Abstract
A conveyor or article transportation system for conveying or transporting, for example, pieces or units of mail, or similar flat articles, has a pair of guide fingers operatively extending downstream from a downstream end of the conveyor so as to project into a stacking chamber within which the pieces or units of mail, or flat articles, are to be stacked. The guide fingers effectively vertically support the downstream end portions of the pieces or units of mail, or articles, such that the downstream end portions of the mail or articles do not curl or curve downwardly, or sag, whereby the pieces of mail or articles are deposited within the stacking chamber in a substantially flat state so as to prevent rollover of the pieces of mail or articles which would otherwise become jammed within the stacking system and cause upstream jamming or interruptions within the conveying system. In addition, the prevention of the curling or rollover of the pieces of mail or articles, in turn, prevents the pieces or articles from being stacked partially inside each other and therefore out of their previously sorted serial sequence.
