Abstract:
A loader of signatures or sheets (3) with scale-shaped arrangement to be deposited onto the plane (2â€²) of a bookbindery feeder (2), characterized in that it comprises a retractable plane (10) onto which a stack (7) of signatures or sheets (3) is deposited which lies at a minimum difference in height relative to the horizontal upper part (5) of a conveyer belt (5) for signatures or sheets (3) with scale-shaped arrangement, so that as a result the stack (7) on the retractable plane (10) is low, and which is located at a short distance from the plane (2â€²) of the feeder (2) and offset from the mechanisms (14) of the feeder (2) which is then downloaded onto the plane (2â€²) of the feeder (2) after the retractable plans (1) has moved back,and a level sensor (18) which detects the lack of a stack or the presence of a stack which is too low (21) on the plane (2â€²) of the feeder (2) and causes the retractable plane (10) to move into the path of the signatures or sheets (7) as they fall from the conveyor (5) so that a small stack (7) thereof will be loaded onto the retractable plane (10).
