A pipe device includes a pipe and a connection element. The pipe has a pipe jacket that has an inner surface and an outer surface and forms a flow channel. The connection element forms a through-channel that extends from a connection piece consisting of a first material (M1) and having a first opening to a second opening. The pipe jacket is positioned on the connection piece with a first pipe end consisting of a second material (M2). A bonded connection is formed between the first material (M1) and the second material (M2) in a contact region between the inner surface of the pipe jacket and a peripheral surface of the connection piece.

A direct bonding method of metal and resin comprises a first step where the metal material is subjected to electrolytic treatment by using a carboxylic acid to form a new surface, which is then coated with the carboxylic acid to obtain a carboxylic acid-coated metal material; a second step where the resin material and the carboxylic acid-coated metal material are laminated to form an interface to be bonded; a third step where the interface is heated to Tg of the resin material or higher by heating means to remove water from the interface, the decomposition of the resin material generates a carboxyl group, and the new surface is exposed on the surface of the carboxylic acid-coated metal material by removal of the carboxylic acid; and a fourth step where the interface is cooled below the Tg to form a bonded part by bonding the carboxyl group and the new surface.

A method and apparatus for making bags with hem seals is disclosed. The machine includes an infeed section and a draw tape section. Bags are made from a film and a film path extends through the infeed section and through the draw tape section. The draw tape section includes a hem sealer that includes a stationary sealing plate on one side of the film path such that film path passes across the stationary plate. A sealing head is on the second side of the film path, opposite the first side, such that the film following the film path passes between the sealing head and the stationary plate. A sealing section may be included. The draw tape section may include driven infeed an outfeed nips.

The present invention provides a movable load bearing structure with a surface that includes antimicrobial agents capable of eliminating, preventing, retarding or minimizing the growth of microbes and also minimizing cross-contamination when the load bearing structure is being reused for cargoes that differ from a previously transported cargo, for example, different food types, such as poultry, fresh vegetables, and fresh fruit. The load bearing structure may be a dunnage platform or a container for storing and/or shipping cargo.

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.

A device for processing, in particular for ultrasound welding, of packaging sleeves and/or packagings includes at least two tools for processing, in particular for ultrasound welding, of packaging sleeves. Each tool has an operating region. The tools are supported in such a manner that there is produced between the operating regions a gap whose longitudinal direction corresponds to the transport direction of the packaging sleeves, and the tools are supported in such a manner that the size of the gap can be changed. In order also to enable continuous welding of the packaging sleeves in a reliable manner with changing material thicknesses, there is provided at least one parallel spring on which at least one of the tools is movably supported transversely relative to the transport direction of the packaging sleeves.

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 system and method for welding edge seams at the edges of fabric is presented. A method begins by lowering a fabric pre-fold bar onto a piece of fabric. A pre-aligned portion of the fabric is pushed on top of the pre-fold bar so that the pre-fold bar is between the portion of fabric on top of the fabric pre-fold bar and other fabric below the pre-fold bar. The fabric on top of the fabric pre-fold bar is folded edge fabric and fabric not on top of the fabric pre-fold bar is not folded edge fabric. A folded edge is formed between these two sections of fabric. The method pinches some of the fabric at the folded end and then pulls the folded edge fabric off of the fabric pre-fold bar. After that, the method welds at least some of the folded edge fabric to the not folded edge fabric.

Apparatus and methods are provided for creating tubular devices, e.g., as components for catheters, sheaths, and or other devices sized for introduction into a patient. In one embodiment, a method is provided for making a tubular device using a sheet of material including a coated first surface. The sheet is rolled around a mandrel until longitudinal edges of the sheet are disposed near or adjacent one another, e.g., without attaching the longitudinal edges together. A tubular braid is positioned over the sheet-wrapped mandrel, one or more tubular segments are positioned over the tubular braid, and heat shrink tubing is positioned over the tubular segments. The resulting assembly is heated to cause the tubular segments to at least partially reflow and/or otherwise laminate the tubular segments to the tubular braid and sheet. The heat shrink tubing and mandrel are then removed to create the tubular device.
