Sheet jogging assembly

Abstract

Disclosed is a sheet jogging assembly for use in a sheet registering apparatus in which sheets are collected at a receiving station and arranged in registration with each other for performing an operation on the collected stack of sheets. The invention is utilized particularly in machines for stitching, stapling or punching stacks of sheets which have been collated into booklets, the sheets having been delivered to the stitching, stapling or punching machine by a suitable feeding apparatus. The registering apparatus operates on the rear edge of the sheets after they are deposited on a receiving tray and incorporates mechanism by which a jogging device can be adjustably set to an infinite number of operating positions between predetermined limits which allows the machine to handle sheets ranging from approximately seven inches to approximately fourteen inches in length. The driving assembly for the jogging device is taken directly off the drive for the stitching, stapling or punching machine and the jogging device is adjustable along the driving assembly so that it can be locked in the aforementioned infinite number of operating positions along the driving assembly by the operator. The jogging device includes a jogging assembly having a sheet supporting member which moves back and forth as sheets are jogged into registration. A jogging element having a sheet contacting jogging surface is adjustably mounted on the jogging assembly in order to still further extend the range of positions of operation of the jogging element. An auxiliary adjustment of the paper jogging element allows for still further extension of the range of positions for the jogging element.
