Abstract: According to a method for packaging articles with a film of plastic material, a band of plastic film (6) is supplied to conveying means (5), while a strip of glue (18) is applied along a longitudinal edge of the band of plastic film (6) and zones of glue (19), regularly spaced apart, are applied crosswise to the band of plastic film (6). A series of articles (2) to be packaged are supplied to the conveying means (5), above the band of plastic film (6) in positions between the transversal zones of glue (19) and then the longitudinal edges of the band of plastic film (6) are folded to form a tube around the articles (2), so as to overlap the edges of the band of plastic film (6). The edges of the band of plastic film (6) are pressed to stabilize joining and the transversal zones of glue (19) are also pressed while cutting at the same time the band of plastic film (6) crosswise in portions located between the transversal zones of glue (19), in order to obtain single packages of articles (2).

Abstract: A machine for inserting sheets into envelopes, the machine includes sheets feeder means for delivering the sheets on an underlying sliding surface; lugging means disposed along said sliding surface and operated by a related endless conveying line to engage trailing edges of said sheets to move said sheets toward a sheet inserting station disposed along the sliding surface downstream of said conveying line, an envelope feeder enclosing a stack of envelopes, said envelopes feeder being situated beside said sliding surface and capable, of removing continuously single envelopes from the bottom of said stack and feeding each single envelope to the inlet of an additional conveying line, placing said single envelope arranged in such a way that the back wall of the envelope, to which the closing flap of the envelope is hinged, faces downwards, so that the opening for inserting the sheets faces upwards and backwards, with respect to the inlet of said additional conveying line, said additional conveying line extending
