摘要:
A machine for inserting sheets into envelopes, the machine includes sheets feeder means (D) for delivering the sheets on an underlying sliding surface (S); lugging means (T) disposed along said sliding surface and operated by a related endless conveying line (T1) to engage trailing edges of said sheets (F) to move said sheets toward a sheet inserting station (I) disposed along the sliding surface (S) downstream of said conveying line (T1), an envelope feeder (1) enclosing a stack (P) of envelopes, said envelope feeder being situated beside said sliding surface (S) and capable of removing continuously single envelopes (10) from the bottom of said stack (P) and feeding each single envelope to the inlet (A) of an additional conveying line (2), placing said single envelope (10) arranged in such a way that the back wall (11) of the envelope, to which the closing flap (13) of the envelope is hinged, faces downwards, so that the opening (12) for inserting the sheets (F) faces upwards and backwards, with respect to the inlet (A) of said additional conveying line (2), said additional conveying line (2) extending between said envelope feeder (1) and said sheet insertion station (I) an including gripping means (3) arranged stepwise and aimed at taking over each single envelope (10) still arranged in the same way, and at transferring each single envelope (10) to the sheet insertion station (I) in suitable advance relation with respect to the arrival of the respective sheets (F),, while keeping the envelopes oriented in the same way, with the related back wall (11) and closing flap (13) turned downwards, so that the opening (12), through which the sheets (F) are to be inserted, is turned upwards, crosswise to the sliding surface (S).
摘要:
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).
摘要:
The proposed method for conveying sheets to a accumulating apparatus includes the following working steps:
longitudinal cutting of a webstream (1), moved in a first feeding direction (A), to obtain at least two longitudinal sections; partial overlapping of the above longitudinal sections; transversal cutting of the longitudinal sections, to obtain a pair (20) of sheets (21, 22), partially overlapped; placing of the pairs (20) of sheets (21, 22) on a conveyor (3), moved in a second feeding direction (B), orthogonal to the first feeding direction (A), to define a plurality of pairs (20) of sheets (21, 22), each of which has at least one accessible portion (22A) of prefixed and constant extension (G).
