ABSTRACT:
An improved accumulator and method of accumulation into stacks of a number of seriatim-fed sheets selectively in the manner of "over" or "under" accumulation and for conveying accumulated stacks to further equipment. The accumulator comprises driven endless elastic belts to drive sheets therebetween and a driven roller pair for nipping and feeding the sheets to a stacking location to be accumulated therein. The nip of the roller pair is offset in relation to the plane in which sheets are driven thereto by the belts. The roller pair drives a sheet in positively nipped manner to the stacking location selectively over or under a previously arrived sheet. Further included in the roller-accumulator is a stop gate device for stopping sheets fed to the stacking location and for selectively releasing accumulated stacks to be transported by and between the endless elastic belts to further equipment.
