Maschine und Verfahren zum Stapeln

摘要

A stacking machine (10) with a cutter (24, 28) having a nip between two rollers and a continuous first conveyor belt (38) against an under surface of a lower run (46) of which bundles of web material cut to length by the cutter are conveyed to a first or a second stacking station (18, 20). A second adjacent toothed conveyor belt (50) passing round toothed rollers (52, 54) has spaced clamp arms (58) connected thereto which move with the first conveyor belt and hold the bundles against the first conveyor belt until the bundles are restrained either by a retractable stop actuated by an air cylinder (124) at the first stacking station (18) or by a fixed stop (116) at the second stacking station (20) where they fall onto vertically displaceable vibrating plates (90) from which a stack of bundles is periodically displaced by fingers (104) extending through the plate onto an adjacent take-away conveyor equipped with pusher fingers (138).
