Abstract: The invention relates to a forming device (42) for feeding along a forming path (B) a pack (3) which has at least one portion (6) to be folded into a finished package (2). The forming device (42) comprises a first surface (46a) and a second surface (46b) opposite to each other and adapted, in use, to cooperate respectively with a front wall (15) and a rear wall (10) opposite to each other of the pack (3) to be folded. The first surface (46a) comprises an at least partially concave forming section (8) adapted, in use, to cooperate with a top portion of the front wall (15) of the pack (3), such that an inward deformation of the top portion of the front wall (15) is prevented during forming of the pack (3). The invention also relates to a folding unit (1) for forming sealed packages (2) of pourable food products, to a method for forming a pack (3) which has at least one portion (6) to be folded into a finished package, and to a package (2).

Abstract: There is described a folding unit for forming sealed packages of pourable food products, comprising: at least one conveying device for feeding along a forming path a relative pack which have at least one portion to be folded to form a finished package; at least one folding device interacting, in use, with pack along said forming path and adapted to fold said at least one portion; conveying device comprises a first and a second surface opposite to another and adapted, in use, to cooperate respectively with a front and a rear wall opposite to each other of relative pack to be folded; first surface is at least partially concave.

Abstract: There is described a forming member for controlling the volume of packs of pourable food products formed from a tube of packaging material and sealed at a number of sections of tube crosswise to an axis of tube, comprising: a wall comprising, in turn, a first surface which is adapted to interact with a first portion of tube; and a pair of sidewalls protruding from wall on the same side of wall, and comprising respective second surfaces which are adapted to interact with relative second portions of tube; first surface is at least partially concave.

Abstract: A forming jaw for producing a succession of sealed packages from a tube of sheet packaging material filled with a pourable food product and fed in a direction parallel to its longitudinal axis is disclosed. The jaw includes sealing structure that seals a cross section of the tube; and forming structure that imparts a predetermined shape to the tube between two successive sealed cross sections. The forming structure has first and second surfaces for interacting with the tube and which extend respectively in a direction crosswise to, and in a direction parallel to, the axis of the tube. The first surface has a convex portion which exerts pressure on, to control filling of, the packages being formed.
