  • Patent number: 9334071
    Abstract: An apparatus for packaging stacks of folded tissue products or the like with blanks of plastic film, having at least one pocket, an insertion device for inserting, along an insertion direction, a single stack in the at least one pocket with the interposition and consequent folding of a corresponding blank, the at least one pocket being operatively associated with a stop member of the stack completely inserted within the pocket. The apparatus also has a control system adapted to operate the stop member in a coordinated manner with respect to the operation of the insertion device, to provide an abutment to the stack during the whole insertion step in the pocket, the stop member having suction devices to keep the film in position and to disengage the same film at least in an extraction step of the stack from the pocket.

  • Patent number: 8951179
    Abstract: A feeding unit from reels of sheet-like material , in particular but not exclusively printed plastic film with print-position marks for automatic packaging machines, comprising two unrolling shafts of respective reels of material for feeding in turn said material towards a unit that cuts and welds the tail of material of a running out reel and the head of a fresh, loaded reel. Such a unit comprising suction, cutting and welding devices (7, 8) movable so as to approach and move away from each other to press the material (F1, F2) over a welding plane. Each device is formed by a group of mutually stacked suction and cutting modules, at least two of such modules having respective guides for slidable in a transversal direction with the respect to the feeding direction of the material, whereby it is possible to select and adjust the number of modules according to a desired welding height.

  • Publication number: 20120100978
    Abstract: A feeding unit from reels (B1, B2) of sheet-like material (F1, F2), in particular but not exclusively printed plastic film with print-position marks for automatic packaging machines, comprising two unrolling shafts (1, 2) of respective reels (B1, B2) of material (F1, F2), for feeding in turn said material towards means (7, 8) for cutting and welding the tail of material of a running out reel (B1) and the head of a fresh, loaded reel (B2). Such means comprise suction, cutting and welding devices (7, 8) movable so as to approach and move away from each other to press the material (F1, F2) over a welding plane (Z). Each device is formed by a group of mutually stacked suction and cutting modules, at least two of such modules having respective guides for cutting means slidable in a transversal direction with the respect to the feeding direction of the material, whereby it is possible to select and adjust the number of modules according to a desired welding height.

  • Patent number: 5459979
    Abstract: Apparatus for continuously feeding a drum machine with compressible articles for the wrapping thereof, comprising structure for progressively and continuously compressing the packs 1 to be wrapped which are fed by a belt conveyer 10, and at the same time transferring them towards the revolver 2 of a wrapping machine by means of a pair of superimposed belt conveyers 4 converging towards the revolver 2 of a wrapping machine by means of a pair of superimposed belt conveyers 4 converging towards the revolver 2 and each being operated by a relevant driving roller 40 parallel to the axis 21 of rotation of the revolver 2. The packs 1 being interposed individually and in succession between the belt conveyers 4. A device is provided for cyclically varying the feeding speed of the belt conveyers 4, and another device is provided for driving each of the belt conveyers 4 into an alternative rotation of predetermined angular amplitude about an axis 41 parallel to the axis 21 of rotation of the revolver 2.
