Abstract:
1. A device for separating and discharging trimmings from a strip of material carried on a substantially rectilinear path, the strip comprising a thickness of continuous backing tape and a thickness of cutaway material comprising trimmings to be discarded and panels to be retained, the device comprising a rotating suction roll placed transversely to the path and tangential to the strip along an action line, and downstream of said action line on the one hand a device for collecting the panels situated substantially on said rectilinear path, and, on the other hand, a device for discharging the trimmings situated closer to the periphery of said roll, wherein the continuous backing passes through the device along said rectilinear path while permanently retaining on it the panels and in that the device comprises a device for temporary diversion of the strip, that can move at right angles to the strip, placed between said action line and said device for collecting the panels, in order to temporarily divert the path of the strip while bringing it closer to the roll, and as a result the initial stripping of the trimmings is made easier by the temporary diversion imposed by said diversion device, wherein the diversion device is segmented in order to act locally on the width of the strip depending on the shape of the trimming to be discharged.
