Abstract
An apparatus is provided for transporting layers of sheets in which the layers of sheets are carried off discontinuously transversely to the direction in which they are supplied and follow the layers of sheets previously carried off. The apparatus comprises a belt conveyor running at a substantially constant velocity, and a belt run with upper and lower belts which is connected in front of the continuously running belt conveyor and overlaps it at least in part. The belt run may be driven intermittently at a velocity varying between standstill and a higher velocity than that of the belt conveyor. The distance between the upper and lower belts may be varied cyclically.
Claims16
An apparatus for transporting articles, comprising:
- a belt conveyor adapted to run at a substantially constant velocity;
- a belt run, formed by upper and lower belts, which is disposed upstream of the belt conveyor, although overlapping the belt conveyor at least in part;
- means for intermittently driving the belt run at velocities different than that of the belt conveyor;
- and,
- means for cyclically increasing and decreasing the distance between the upper and lower belts for loading and engaging the articles, and for raising only the downstream end of the upper belt to release the articles in the overlapped region.
