ABSTRACT:
Pneumatic means are synchronously coupled to an offset machine or the like in order to positively separate and pull down the bottom sheet in a stack. Movement of the pneumatic means is synchronized with the movement of a pivotal roller that advances the pulled-down sheet onto a conveyor belt for delivery of the sheet to the utilization device. The sheet being fed is automatically aligned in a lateral direction by movable guide means that are synchronized with the feeding of the sheet. The forward edges of the lower most sheets on the stack are separated by a flow of air.
