Abstract: The apparatus for automatically joining reels of web material includes a joining assembly adapted to take the trailing edge of a first expiring reel of web material and to apply it on the leading edge of a second reel of web material. Said leading edge is held close to said second reel of web material by gripping means rotated, at the same angular speed, by the same second reel. Said leading edge bears, on the side facing outwardly, a label of adhesive material.

Abstract: Apparatus (10) for bending tubular products (100) wherein each tubular product (100) is provided with a flexible portion (111) configured to allow a bending of the tubular product (100). The tubular products (100) are disposed, at least temporarily, on positioning means (19), while bending means (18) each allow the bending of a respective tubular product (100) in correspondence with the flexible portion (111).

Abstract: Automatic packaging machine (3) for filling a bag (1) made of heat-sealable material, having an open upper end (2) with a dose of loose product; the packaging machine (3) has: a packaging conveyor (4); a pick-up head (7), which is supported by the packaging conveyor (4) to advance along a packaging path (P1); an input station (S1) where the empty bag (1) is grabbed by the pick-up head (7); an output station (S2) where the full, sealed bag (1) leaves the pick-up head (7); a filling device (18) that is mounted on the packaging conveyor (4) to move together with the pick-up head (7) along the entire packaging path (P1) and is adapted to supply the dose of product inside the bag (1) through the upper open end (2); and a sealing device (19) that is mounted on the packaging conveyor (4) to move together with the pick-up head (7) along the entire packaging path (P1) and is adapted to seal the full bag (1) through a heat-seal in correspondence with the open upper end (2).

Abstract: A product packaging machine comprises a conveyor (4) for feeding the products along an axis (D) in a feed direction (V); a grouping station (5) for the products (3) located downstream of the conveyor (4) along the feed direction (V) for grouping the products (3) into a group (2) of products (3); the group (2) has at least a first and a second layer (6, 7) of products (3); at the grouping station (5), the machine (1) comprises stacking means (11), by which at least the first and the second layer (6, 7) are stacked from the bottom up; more specifically, the stacking means (11) raise the first layer (6) from the bottom up and stack the second layer (7) from below, under the first layer (6).

Abstract: Packets of prismatic geometry referable to a longitudinal axis, presenting two larger side faces, two smaller flank faces and two end faces, are overwrapped by a method including a step in which each packet, enveloped initially by a tubular wrap projecting beyond the two end faces, is inserted into a holder of a transfer wheel in such a way that two appendages of the tubular wrap projecting at either end from a first flank face of the packet are flattened over the end faces; the appendages are pinned immediately along two lines coinciding substantially with the corner edges of the end face as the packet enters the relative holder, and held stably in position during a subsequent step of transferring the single packets from a feed station to an outfeed conveyor.

Abstract: A method of overwrapping packets in the form of a rectangular prism, whereby a packet, as it is fed continuously along a wrapping path, is first centered with respect to a relative conveying seat, and is then paired with a relative sheet of wrapping material, which is folded about the packet to form a tubular wrapping projecting axially from the packet in the form of two tubular appendixes, which are folded to form a closed overwrapping; each tubular appendix being at least partly folded onto the relative packet before the relative tubular wrapping is completed.

Abstract: A method of wrapping elongated articles in groups provides for feeding a first and a second pocket continuously along two respective paths having a common portion, along which the first pocket penetrates the second pocket to transfer a group from the first to the second pocket together with a sheet of wrapping material, which is folded into a U inside the second pocket and has two parallel, opposite flaps gripped between first and second lateral walls; and for compressing the group between a first and a second bottom wall and, at the same time, extracting the first lateral walls from the second pocket.

Abstract: A method of transferring wrappings, wherein each wrapping is defined by a sheet of wrapping material and has at least one flat wall, provides for feeding a wrapping along a curved path by means of a pocket of a conveyor; for guiding the wrapping along the curved path by means of a guide contacting the wrapping; and for moving a plate of the guide with respect to the pocket, so that a flat face of the plate is maintained contacting the entire flat wall of the wrapping along a portion of the curved path.
