High speed inserter fed from roll material

摘要

A method and apparatus for selective high-speed insertion of sheets from a plurality of webs into envelopes provides a mechanism for folding and inserting sheets into preformed envelopes. Preformed envelopes are provided for folding and inserting from a source that may be a roll. A plurality of sheets are fed for folding and inserting into an envelopes. A leading sheet from each of the webs is selectively driven and cut at a collection point for folding and inserting. The selecting of sheets for feeding and cutting may be accomplished by means of a CPU that may include a bar code detection system disposed along each of the webs. A system for widening the openings of envelopes to facilitate insertion of contents may also be included. This system may comprise a strip along each of the envelopes is a stream that includes a folded section within each opening or may comprise tabs disposed along an opening side of each envelope.
