    摘要： 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 and the second operating position; the actuator means (20) comprise at least one mover (21) connected to both forming members (15) in any position of the jaws (10, 11) and selectively activated to perform opposite strokes, along which the mover (21) itself produces the movement of each forming members (15) in opposite directions.

    摘要： A packaging unit for producing sealed packages from a tube of a sheet packaging material fed along a feed path having a first axis; unit comprises: jaws movable cyclically along path between a seal position in which they grip and seal tube to form sealing bands of packages, and a rest position in which they are detached from tube; and folding flaps fitted movably to jaws; folding flaps are movable between: an open position in which they are detached from tube, and a fully closed position in which they cooperate with tube for forming folded flaps in package; jaw means are also cyclically movable in an intermediate position, which is arranged between rest position and seal position; folding flaps are movable relative to jaws means into a partly closed position, which is arranged between open position and fully closed position, when jaw means are set in intermediate position.
