[0001] The invention 'refers to a machine which, with a continuous cycle, penni- ts to obtain
parallel furrows on panels, operating by pressure effect on ly. A nex design procedure
allows a particular employ in the prefabricated building and arrangements in general.
Conventionally panels are produced resulting from assembling of plates on woody fibrous
base with PVC film or resinous paper sheet.
[0002] At present, in order to obtain a depth ornamental effect, parallel furiro ws are
obtained by passing the panel under a battery of milling disks. This system casuses
two inconveniences: it interrupts the structure continuity on the visualization plane
and weakens it on account of the material removal. These inconveniences turn out particularly
heavy if we consider that these panels are made in extremely small thickness.
[0003] The invented device.permits the integral solution of these problems. A machine is
employed with base casting on the ground bearing a travelling plane for passing the
panel under a device for making parallel furrows. This is foreseen on a pair of columns
with coaxial disposition to allow a lowering to be regulated in order to bring a frame
in a transversal position and bringing the pressure furrowing assembly in operating
position. The device employ a shaft with parallel threading for setting a bat tery
of pressing disks at distances to be preset. By means of a crank operating on a cardan
system, the movement is transmitted in a synchrony sm with the two coaxial devices.
The motor assembly is then started that contemporarily moves a pair of input rollers
on the travelling plane, as well as another output pair, and centrally a roller to
locate the said furrowing group which, by means of the corresponding battery of pulleys
brought on the shaft, strarts a corresponding battery on inking means. Inking is earried
out by tranemission from the relevent ink Helders, by means of rollers, pen and inking
device, on the furrowing disks.
[0004] A not limiting execution form is illustrated in the drawings of Tables 1 and 2, where
Fig. 1 is the side perspective view of the machine seen from the outlet side, with
a section view of the outgetting panel. The frame can be noted, which is supported
on coaxial means and with control led lowering by means of a hand crank, as well as
the furrowing assembly brought in middle location by a positioning frame. A system
of pulleys is to be seen too, which drives a battery of inking means transmit ting
on the pressure rollers. Fig. 2 is the front view of the feft outlet part of the machine;
the system for the furrowing device stabilization will be noted. Fig. 3 is a particular
of the travelling plane on the right input side. The furrowing articolated initial
part, with the inking device, and the input roller can be noted. Fig. 4 is the longitudinal
section of the machine showing the motion compartments.
[0005] The machine foresees the panel mechanical travel on plane 1 by means of roller 2,
which has below the location roller 3. The operation is carried out by pressure while
the panel is passing between the lower location rol ler 4 and the above pressure compartment
consisting of a parallel disk group 5. These disks perform the two tasks of furrowing
by means of squε ezing, as well as of inking in the relevant cavities. The pressure
disks 5 are supported on a frame with vertical translation on a pair of side coaxial
devices 6 and 7: these ones, through crank 8 and with a transmit sion cardan system
9, with contemporary effect, lower frame 10 supporting shaft 11 and ball bearing with
pressing battery 5 fitted on. For stabilizing the. furrowing device, an intermediate
connection between the frame transversal profile piece 12 and shaft 11 has been foreseen.
Plate 13 equipped with ball bearing 14 is employed for rotating shaft 11 and suppor
5. These disks perform the two tasks of furrowing by means of squeezing, as well as
of inking in the relevant cavities.
