A system and method for forming a seam in at least one piece of material used to form an inflatable product utilizes a seam forming member that is attached to an inside wall of a piece of product material that comprises the inflatable product. The inflatable product is comprised of one or more pieces of product material and one or more seam forming members located at any location where a seam is necessary. A first portion of the seam forming member attaches to a first edge of a first piece of product material and a second portion of the seam forming member attaches proximate a second edge of the first piece of product material. The seal forming means can be accomplished by radio frequency, ultrasonic, heat or other types of welding, and adhesive or chemical based bonding.

A simplified method for making an impermeable joining on three-layer or bi-layer fabric materials, either with or without a complex construction on a joining side thereof, and being preliminarily joined by a stitching or ultrasound joining arrangement, wherein the method comprises only two method steps, a first joining step of joining two fabric material panels and a second impermeabilizing step carried out by cauterizing and sealing a strip element, and being performed by a single machine in a single operation thereof.

A method for manufacturing tubular bodies (1) exhibiting an inner circumferential surface (8) and outer circumferential surface (7) for packaging tubes out of a strip-shaped film substrate (2), which exhibits at least one weldable plastic layer (3) or consists of the latter, and which encompasses a first edge face (5) extending in the longitudinal direction of the film substrate (2) or a second edge face (6) spaced apart from the first edge face (5) by the width of the film substrate (2), wherein the first edge face (5) runs at a first angle (α) relative to a first thickness extension direction on a first radially innermost border (9) of the first edge face (5), and the second edge face (6) runs at a second angle (β) relative to a second thickness extension direction on a second radially outermost border of the second edge face (6), and wherein the first and second edge faces (6) are placed opposite each other and joined together during exposure to heat, wherein the first angle (α) and second angle (β) differ in size, in that the selected first angle (α) is smaller than the second angle (β) by an angular difference of between 3° and 70°, and that the edge faces (5, 6) are situated in such a way that an outwardly open longitudinal gap (11) is delimited by the first and second edge faces (5, 6).

A sterile connection device includes first and second carriages. The first carriage defines a first portion of a proximal slot and a first portion of a distal slot, while the second carriage defines second portions of the proximal and distal slots. A controller executes a sterile connection procedure in which a solid cutting blade is heated, followed by the heated blade being moved to a cutting position to cut sealed proximal and distal tubes received by the slots. The second carriage moves proximally or distally with respect to the first carriage so as to align the cut ends of the tubes. The heated blade then moves out of the cutting position, followed by the first carriage moving toward the second carriage so as to press the cut ends of the tubes into contact with each other so as to sterilely connect the cut ends and define a joined tube.

The invention relates to a modification process for modifying a biaxially oriented pipe, comprising a) providing a biaxially oriented pipe made by stretching a tube made of a thermoplastic polymer composition in the axial direction and in the peripheral direction, b) placing an insert within an end portion of the pipe, wherein the outer periphery of the cross section of the insert substantially matches the inner periphery of the cross section of the pipe and c) heating the end portion such that the end portion axially shrinks while the inner periphery of the cross section of the end portion is substantially maintained, to obtain a modified biaxially oriented pipe with a thickened end portion.

Provided is a molded article which contains a first enclosure; a second enclosure adjoined with the first enclosure; and a transparent member held by the second enclosure, each of the first enclosure and the second enclosure being independently made from a resin composition that contains a polyamide resin having a semi-crystallization time of 10 to 60 seconds, and a melting point of 200 to 280° C., and the transparent member having a pencil hardness of 8H or larger, and a linear expansion coefficient of 1×10.sup.−6 to 9×10.sup.−6/° C., where the semi-crystallization time means a time measured by depolarization photometry at a temperature 20° C. higher than the melting point of the polyamide resin, for a melting time of polyamide resin of 5 minutes, and at a temperature of crystallization bath of 150° C.

A method of directly joining a polymer to a metal along a joint interface through the formation of C—O-M chemical bonds, where M represents an element in the metal to be joined. The method includes heating the metal to a predetermined temperature above a glass transition temperature of the polymer and less than a flash ignition temperature of the polymer and less than a metal melting temperature of the metal; physically contacting at least one of the metal and the polymer; and applying compression pressure to the joint interface of the metal and the polymer when the metal is above the glass transition temperature of the polymer and less than the flash ignition temperature of the polymer and less than the metal melting temperature of the metal to generate intimate atomic contact between the metal and the polymer to create C—O-M chemical bonds between the metal and the polymer.

The disclosure relates to a pipe joint applicator with a control device and a method for producing a joint between a first pipe element and a second pipe element. The pipe joint applicator with a control device thereby detects actual process parameters via means for actual value detecting. The pipe joint applicator with a control device and the method determines therefrom the target process parameters for process control means for controlling the process parameters to be delivered to a pipe joint to be made. The pipe joint applicator with a control device optionally compares at least one actual value of the process parameters to at least one target process parameter and, in the event of deviation from at least one tolerance value range, issues an alarm to the user and/or generates an error protocol.

A plastic component with a substrate including a plastic and at least one first fastening piece that is embodied for a form-fitting engagement with a complementarily formed second fastening piece and has at least one anchoring element embedded and fixed in a position in the substrate; the substrate includes soft foam with a weight per unit volume of 120 kg/m3 to 300 kg/m3 and a Shore A hardness of 5 to 100 and the fastening element includes a thermoplastic plastic.
