pivoted, at one end, to the frame of the dinking body, between the other end and said frame there being interposed a cylindrical helical spring 89.</p>
<p id="p0079" num="0079">Also in this case, each dinking body can be moved out of the lateral shoulders 90 of the station in order to perform operations.</p>
<p id="p0080" num="0080">The ends of the chain 75 are associated with the frames 73a and 73b so that their position can be adjusted until it is symmetrical with respect to the operating axis of the machine.</p>
<p id="p0081" num="0081">In order to allow each dinking body to perform the required path, and therefore to punch the cardboard correctly, each frame 73a and 73b is provided with a mechanical stroke limit at the location of a blade which is fixed to and projects from the pair of scorers 60c, which is closest to the operating axis of the machine.</p>
<p id="p0082" num="0082">Each dinking body is furthermore provided with means adapted for the removal of the strip of cardboard obtained<!-- EPO <DP n="14"> --> during the dinking.</p>
<p id="p0083" num="0083">Said means, illustrated in Fig. 13, comprises a magnet 91, associated to the frame to the rear of the work area of the blades, which magnet controls the motion, along a vertical axis, of a small bar 92 to which an arm 93 is downwardly freely pivoted and is angled and arranged on a plane passing through the connecting plane of the pair of blades 78.</p>
<p id="p0084" num="0084">One end of said arm 93, adjacent to the pivoting point of the small bar 92, is in turn freely pivoted to the frame whilst at the other end of the arm 93, underlying the pair of blades 78, there is associated a blade 94, facing towards the direction of said blades 78.</p>
<p id="p0085" num="0085">When the magnet is not activated, the end of the blade 94 is arranged on a plane which is lower than the rest plane of the cardboard: when the magnet is activated, the small bar 92 is drawn upwards, raising the arm 93 and thus causing the blade 94 cut the terminal end of the cardboard strip.</p>
<p id="p0086" num="0086">A suitable switch keeps the magnet activated for a fraction of a second while the punching body is returned to a position proximate to the walls 90: this allows the tearing off of the cardboard strip if it has not been cut off previously.</p>
<p id="p0087" num="0087">The sixth station is provided at the outlet of the fifth station, which sixth station comprises a pair of transverse rollers 95a and 95b adapted for ensuring the outgoing entrainment of the cardboard, as well as the off-cuts or punchings. In this case, the motion occurs by means of a toothed belt 96 trained around toothed wheels 97a and 97b; the first wheel takes up the motion from the roller 69<!-- EPO <DP n="15"> --> and the second one transmits it to a roller 97c which moves the roller 95a which transmits the motion to the 95b, via the belf 96.</p>
<p id="p0088" num="0088">This solution has been adopted to allow the optimum adjustment of the parallelism between the rollers 95a and 95b according to the thickness of the cardboard.</p>
<p id="p0089" num="0089">After said rollers, a motorized set of rollers 98 is provided for the transport, the glueing and the folding of the flaps of the cardboard obtained by scoring.</p>
<p id="p0090" num="0090">Said functions are obtainable by means of glue dispensers 99 and L-shaped swinging arms 100 hinged at the end of the shortest part.</p>
<p id="p0091" num="0091">Both dispensers and arms may be moved transversely with respect to the set of rollers, and provided with a bush 101 interacting with a worm screw 102.</p>
<p id="p0092" num="0092">The worm screw is operated by a single motor 103: the symmetry of the pairs of dispensers and arms with respect to the operating axis of the machine is allowed by virtue of the fact that the worm screws 102 are provided along half of their length with right-handed thread and along the other half of their length with a left-handed thread.</p>
<p id="p0093" num="0093">The machine 1 finally comprises a means 104 for control and data input for the programing, command and control of the operating phases.</p>
<p id="p0094" num="0094">Said means is constituted by a central logic unit contained within a box-like structure 105.</p>
<p id="p0095" num="0095">The data can be input by means of a keyboard 106 and can be displayed on a monitor 107 or a printer 108 may be provided for printing the cardboard.</p>
<p id="p0096" num="0096">A button panel 109 finally allows manual intervention<!-- EPO <DP n="16"> --> in case of malfunction, as well as the verification, by means of suitable optical indicators, of the functionality of the various components.</p>
<p id="p0097" num="0097">The machine 1 is furthermore provided with sensors and actuators so as to allow the control means 104 to command and control the various processing phases.</p>
<p id="p0098" num="0098">The use of the machine 1 initially entails the positioning of the corrugated cardboard 3 of each roller 6a, 6b and 6c, each proximate to a pair of rollers 23.</p>
<p id="p0099" num="0099">This positioning is facilitated by the presence of the eccentric element 32 which allows the lifting of the counter-roller 26 when inserting the cardboard.</p>
<p id="p0100" num="0100">The oscillable or swinging bars 41 furthermore allow the exact centering of the cardboard with respect to the operating axis of the machine, said axis being the reference axis for the control means 104.</p>
<p id="p0101" num="0101">Subsequently, the control means 104 will command the actuation of the motor and reducer assembly 36, which positions the lifting assembly 18 so that the desired cardboard is positioned at the working plane of the third station 38.</p>
<p id="p0102" num="0102">In the case illustrated in Fig. 5, this is the cardboard of the roll 6b.</p>
<p id="p0103" num="0103">Entrained by the rollers 24, the cardboard may be initially trimmed by the cutter assembly and then introduced into the fourth station.</p>
<p id="p0104" num="0104">Meanwhile, the control means 104 will have positioned the scorers 60a, 60b and 60c in the required positions, so as to perform the required scorers or creases.</p>
<p id="p0105" num="0105">After passing beyond the last scorer 60c, the cardboard<!-- EPO <DP n="17"> --> will enter in the fifth station, where the two dinking bodies 72a and 72b will perform the dinking of the cardboard, removing at the same time the strip of punched-off cardboard.</p>
<p id="p0106" num="0106">Meanwhile, the control means 104 will have activated the cutter assembly of the third station 38, which will cut the cardboard once it reaches the required length.</p>
<p id="p0107" num="0107">Should it be required to perform trailing dinkings, the cutting of the cardboard is ensured in any case by the presence of the pair of rollers 95a and 95b of the sixth station.</p>
<p id="p0108" num="0108">In the sixth station the last phase of the processing occurs, which entails the eventual glueing of the flaps of the cardboard and their folding.</p>
<p id="p0109" num="0109">It has thus been observed that the invention achieves the intended aim and objects, an automatic machine being provided which allows one to obtain cardboard which is punched and scored or creased so as to obtain a container having the desired dimensions and reinforcements.</p>
<p id="p0110" num="0110">Since it is furthermore possible to preselect the cardboard of the required dimensions, the machine allows remarkable flexibility in use, it being possible to provide punched and scored cardboards for the obtainment of containers of any dimensions.</p>
<p id="p0111" num="0111">Naturally, the invention thus conceived is susceptible to numerous modifications and variations, all of which are within the scope of the same inventive concept.</p>
<p id="p0112" num="0112">Thus, as an example, one of the three scoring assemblies 60a, 60b and 60c may be replaced by a cutter assembly for the longitudinal cutting of the cardboard.<!-- EPO <DP n="18"> --></p>
<p id="p0113" num="0113">Similarly, an assembly-for the transverse scoring of the cardboard may be provided, positioned, for example, after the station 38.</p>
<p id="p0114" num="0114">Regarding the type of cardboard used, it may also be constituted by sheets of corrugated paper, by pleated cardboard, or by similar material with which a box may be produced. Fig. 17 illustrates the use of an oscillably mounted container 110 which contains glue 111 which is applied to the cardboard 3 by means of one or more brushes 112 connected to an outflow duct.</p>
<p id="p0115" num="0115">The container can be refilled, is pivoted between two beams which constitute the frame 4, and its angle with respect to the plane of the underlying cardboard can be adjusted by means of a suitable screw 113 protruding, below the pivoting point of the container, from the beam of the frame.</p>
<p id="p0116" num="0116">Said container allows, e.g., to stably and mutually associate two sheets of corrugated cardboard unrolled from two contiguous rollers so that they are associated with counterposed corrugations.</p>
<p id="p0117" num="0117">Naturally the processed cardboard may have any dimensions and thickness, and it may be obtained by superimposing a plurality of individual sheets.</p>
<p id="p0118" num="0118">Naturally, the materials and the dimensions of each individual component of the machine may be any according to requirements.</p>
<p id="p0119" num="0119">Also, all of the individual components may be replaced with technically equivalent elements.</p>
