ABSTRACT:
This device is for use for fan-folding and stacking a continuous web of business forms and operates as the last stage of such processing machine. The device includes a pair of rotatable paddle wheels disposed on each side of the processing machine frame and having an axis of rotation perpendicular to the longitudinal axis of the frame. Each paddle wheel includes a hub rotatable in a plane parallel to the axis of the frame and a plurality of radially extending lengthwise adjustable arms pivotally attached to the hub for transverse movement out of and into the plane of rotation of the hub for selective engagement with the continuous web. The transverse movement of the arms is controlled by a circular cam fixedly attached to the frame and engageable by cam followers attached to said arms.
