A process for producing a tube, comprising forming a blow-molded article and removing a bottom portion of said blow-molded article. The blow-molded article includes (i) a head portion, and (ii) a tube portion integral with said head portion. The tube may be decorated, such as with a label.

The invention relates to a sealing tool (100) with a sealing surface (110) for sealing sheets (200) of metallized substrate, such as metallized paper or metallized plastic material, in cooperation with a sealing tool counterpart (190), which is arranged opposite to the sealing tool (too) with respect to the sheets (200) that are to be sealed. The sealing surface (no) comprises a plurality of sealing sections (111-115), which all face in the same sealing direction (SD) of the sealing tool (100), and has a sealing width extending transversely to the sealing direction (SD) of the sealing tool (100) from an outer sealing tool side (121) to an inner sealing tool side (122). The sealing sections (111-115) are arranged side by side in a stepwise manner so that, from the outer sealing tool side (121) to the inner sealing tool side (122), every sealing section (111-115) is offset from its neighbouring sealing section (111-115) in a direction opposite to the sealing direction (SD) of the sealing tool (100). The invention also relates to an apparatus (300) for sealing two sheets (200) of the metallized substrate with the sealing tool (100). Further, the invention relates to a packaging (400) for enclosing a substance and a method of producing such packaging (400).

A yarn or thread may include a plurality of substantially aligned filaments, with at least ninety-five percent of a material of the filaments being a thermoplastic polymer material. Various woven textiles and knitted textiles may be formed from the yarn or thread. The woven textiles or knitted textiles may be thermal bonded to other elements to form seams. A strand that is at least partially formed from a thermoplastic polymer material may extend through the seam, and the strand may be thermal bonded at the seam. The woven textiles or knitted textiles may be shaped or molded, incorporated into products, and recycled to form other products.

A method of reinforcing a seam on a body involves folding a seam allowance into a series of accordion folds to form a series of parallel reinforcement layers. The parallel reinforcement layers are of similar size and form a ridge. A ridge cap of flexible material is placed over the ridge. The ridge cap provides at least one further parallel reinforcement layer. The method involves securing the ridge cap and parallel reinforcement layers together with rows of stitching, with the stitching extending through all of the parallel reinforcement layers.

A fin sealer and method to seal a radially outwardly directed fin of a tubular web structure by directing the fin through a nip between a first and a second fin sealing rollers while communicating heat to the fin through at least one of the fin sealing rollers is provided. The fin sealer is configured to maintain a nominal face-to-face relation between an outer annulus of the first fin sealing roller and an outer annulus of the second fin sealing roller with a flexible connection between a hub element of the second fin sealing roller with the outer annulus of the second fin sealing roller.

A machine and method for welding sheets of plastic material. The machine includes a housing with a lower weld bar and an upper weld bar. A vertically-oriented gap is defined in a gripper assembly pivotally mounted to the housing beneath the work surface. A sheet of material is laid over the work surface covering the lower weld bar and gap. The upper weld bar is lowered to hold the sheet in place and a pusher plate is lowered relative to the upper weld bar to push some material into the gap, thereby creating a fold in the material. After withdrawing the upper weld bar and pusher plate, the gripper assembly is pivoted through ninety degrees and lays some of the folded material over the lower weld bar. The upper weld bar is lowered to weld a portion of the folded material and thereby create a pocket in the material.

Connections of sub-elements formed at least partly from fiber composite materials of a component for an aircraft with relatively low manufacturing complexity and the same or improved reliability and improved sealing, by providing different seam connections between the sub-elements. For this purpose, at least an edge region, formed from fiber composite material, of the first sub-element is formed to give a foldover that engages with an edge region of the other sub-element. Preferably, the forming is effected especially with use of thermoplastic materials while heating preferably the entire edge region.

A sealing tool includes an anvil and a horn, at least one of which includes a sealing surface having a gusset sealing section and a zipper sealing section, each configured differently than the other. The gusset sealing section includes a plurality of sealing beads including a gusset section barrier sealing bead having a first height and a protective sealing bead having a second height, the second height being smaller than the first height. The zipper sealing section includes a zipper section barrier sealing bead extending and a tapered section adjacent to the zipper section sealing bead, the tapered section tapering from a larger height adjacent to the zipper section sealing bead to a smaller height as a distance away from the zipper section sealing bead increases.

A bottom hem of a garment and a garment are provided. The bottom hem of a garment includes: a front piece of cloth having an outer side and an inner side that are opposite to each other; a dot glue layer provided on the inner side of the front piece of cloth; and a rear piece of cloth adhered to the inner side of the front piece of cloth, the rear piece of cloth being adhered to the front piece of cloth by means of the dot glue layer.

A method is described for making a retort container having one or two metal ends. A heat-sealable material is present on one or both of the container side wall and the/each metal end. The/each metal end is seamed onto the container body, and the resulting container assembly is conveyed on a conveyor adjacent to an induction sealing head and then adjacent to a cooling device. A pressure belt engages the upper end of the container assembly to keep the metal end from coming off the container body during the induction heating and cooling processes.
