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.

Packaging material with crease pattern

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.
