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.

Packaging unit for producing sealed packages containing a pourable food product from a tube of packaging material

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; the jaws are also cyclically movable in an intermediate position, which is arranged between rest position and seal position; folding flaps are movable relative to the jaws into a partly closed position, which is arranged between open position and fully closed position, when the jaws are set in intermediate position.

Packaging unit and method for producing sealed packages

A method of producing a sealed package of a pourable food product involving feeding a tube of packaging material along an axis; moving a pair of first jaws and a pair of second jaws cyclically and alternately along sealing paths parallel to the axis, and along repositioning paths; moving the jaws, as they travel along the sealing paths, into a closed position in which the sealing members grip the tube and respectively form, at different times, a first and a second seal sealing the tube and defining respective opposite ends of the package; and moving the jaws, as they travel along the respective repositioning paths, into an open position, in which they are detached from the tube; acquiring a desired value of a quantity related to the package weight; and forming the second seal at a distance, which is a function of the value, from the first seal.
