ABSTRACT:
A process for gripping flexible layers arranged in a stack of layers in order to separate one or more upper layers from the other layers of the stack makes use of a needle (23) moving with respect to a contact surface (14a) with a clearance (16). The motion of the needle (23) is implemented in such a manner that during the displacement of its end, said needle thrusts the upper flexible layer toward the clearance (16) to form a corrugation in said clearance; during the final stage of the motion, the needle crosses said corrugation.
