Abstract: A set of document envelopes (1) suitable for continuous use on an automatically or semiautomatically operating device is disclosed. The device for carrying out the method of use carries out a number of steps on the set of envelopes (1) arranged in a row on a continuous strip (8), i.e. the strip (8) is fed past a work station (10) comprising input guide means (11), output guide means (12) and a strip feeding means (13); each envelope is opened by a means (14) and a document is inserted by a means (15), and each envelope (1) is grasped by a means (16) and separated form the carrier (8). The envelope/strip assembly consists of a stack of at least three continuous strips in which only the two strips defining said envelopes are cut or pre-cut.
