Title: Continuously sorting out individual sheets from stacking magazine - involves cogged rotatable restraints acting on upper stack part and supports for lower stack part coupled to brake acting on restraints
Inventor: RATHERT HORST
IPC: B65H1/06
Filed: 1992-06-03
Abstract: The rotary restraints (7,) engage from opposite sides into the stacking magazine to hold back and move on the sheets of the upper stack part. The brakes acting on the restraints are controlled by the weight of the lower stack part and are preferably friction brakes with rotary mounted brake shoes (12). When the upper stack part is supported on the restraining gearwheels (7) the side areas of the lower stack part are relaxed. If the lower part is now reduced as the printed sheet is removed, the brake action is reduced  by relaxing the pressure at the support angles which hold the lower stack part. The sheets of the upper stack can now be moved continuously over the restraining gearwheels. USE/ADVANTAGE - High speed separation even of flimsy sheets from stacking magazine.
