A method for producing a tube skirt for a flexible tube, said tube skirt being manufactured from a flat strip 1 comprising a decorative film 15 superimposed on a primary film 16, said primary film 16 comprising a sealable inner layer 14 at the lower surface 20 of the strip 1 as well as two stabilizing layers 11, 13, said decorative film 15 comprising a sealable outer layer 7 at the upper surface 19 of the strip 1, and a decorative layer 8, 9. This method comprises the following steps: winding the flat strip 1 into the form of a sleeve to shape the tube skirt; superimposing a first side border 2 of the strip 1 on a second side border 2 of the strip 1 to form an overlapping area 3, the sealable inner layer 14 of the primary film 16 of the first side border 2 overlapping the sealable outer layer 7 of the decorative film 15 of the second side border 2; applying a heating temperature T2 to the inside of the tube skirt at the inner face 22 of the overlapping area 3 to produce the side weld of the tube skirt; simultaneously with the application of the heating temperature T2, applying compression between the outer 21 and inner 22 faces of the overlapping area 3 so as to finalize the side weld of the tube skirt.

Various device embodiments perform a sealing operation on a moving web, and comprise, among other things a plate assembly with an air cylinder assembly. The air cylinder assembly comprises a mount, a back plate, at least one air cylinder positioned between the mount and the back plate. The first plate assembly further includes a linear servo motor for linearly moving the air cylinder assembly with respect to the first base, and a first tooling plate with a sealing surface area. The first tooling plate coupled to the back plate.

A system includes a film processing module, a processor, and memory. The processor and memory are in communication with the film processing module. The processor is configured to dynamically coordinate movement of the film processing module relative to a moving web of film and to perform a function on the web of film with the film processing module.

A film fin sealing device is disclosed herein which may have a groove defining a base. The base of the groove of the fin sealing device may be oriented at a skewed angle with respect to a longitudinal direction of the conveyor of a heat sealing machine. Edges of a thermoplastic sheet or two stacked layers of thermoplastic sheets are introduced into the groove of the film fin sealing device and placed in contact therewith to both heat and fuse the distal edge portions of the thermoplastic sheet(s) to join the edge portions thereof to form a fin seal.

A low mass staking module includes a punch having a cavity on a first side, a contact surface on the second side opposite the first side, and a circular flange extending about an outer edge thereof, the punch formed of a thermally-conductive material, an annular housing engaged with the punch about the circular flange at a first end, and a heating element located inside the annular housing. The heating element has an output side in contact with the contact surface of the punch, the contact surface having a shape conforming to a shape of the output side of the heating element. The punch is desirably a low thermal mass punch, while the heating element may be a high power (watt) density, solid state, ceramic, resistant heating element (e.g., aluminum nitride or boron nitride heaters).

A method and apparatus for manufacturing a tampon packaging where the packaging is manufactured separately from the tampon. A first transversal end is overlapped with a second transversal end of a strip of heat-sealable film. The first transversal end is heat sealed to the second transversal end of the heat-sealable film, thereby forming a tube of film.
