  • Publication number: 20140228193
    Abstract: A folding unit for producing packages of pourable food products from sealed packs having each a main portion and opposite end portions arranged on opposite sides of the main portion; each pack comprises a fin and a pair of flaps projecting laterally from main portion; a first movable conveying member fed with a plurality of packs and which feeds the pack along a forming path; and folder which interacts with each pack along forming path to fold relative first end fin onto the portion; the folder comprising: a first member movable along forming path together with the conveying member and defining a slot receiving, in use, end fin; and a second member movable relative to first member between a first position in which it engages at least partially slot, so as to fold end fin onto a relative end portion, and a second position in which it leaves free slot.

  • Publication number: 20140194267
    Abstract: A folding unit for producing folded packages of pourable food products from sealed packs, comprising: movable conveyor which are fed with a plurality of packs at an input station, which feed packs along a forming path and output folded packages at an output station; and folder cooperating with each pack to perform at least one folding operation on pack comprising: at least one pair of shells which are integrally movable along the forming path and are movable relative to each other along a direction transversal to the forming path; shells of each pair may be set along the direction in: a fully closed position in which they exert a pressure onto a relative pack, so as to at least complete a folding operation onto relative pack; and an open position in which they are detached from the corresponding folded package.

  • Patent number: 8584927
    Abstract: Packaging material configured to be folded and sealed to produce a gable-top package for pourable food products comprises a web of material provided with a crease pattern along which the web of material is foldable. The crease pattern includes first and second transverse fold lines extending transversely across the material web, and a plurality of longitudinal fold lines extending longitudinally away from the first transverse fold line toward the opposite longitudinal end of the web of material, with adjacent pairs of the longitudinal fold lines defining respective walls of the gable-top package when the packaging material is folded and sealed. The crease pattern also includes a pair of oblique fold lines extending obliquely from the first transverse fold line to the second transverse fold line such that an area enclosing triangular panels is bounded by the oblique lines and portions of the first and second transverse fold lines.

  • Patent number: 8231514
    Abstract: A folding assembly for producing a gable portion of a sealed package of pourable product, wherein the gable portion has first and second walls sloping with respect to each other and joined at a seal, and a flap connecting lateral edges of the first and second walls. The folding assembly is supplied with packs, each having an axis and, at one end and on opposite sides of the axis, two end portions which are folded to form the gable portion, with the end portions having, respectively, a first and a second portion to be folded, which are joined by a lateral face of the pack. The folding assembly includes a folding mechanism which interacts, on opposite sides of the axis, with the first and second portion of the pack to fold the second portion onto the lateral face, and the first portion onto the second portion to form the flap.

  • Patent number: 7955242
    Abstract: A folding unit for producing sealed packages of pourable food products from respective packs, each having a main portion folded into a desired shape, and opposite end portions to be folded to form respective folded ends of a relative finished package. The unit has a first folding station, in turn having a first retaining mechanism for securing each pack by a relative first end portion, and a first folding mechanism for folding a relative second end portion of the pack. The unit also has a second folding station located downstream from the first folding station in the traveling direction of the packs, a second retaining mechanism for securing each pack by the relative folded second end portion, and a second folding mechanism for folding the relative first end portion.
