Overlap conveyor apparatus

摘要

This conveyor apparatus is used primarily with continuous business form processing machines to provide a means of producing a stream of overlapped blanks disposed on a continuous web. The apparatus includes upper and lower conveyors. The upper conveyor is formed from a pair of endless flexible elements having transversely aligned wedge-shaped pins disposed along the length thereof with inclined trailing flanks. Document blanks are fed onto the upper conveyor such that the leading edge rides up and beyond an aligned pair of associated pins an the trailing edge is engaged by a pair of following pins. Each of the blanks is pushed by a pair of transversely aligned pins in overlapped relation to the preceding blank. The document blanks are removed from the upper conveyor and deposited in reverse overlap relation onto gum lines provided on the continuous web carried by the lower conveyor.
