Peelable seals including porous inserts are described. An example peelable seal includes a porous insert positioned between a first sheet and a second sheet. The porous insert includes a plurality of interwoven strands and a plurality of pores adjacent the interwoven strands through which a bond is formed between the first sheet and the second sheet when heat is applied to at least one of the first sheet, the second sheet or the porous insert.

A profile body of a not liquefiable material is used as a connecting element between a first object and a second object. The profile body may especially be metallic and/or may be bendable. The profile body, in contrast to a conventional wire, however, has a shape defining a first and a second undercut. The method includes embedding the profile body in the second object so that the second undercut is within material of the second object, and embedding the profile body within material of the first object so that the first undercut is within the first object, and wherein at least embedding of the profile body in the first object is caused by mechanical energy impinging on the first object and/or on the second object while the first object and the second object are pressed against each other.

A method includes rotating a drum about an axis and an anvil roll about an axis of rotation. The drum includes a fluid nozzle and a press member, the press member having an outer surface. The anvil roll includes a compliant outer circumferential surface. One or more substrates are advanced in a machine direction onto the drum. The fluid nozzle moves radially outward and a jet of heated fluid may be directed onto the substrates. The fluid nozzle retracts radially inward and the press member may be shifted radially outward. The substrates may be compressed between the press member and the anvil roll such that the press member deforms the compliant outer circumferential surface of the anvil roll.

The invention relates to an induction connection sleeve (1) for fusion joining of plastic pipes (2, 3). The induction connection sleeve (1) comprises a sleeve body (9) having a first (5) and a second receiving portion (7) for receiving first (4) and second connection portions (6) of the plastic pipes (2, 3) to be connected, a first induction heating element (12) and a second induction heating element (13). The sleeve body (9) comprises an inner part (10), which inner part (10) forms the two receiving portions (5, 7) and on which the induction heating elements (12, 13) are accommodated in such a way that the recesses (16) of the induction heating elements (12) are penetrated by the inner part (10) and are flush at their outer lateral surfaces (14, 15) with the inner part (10) in the area of the induction heating elements (12, 13). The sleeve body (9) further comprises an outer part (11) which is connected to the inner part (10) in a bonded manner and surrounds the outer lateral surfaces (14, 15) of the induction heating elements (12, 13).

The present disclosure provides a process. In an embodiment, the process includes A. providing a fitment with a base, the base comprising an ethylene/-olefin multi-block copolymer; B. placing the base between two opposing multilayer films, each multilayer film having a respective seal layer comprising an olefin-based polymer; C. flat sealing the base to each multilayer film with opposing heated flat seal bars, the flat sealing forming opposing seal joints at the flattened base ends; and D. point sealing the opposing seal joints with opposing curved seal bars.

Provided is a thermoplastic resin film laminate, which is obtained by ultrasonic welding of a thermoplastic resin film and a thermoplastic resin molded article, and which has high welding strength and excellent appearance with less welding marks. The above-described problem is solved by a thermoplastic resin film laminate which is obtained by bonding, by ultrasonic welding, a thermoplastic resin film having a thickness of 0.4 mm or less and a welding margin of a thermoplastic resin molded article having the welding margin and having a thickness of 0.5 mm or more, and wherein the height of the welding margin is 75-125% of the thickness of the thermoplastic resin film.

The present disclosure provides a process for producing a flexible container. In an embodiment, the process includes (A) providing a flexible container. The flexible container has (i) a body, and (ii) a neck. The process includes (B) positioning a fitment into the neck. The fitment has a top portion and a base. The fitment is composed of a polymeric material. The process includes (C) inserting a mandrel into the fitment. The mandrel includes an expandable collar composed of an elastomeric material. The process includes (D) expanding the collar radially outward to contact an inner surface of the base. The process includes (E) sealing, with a pair of opposing seal bars, the base to the neck.

A method of bonding together a first object and a second object having a flat part and an opening defining a contour is provided. The second object has a fastening portion having a coupling structure defining an undercut and running around a periphery of the opening. The method includes positioning the first object relative to the second object in the opening, and providing a thermoplastic material along the contour, causing a relative force between the second and first objects and impinging the assembly of the first and second object with mechanical vibration until at least a flow portion of the thermoplastic material becomes flowable and flows into the coupling structure, and causing the thermoplastic material to re-solidify.

An external thermal heat-stake arrangement includes a polymeric base member having a collared heat-stake having an inner diameter and a second member disposed within the inner diameter of the collared heat-stake. The collared heat-stake is operatively configured to be deformed by a heated element to retain at least a portion of a peripheral edge of the second member to the polymeric base member.

Described are methods for the manufacture of sporting goods, in particular a shoe, sporting goods manufactured by such methods, for example a shoe, as well as a device for performing such methods. The method for the manufacture of sporting goods, in particular a shoe, is provided, wherein the sporting goods has a first component with a first connection surface and a second component with a second connection surface. The method includes activating at least one portion of the first connection surface by providing heat energy without contact, and connecting the first component with the second component by joining the first connection surface and the second connection surface.
