Abstract: Leaflets are stacked horizontally in a stacker tray after folding, with the leaflets themselves aligned in a vertical orientation. A tray transport platform supports a plurality of tray sleeves and a plurality of corresponding trays located adjacent to the stacker tray. The trays can slide into the tray sleeves as each tray is filled with leaflets. A robot gripper is adapted to be selectively placed inside the stacking tray. The gripper captures a batch of the leaflets as they are stacked, and places them in a selected tray. A sleeve holder is selectively placed in and removed from the selected tray to control entry of the leaflets into a corresponding tray sleeve, and a stuffer pushes each batch of leaflets inside of the sleeve. A controller operates the components of the apparatus so that the leaflets are transferred from the stacker machine to trays without human labor.

Abstract: A side jogging mechanism for aligning a sheet to be folded into an outsert by an outsert folding apparatus comprises a frame including first and second oppositely disposed side frame members between which the outsert folding apparatus is received, an adjustable solenoid assembly mounted on the first side frame member, and a side stop assembly mounted on the second side frame member. The solenoid assembly includes a solenoid, a plunger extending from and actuated by the solenoid, and a pusher mounted at an end of the plunger located between the first and second side frame members. The side stop assembly includes a side stop located between the first and second side frame members. The solenoid assembly further includes an adjusting mechanism, e.g., a threaded shaft and handwheel, for adjusting the position of the pusher between the first and second side frame members, which adjusting mechanism is located outside the frame. Desirably, the side stop assembly also including an adjusting mechanism, e.g.
