Abstract
A device and process for processing flat articles such as pieces of paper by utilizing a stream of under-shingled flat articles and generating a gap at predetermined intervals. The under-shingling process incorporates an accelerating and decelerating portion wherein each flat article is accelerated and then decelerated while a tail portion of the article is lifted such that the next flat article can slide underneath to establish an under-shingled stream.
Claims10
A device for processing flat articles, the device comprising:
- an under-shingling device;
- and
- a gap generation device configured for generating a gap at varying intervals of the under-shingled steam of flat articles, the gap generation device comprising:
- a first set of pinch belts configured to move the a first portion of the under-shingled stream of flat articles at a first speed;
- and
- a second set of pinch belts configured to move a second portion of the under-shingled stream of flat articles at a second speed during predetermined intervals, the second speed being greater than the first speed, wherein the first set of pinch belts and the second set of pinch belts are serially adjacent to each other along the undershingled stream of flat articles.

A method of processing a substantially flat article comprising:
- creating an under-shingled stream of flat articles;
- creating gaps at varied determined intervals of the under-shingled stream of flat articles, the gaps comprising a first gap and a second gap;
- placing a first obstacle in the first gap and in front of the under-shingled stream of flat articles;
- accumulating the under-shingled stream of flat articles into a first bottom fed, vertically created stack of flat articles;
- removing the first obstacle at the second gap;
- placing a second obstacle in the second gap and in front of the under-shingled stream of flat articles;
- and
- accumulating the under-shingled stream of flat articles into a second bottom fed, vertically created stack of flat articles.
