Assembly for stream feeding sheets overlappingly staggered relative to one another via a feed table to an aligning device and for delivering the sheets aligned by the aligning device to a sheet-processing machine, the assembly maintaining movement of the sheets in direction towards the sheet-processing machine during alignment of the sheets by the aligning device, includes an aligning cylinder disposed under the feed table for receiving a sheet to be aligned which is fed thereto via the feed table, at least two rows of front lays disposed symmetrically on and around the circumference of the aligning cylinder, as well as a respective device disposed adjacent the rows of front lays for aligning side edges of the sheet, and a gripping device for holding the sheet until other further-transferring conveying device take over the sheet in-register.
Assembly for stream feeding sheets overlappingly staggered relative to one another via a feed table to an aligning device and for delivering the sheets aligned by the aligning device to a sheet-processing machine, the assembly continuously maintaining movement of the sheets in direction towards the sheet-processing machine during alignment of the sheets by the aligning device, comprising an aligning cylinder disposed under the feed table for receiving a sheet to be aligned which is fed thereto via the feed table, at least two rows of front lays disposed symmetrically on and around the circumference of said aligning cylinder, respective suction-pull bars likewise disposed on said aligning cylinder upstream of said rows of front lays as viewed in sheet travel direction, and drive means for said suction-pull bars disposed at one side on a side wall of the machine.
