  • Patent number: 5318288
    Abstract: The invention relates to a method, apparatus and equipment for processing supple sheets comprising feeding a series of successive sheets (4) to a processing unit (23) by releasing them from the successive winding of a belt roll (3) and conveying them to the inlet side of said unit where they are processed and for collecting them at the outlet of said unit. The collection is carried out by the successive clamping of the sheets between the successive windings of a belt roll (13). The roll so formed is directly usable at the inlet of a subsequent processing unit by submitting it to a suitable translation combined or not with either a rotation around an axis (33) parallel to the shaft (16) of the belt roll or around an axis perpendicular to said shaft.
