Can for textile slivers

Abstract

 Can (10) for textile slivers which is suitable to feed spinning units included in spinning machines and to cooperate with automatic means for the distribution of the slivers within the can (10) and also with automatic devices for handling the can (10) itself and with automatic devices for the engagement and insertion of the slivers into the spinning units, the can (10) being able to have shapes and sizes employed in the textile industry for containing textile slivers and including on its upper edge (11) means (13-14-16-17) comprised to support and keep in a pre-set position the end of the textile sliver emerging from within the can (10) itself.

Description

[0001] This invention concerns a can to hold textile slivers. To be more exact, the invention concerns a can to hold textile slivers which comprises means suitable to support the end of the sliver and to keep it in a pre-set position.

[0002] The can of the invention may be of any shape and size and particularly, but not only, suitable to cooperate with automatic devices distributing slivers within the can and with automatic devices that engage the sliver and introduce it into spinning units.

[0003] The state of the art covers many types of cans employed to hold textile materials. These cans have a plurality of shapes and sizes.

[0004] In particular, the cans employed to hold slivers coming from drawing frames and intended to feed open-end spinning machines generally have a circular cross section with diameters varying according to the spacing between spinning units on the relative machine.

[0005] Cans are also known which have an elongate cross section or a section with two sides longer than the length of the other two sides; such a cross section can be rectangular, elliptic, oval or the like.

[0006] Cans with an elongate cross section are especially suitable to cooperate with automatic means that replace empty cans with full cans on spinning units since owing to their great content of sliver in a modest transverse volume they can feed the spinning units on their own without having recourse to the typical arrangement of circular cans in more than one row and can therefore be handled easily by the automatic replacement means.

[0007] The present applicant is not aware of any type of can which offers the features disclosed in this invention.

[0008] The can of this invention is disclosed in the main claim, while the dependent claims set forth various features of the invention.

[0009] The can to hold textile slivers according to the invention incorporates, substantially on its upper edge, at least one device to support and keep in a pre-set position the end of the sliver deposited in that can, the maintaining of that position taking place advantageously by lateral constraint.

[0010] This enables the end of the sliver to be available at once and accurately at the end of filling the can, or, at any rate, at the end of the depositing the sliver in the can, whether the can is being handled manually or, advantageously, automatically.

[0011] This device to support and keep in position the end of the sliver may be an integral part of the can or may be an assembly which can be fitted in a stable but independent manner to the can.

[0012] Where the cans have an elongate shape, the device will be included advantageously on at least one of the edges of the shorter sides of the can.

[0013] These and other special features of the invention will be made clearer in the description that follows.

[0014] The attached figures, which are given as a non- restrictive example, show the following:

Figs.1 show a can for textile slivers according to the invention;

Figs.2 show another form of embodiment of a can according to the invention;

Figs.3 show yet another form of embodiment of a can according to the invention;

Figs.4 too show a different form of embodiment of a can according to the invention.

[0015] In the figures the letter "a" alongside the number of the figure indicates a front view of a can, referenced generically with 10, according to the invention, whereas the letter "b" indicates a side view and the letter "c" indicates a view from above.

[0016] The figures show only cans 10 having an elongate shape, but the teachings of the invention can be applied also to any type of can 10 employed to hold textile slivers and, in particular, to cans having a circular cross section.

[0017] Figs.1 and 3 show cans 10 with a rectagular cross section, whereas Figs.2 and 4 show cans 10 having their short sides with a circular profile, which hereinafter we shall call "oval" for the sake of simplicity of description.

[0018] Obviously the specific teachings which can be inferred from Figs.1 and 3 can be applied also to Figs.2 and 4 and viceversa.

[0019] Likewise, the features of the embodiment included on one of the short sides of the elongate cans 10 can be applied in the same way to the other short side too and, in very special and exceptional cases, may also be included on the long sides.

[0020] In Figs.1 the can 10 is of a rectangular type and comprises on an upper edge 11 on the short sides 12 a device to support and position the end of the sliver deposited in the can 10. This device will keep in a pre-set position substantially by lateral constraint the end of the sliver emerging from the can 10 and hanging on the outside of the can 10 by a desired length.

[0021] In Figs.1 the device is a notch 13 machined in the upper edge 11 of the can 10; this notch 13 can be variously conformed, for instance with a rectangular or square profile 113, with a curved profile 213, with a V-shaped profile 313, or with yet other profiles.

[0022] Figs.2 show a can 10 of an oval type, on the short circular side 12 of which is a device 14 shaped like a spout and machined on the body of the can 10 so as to support and position the sliver.

[0023] The actual support 15 of the sliver on the edge 11 of the can 10 can be variously conformed, as shown for instance with profiles having a rectangular or square profile 115 or curved profile 215 in Fig.2a.

[0024] Figs.3 show an embodiment which comprises on the edge 11 a pair of projections pins 16 protruding from the can 10 and suitable to keep the end of the sliver between them.

[0025] Figs.4 show another embodiment like that of Figs.3, wherein the above projecting pins are elements which do not form part of the edge 11 but are separate elements, pins 17 in this case, solidly secured to the edge 11.

[0026] We have described here some embodiments of the invention, but it is obvious that a person skilled in this field can provide many more variants without departing thereby from the scope of the invention as claimed.
