Abstract: An assembly for producing sealed packaging units (14) from a sheet packaging material, comprises: an advancement device (21) for advancing the sheet packaging material along an advancement direction (F), a longitudinal sealing device for sealing opposite borders of the sheet packaging material along a longitudinal sealing band arranged parallelly to the advancement direction (F), thereby forming a continuous tube (15), a transverse sealing device (29) for sealing the continuous tube (15) transversely to the advancement direction (F), so as to define a sealed packaging unit (14). The transverse sealing device (29) comprises a sealing element (30) and an abutment element (31) that are intended to mutually cooperate during sealing while being located on opposite sides of the continuous tube (15). The sealing element (30) is so configured as to act on a side (27) of the continuous tube (15) on which the longitudinal sealing band is provided.

Abstract: A packaging unit for producing sealed packages from a tube of packaging material advanced along a first axis includes: at least two jaws arranged on opposite sides of the first axis and movable between a closed position, in which they grip and seal the tube and an open position, in which they are detached from the tube; at least two forming members supported by the respective jaws in a movable manner between a first operating position, in which, in relation to the position of the jaws, they have the maximum distance from one another, and a second operating position, in which they mate with one another and an actuator to produce movement of the forming members; the actuator includes at least one mover connected to both forming members and selectively activated to perform opposite strokes, along which the mover itself produces the movement of each forming members.

Abstract: There is described a packaging unit (1) for producing sealed packages containing a pourable food product from a tube (2) of packaging material advanced along a first axis (A); the packaging unit (1) comprises: at least two jaws (10, 11) arranged on opposite sides of the first axis (A) and movable between a closed position, in which they grip and seal said tube (2) of packaging material at one of a plurality of equally spaced cross sections, and an open position, in which they are detached from the tube (2); at least two forming members (15) supported by the respective jaws (10, 11) in a movable manner between a first operating position, in which, in relation to the position of the jaws (10, 11), they have the maximum distance from one another, and a second operating position, in which, in relation to the closed position of the jaws (10, 11), they mate with one another and cooperate with the tube (2); and actuator means (20) to produce movement of the forming members (15) between the first operating position a

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.
