Abstract

Disclosed herein is a method which allows insertion of a sheet of aper into the to provide an insertion pocket for the next sheet. This device provides a simple, low cost means for building a low volume stack of paper from the bottom up. Furthermore, the device has a minimal impact upon machine configuration.

As disclosed, the present system applies to a small stack of approximately 25 to 30 sheets of 20# paper. The latitude of the system could be expanded to handle a wider range of paper weights by floating the stack, as is now accomplished in current document handlers. Restacking concerns may be alleviated by controlling the air flow in the pocket region of the device.

The disclosed invention, as illustrated in the accompanying figure, is depicted in a horizontal orientation. However, other orientations including a vertical implementation could make the scheme fit machine architectures to minimize the impacts of gravity and sheet to sheet friction parameters.

It is important to note that at the lower operating speeds...
