Abstract (en)
[origin: EP0035428A1] 1. Device for feeding a processing machine with sheets, of the type comprising a flat and substantially horizontal feed board (4), a front stop (3), or "feed knife", making it possible to allow one sheet to pass through at a time, a rear push-rod (8) driven with a longitudinal reciprocating motion, and a rear stop (10) intended for supporting the rear of the stack of sheets (2) and placed above the said push-rod, characterized in that it also comprises one or more suction boxes (12) located in front and under the said feed table (4) and driven with a longitudinal reciprocating motion by means of a transmission (19, 20) linked to the transmission (21, 22), which moves the said push-rod (8), so that their strokes substantially match during at least a first part (c) of the forward stroke of the said push-rod, corresponding at least to the longitudinal distance (L) of support of the stack (2) by the said rear stop (11, 10), the said box or boxes (12) being connected to a device (13, 14) creating a partial vacuum therein during the said matching (c) of forward strokes, and then releasing the said partial vacuum.
