Abstract: A frame is mounted on driven base rollers for rotatable movement from a horizontal to a vertical position. A platen plate is movable on the frame with respect to a platen plate fixed to the frame to clasp a stack of sheets therebetween. An air table is located behind the platen plates and has a perforated surface, the perforations of which may be selectively obscured. An air blower is driven by a variable speed motor to selectably introduce a flow of air into the air table and through the air table perforations into a stack of sheets clamped by the platen plates. A controller may be remotely positioned from the motor and allows variable control of the air flow quantity through the clamped stack to appropriately aerate a wide variety of sheet materials under varying atmospheric conditions.

Abstract: A movable cart has an air deck with a gripper assembly mounted thereon which has two opposed gripper arms which may be extended into a jogger/aerator to engage and grip a stack of paper supported on an air deck therein and to withdraw the stack fully onto the cart. The cart is movable between the jogger/aerator and one or more sheet feeding apparatus. Each sheet-feeding apparatus is outfitted with an air deck onto which the loaded sheet stack may be automatically unloaded. A transfer deck has a plurality of swords with spring-loaded dogs for storing a stack of paper and advancing the stored stack into the sheet-feeding apparatus upon exhaustion of its sheet supply.
