Improved Shingler Design

This article describes an improved device for serially moving sheets of paper from a paper stack.

A rotating wheel 10, carrying multiple rollers 11 along the periphery thereof, is placed in contact with a paper stack (not shown). The result is to rotate the nondriven rollers and create waves in the paper stack which "shingle" the stack such that the paper sheet in direct contact with the rollers moves away from the remaining sheets.

In the design shown, a molded hub 12 made from a rigid plastic, such as polycarbonate, is provided complete with two sidewalls 13 and 14. Each side wall has large holes 16 at the axle position of rollers 11. A suitable soft material 17, such as urethane or neoprene, is molded into the large hub holes, leaving only small holes for the roller axles 15.

It will be appreciated that in this design the axles 15 are held centrally located in place by compression of the soft material between the axle and the rigid plastic sidewall. The soft material gives good damping characteristics to the rollers, thus holding noise to a minimum. In addition, side skew of the rollers is resisted by the rigid plastic hub.
