Abstract
The production of offset stacks of business forms is effected in a continuous (i.e. without interruption) manner until a vertical stacker into which the forms are fed is full. Between a detacher and the stacker, the forms are automatically and continuously directed either to the left or the right from a common center line to offset the forms into different groups with at least one form in each group. This offsetting action may be accomplished by a pair of angled conveyor belts with steel balls movable into and out of association with the conveyor belts by solenoids, and/or by two sets of diverter wheels which are also angled and which are moved up out of engagement with the forms or down into engagement with them. Edge guide rods are provided which are part of transport aligning mechanisms that are movable toward and away from each other to accommodate different form widths. Sensors are provided for sensing the first and/or last form in each group, and operate through a controller to switch the offsetting action.
