An inductor for induction welding of a packaging material having at least one layer of metal foil is disclosed. The inductor comprises a welding surface configured to be arranged opposite the packaging material for heating thereof, and at least one spacing element arranged to protrude from the welding surface in a first direction towards the packaging material, when the packaging material is arranged opposite the welding surface, whereupon the least one spacing element separates the packaging material from the welding surface by an off-set distance. A sealing machine for sealing packaging material and a method of welding a packaging material is also disclosed.

A drive assembly (17) to move tubular bag material past a former and deliver a tubular bag material to a packaging machine. The drive assembly (17) includes a pair of drive belts (6) that are parallel and driven in unison by means of a drive pulley (29) and either pulleys (30, 31).

A method (700) for assessing quality of a longitudinal sealing (402, 502) in a roll fed packaging machine. The roll fed packaging machine comprises a packaging material receiver arranged to receive a web (104) of packaging material (202), wherein the packaging material (202) comprises an outer protective layer (204), an inner protective layer (206) and an intermediate strengthening layer (208), and wherein the web (104) has a first (302) and second (304) longitudinal side section, a strip receiver arranged to receive a protective strip (106), wherein the protective strip (106) has a first (306) and a second (308) longitudinal side section, a strip applicator (122) arranged to form a longitudinal strip sealing (502) by applying the protective strip (106) on the web (104) by heating the web (104) and the protective strip (106) and pressing the web (104) and protective strip (106) together and a strip application camera (108) arranged to capture strip application image data from a strip application area (310). The method comprises receiving (710) strip applicationimage data of the strip application area (310), extracting (712) features from the strip application image data, wherein the features are related to effects of the heating provided by the strip applicator (122), determining (714) a strip application status by evaluating the features, wherein the strip appication status relates to the quality of the longitudinal strip sealing (502), and transmitting (716) the strip application status, thereby providing a quality assessment of the longitudinal strip sealing (502).

The present invention relates to a method for portion-packing of an oral pouched snuff product (1′, 1″). The method comprises a) supplying and advancing a tubular web (19, 19′, 19″) of packaging material enveloping a continuous feed (23, 23′, 23a″, 23b″) of filling material in a direction of travel (L), b) forming transverse seals (39) in the tubular web across the continuous feed of filling material by means of ultrasonic welding, the transverse seals extending in a transverse direction (T) being perpendicular to the direction of travel. The present invention further relates to an arrangement (17, 17′, 17″) for portion-packing of an oral pouched snuff product.

A former assembly (10) including a base (11) to which there is attached a frame (12) that supports a sleeve (13). The sleeve (13) encloses a generally upwardly extending passage (14) to which product is delivered in batches from a weighing machine. Fixed to the internal surface (20) of the former shoulder (15) are heaters (24) that heat the external surface (16) over which the film bag material passes to be heated thereby.

The machine also includes a second driving assembly located upstream the longitudinal sealing tool and configured for moving the re-closable strip at a third forward movement speed, the first, second and third forward movement speeds being equal.

Vertical packaging machine for generating packages from a film that according to one embodiment includes a film feeder and a forming tube with a longitudinal axis. The forming tube configured to impart a tubular shape to the film. The machine is configured for incorporating a longitudinal tool for longitudinally sealing the longitudinal ends of the tubular-shaped film together and generating a film tube. The machine also includes a module for moving the film tube, and a transverse tool for transversely sealing and cutting the film tube. The module is configured for rotating with respect to the longitudinal axis of the forming tube, being arranged in different operating positions, such that it allows arranging the longitudinal tool required in different positions for generating packages having different topologies and/or different sizes without the need of moving the transverse tool.
