ABSTRACT:
An apparatus for inserting chipboard or cardboard spacers within a lapstream of paper sheets exiting a press on a lapstream conveyor includes a chipboard ejector for firing chipboards toward the lapstream conveyor in a direction which is opposite that of the conveyor. A plurality of vacuum feet are positioned over the conveyor and are responsive to a control pulse issued by a programmable counter to pick up the leading edge of selected sheets in the lapstream. Simultaneously, the chipboard ejector fires a chipboard, in response to another control pulse from the counter, toward the point on the conveyor over which the sheet is being picked up. The vacuum feet are then released, dropping the selected paper sheet and the chipboards are thus reliably inserted at regular intervals within the lapstream. Multiple chipboards can be inserted in a single location by varying the length of the chipboard ejector control pulse.
