A take-off mechanism for delivering a series of sheets from a conveyor onto a delivery pile. Positive transfer of the sheets from the grippers on the conveyor to the jaws of the take-off mechanism is effected by moving the jaws along a take-off path which coincides with the conveyor delivery path and at the same speed as the sheet and by engaging the jaws prior to the time the grippers are released. Stationary cams are used to close and open the jaws adjustable for both the timing and amount of opening. The transport mechanism for the take-off jaws includes cams synchronized with the conveyor for imparting separate horizontal and vertical components of movement to the jaws so that the jaws move in a predetermined closed loop path having transfer, deceleration and return portions. |
