ABSTRACT:
An envelope stacking system is described which has a wide-angled inlet window for easily inserting envelopes upon an envelope stacking deck. The envelopes are thrust towards a guide wall by means of constantly rotating friction rollers. Once an incoming envelope is received it is displaced from the friction rollers to prevent damage to the envelope. The displacement of the envelope also serves the purpose of freeing the inlet for the next incoming envelope. In this way, the inlet window is cleared to accommodate each incoming envelope. The stack is biased toward the inlet and friction rollers, but a lip disposed upon the deck prevents the stack from blocking the inlet window or from engaging with the friction rollers.
