A working process of a machine for wrapping products in packages, carried out with a thermoplastic material film from a reel, comprising: a loading station for the products to be packaged; a hollow mandrel with a relative forming shoulder; a sealing device for forming a seal of the longitudinal edges of the film; a horizontally mobile pusher for pushing a bundle of products from the loading station through the mandrel; a sealing and transversal cutting assembly formed by two vertically mobile elements mounted on a horizontally mobile primary carriage a conveyor a secondary carriage carried by the primary carriage; comprising the following operating steps: reducing the transversal section of the mandrel to a diameter smaller than the diameter of the bundle of products positioning the sealing device in a position for sealing the overlapped longitudinal edges of the film while forming a new tubular film casing; arranging the elements of the assembly in a closure position on the head portion of the new tubular film casing and on the tail portion of the tubular film casing of a finished package; and conveying of said new tubular film casing, by the movement of the primary carriage away from the mandrel, and repeating the preceding steps, so that the product placed inside the tubular casing by the mandrel is wrapped in a tight adherent manner due to the elastic retraction of the film of tubular casing.

There is provided a system for packaging objects on a conveyor using a tubular plastic film. More specifically, the invention provides a system, wherein the tubular plastic film can be wrapped around the objects in a horizontal manner.

A method for monitoring a tubular bag machine having a drive control system and independently controlled electronic drive units controlled by a drive control system for driving functional elements of the packing machine in a cycle time-synchronous manner in predefined motion sequences, one drive unit being a transverse sealing unit with a drive motor and two transverse sealing jaws for transversely sealing a film tube, and the drive motor torque measured using a drive controller, and the drive motor position measured using a position sensor, the method including moving the film tube into the sealing zone between the transverse sealing jaws, closing the jaws according to a predefined target torque stored in the drive control system, measuring the actual position of the drive motor upon reaching the target torque, and comparing the measured position to a target position stored in the drive control system associated with the predefined target torque.

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.

Adjustable tables for use in a packaging forming system and related methods are provided. An adjustable table for use in a packaging forming system can include outer side panels and moveable inner side panels moveably connected to the outer side panels with the outer side panels held stationary relative to the moveable inner side panels. The adjustable table can also include a table top secured to the moveable inner side panels. The table top and the inner side panels are configured to move upwardly or downwardly relative to the outer side panels.

The present disclosure relates to a method for producing an oral pouched snuff product comprising a filling material (29, 10) and a saliva-permeable pouch (43) enclosing the filling material (29, 10), the product (29, 10) having a moisture content of at most 20% by weight, in particular at most 10% by weight, based on total weight of the product (29, 10), the saliva-permeable pouch (43) having one or more seals (45, 46), and said filling material (29, 10) comprising at least 20% by weight, based on dry weight of the filling material (29, 10), of at least one ingredient having a melting temperature below 180 C., the method comprising ultrasonically welding and cutting an advancing web (32) of packaging material (7) to which the filling material (29, 10) has been supplied. The present disclosure also provides an oral pouched snuff product which is obtainable by this method.

The invention relates to a valve bag, in particular a cross-bottom valve bag, comprising a first wall and a second wall, which are joined to each other by means of side edges or side folds and by means of bottoms and which delimit a bag interior, comprising a valve, which is arranged in one of the bottoms and via which the bag interior can be filled with a filling material, and comprising venting openings in the first and/or in the second wall for venting the bag interior. At least one channel is provided on the outside of at least one wall, which channel covers the venting openings and is formed at least by two parallel fastening strips and by a cover strip, the cover strip likewise comprising venting openings, and wherein the shortest path between the parallel fastening strips along the cover strip is longer than the shortest path along the at least one wall or the cover strip, and/or the parallel fastening strips consist of stretchable material.

The invention relates to a plastic bag, in particular an FFS bag, comprising a first wall and a second wall, which are joined to each other by means of side edges or side folds and by means of bottoms and which bound a bag interior, wherein at least one bottom comprises a weld seam, which extends between the side edges and touches the side edges, and venting openings in the first and/or in the second wall for venting the bag interior, characterized in that at least one channel is provided on the outside of at least one wall, which channel covers the venting openings and is formed by at least two parallel fastening strips and by a cover strip, wherein the cover strip likewise comprises venting openings and wherein the shortest path between the parallel fastening strips along the cover strip is longer than the shortest path along the at least one wall between the parallel fastening strips or the cover strip and/or the parallel fastening strips consist of stretchable material.
