Paper bag or sheet ejection in mfg. machine - by raising rear edges of bags or sheets for overlapping and stacking

摘要

The individual sheets or bags are fed into the ejection device and onto a roller. The paper sheets leave the roller to pass between two belts which transport the paper sheets onto a second roller. A finger situated between the belts bends the trailing edge of each sheet upwards to facilitate stacking, and fingers allow the sheets to overlap while passing over the second roller which rotates at a slower speed than the first. The sheets are stacked onto an inclined conveyor belt fitted with a number of stops which support the stacks. The stacks are then taken off by a conveyor which has a roller mounted on a pivotal arm to remove the stacks from the inclined conveyor.
