Abstract
A device for collating sheets of paper into a stack includes an elongated chute and at least one feeder. The chute has a transverse shape approximating the size of the sheets of paper to be fed into the chute. Each feeder feeds a sheet of paper into the chute so that the plane of the paper extends generally transverse to a vertical axis of the chute. The sheets of paper thus fed into the chute may then float downwardly on a cushion of air coming to rest in a bottom area of the chute.
Claims13
A device for collating sheets of paper, the device including:
- (a) a substantially vertical and elongated chute having a first side wall and an opposite side wall, the first side wall and opposite side wall extending substantially parallel to each other and being spaced apart a distance greater than a side dimension of the paper to be collated;
- (b) a collection station positioned at a bottom of the chute;
- (c) a first feeder positioned on the first side wall of the chute for feeding a first sheet of paper into the chute so that the first sheet of paper extends generally transverse to a vertical axis of the chute, the first feeder positioned on the first side wall outside of the area defined by the chute between the first side wall and opposite side wall;
- and
- (d) at least one additional feeder positioned on the first side wall of the chute, each respective additional feeder being positioned at a different spaced apart position along the vertical axis of the chute with respect to the first feeder and outside of the area defined by the chute for feeding a respective additional sheet of paper into the chute so that the respective additional sheet of paper extends generally transverse to the vertical axis of the chute.
