ABSTRACT:
A stacker assembly for a prefolded continous web of paper is provided with an air jet means for directing an air stream onto the upper sheet of the paper stack being piled in the stacker to press down the folded edges in the stack. The direction and intensity of the air stream are controlled by means of a directional control device and an intensity control device. These control devices have variable settings in order to properly accommodate the particular form lengths of the paper being folded and the particular rigidity characteristics and weight of the paper. The two control devices may be connected via a mechanical coupling device so as to permit automatic adjustment in accordance with lateral displacement of form length guide walls positioned on opposed sides of the paper stack, these guide walls being displaced to accommodate prefolded web paper having different form lengths.
