An induction heat sealing device for providing a transversal sealing of a tube of packaging material, said induction heat sealing device including a main body including a first and a second sealing surface arranged to face the packaging material during a sealing state, a recess provided in the main body for receiving a knife during a cutting state, wherein the first and second sealing surface are placed on opposite sides of the recess, and an electric conductor arrangement, provided in the main body, for inducing eddy currents in the packaging material during the sealing state, wherein at least part of the first and second sealing surface are inclined and provided with a first and a second top section, respectively, such that particles in a product held inside the tube are pushed away from a sealing band of the tube as the sealing band is pressed toward the first and second top section.

The present disclosure relates to an oral pouched snuff product and a method for its production. The oral pouched snuff product comprises a filling material and a saliva-permeable pouch enclosing the filling material, the saliva-permeable pouch comprising at least one elongated seal and the saliva-permeable pouch comprising a mesh material being elastic in at least one direction and comprising fibres of thermoplastic polyamide, wherein the at least one elongated seal has a seal strength of at least 0.10 N/mm as measured in dry state as well as in wet state. The at least one elongated seal may be an ultrasonically provided weld.

A foam structure includes: a first core material and a second core material that are obtained by splitting a foam body at a linear groove part, the groove part being formed in the foam body for fitting with a reinforcing material, and the reinforcing material into which the first core material and the second core material are respectively fitted from one side and the other side of the reinforcing material.

The present disclosure discloses an apparatus and method for sealing a pouch case that optimizes a sealing shape or structure of a sealing portion at an inner side of the pouch case to ensure insulation of a secondary battery. The apparatus for sealing a pouch case of a pouch-type secondary battery according to the present disclosure includes an upper compression jig to apply pressure to a sealing portion of the pouch case in a downward direction, and a lower compression jig to apply pressure to the sealing portion of the pouch case in an upward direction, and at least one of the upper compression jig and the lower compression jig applies the pressure to the pouch case at different depths at an inner side end and an outer side end.

When overlapping and joining together end portions of a rubber member, it becomes possible to join them at a joining area smaller than a conventional one by increasing the joining area. There is provided a joining device for overlapping end portions, of a rubber member (tire constituent member) with one upper end portion placing on the other lower end portion and joining the end portions of the rubber member, in which a pressing roll (disk-shaped roll) rotating about an inclined shaft is rolled while being pressed against the overlapped upper end portion of the rubber member, and the upper end portion is extended by a shearing force generated at this time to increase a joining area between the both end portions.

An ultrasonic sealing tool including an anvil with a sealing surface, a horn with a sealing surface facing the sealing surface of the anvil, the sealing surface of the anvil including a plurality of beads including a first bead having a first height and at least one second bead having a second height, the second height being less than the first height, the ultrasonic sealing tool delivering ultrasonic vibrations via at least one of the anvil and the horn to create a closure seal in a work piece positioned between the anvil and the horn, the closure seal including a first seal created by the first bead and at least one second seal created by the at least one second bead, the first seal having a weld depth greater than a weld depth of the at least one second seal.

The present invention is directed to a method forming a bottom-gusseted package, wherein each package includes an inwardly-extending, pleat-like gusset at the bottom of the package. To permit heat-sealing formation of each package, the sleeve from which each gusset is formed comprises a lamination of two differing polymeric materials, so that only an exterior surface of each sleeve exhibits the desired heat-sealing characteristics. To facilitate package formation, the sleeves from which the bottom gussets are formed are maintained in a temporarily closed or sealed configuration during package formation by providing a preferably frangible bond or seal at the edge of each sleeve. This result is preferably achieved by folding the laminate material, and temporarily sealing or joining an outer layer of the laminate material from which gusset is formed, while an inner layer is maintained in an unsealed condition.
