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.

The invention relates to a method for producing a test body (30) for mechanically destructively testing a materially bonded joining connection, wherein the method comprises the following steps: providing an areal fiber composite substrate formed from a fiber composite material which has a fiber material and matrix material in which the fiber material is embedded, applying at least one test fabric and an adhesive to a substrate surface of the areal fiber composite substrate, and curing the adhesive, and therefore a materially bonded joining connection is produced between the test fabric and the substrate surface by way of the cured adhesive,
wherein a Dutch-weave fabric and/or a square-mesh fabric is provided as the test fabric.

A method for joining incompatible materials is provided that includes the steps of welding a first component formed of a thermoplastic material and a second component of a porous material to one another to form a subassembly and optionally molding a third component around the subassembly. The method enables the incompatible first component and the third component to be joined to one another, such as to form an electrolyte battery flow frame around an ion exchange material and/or microporous separator material in order to form a separator for an electrolyte flow battery.

Disclosed are a thermoplastic elastomer composition and a composite molded body. Specifically disclosed is a thermoplastic elastomer composition containing the following component (A1), component (B1) and component (C1). Component (A1): 70-90% by weight of a propylene polymer unit (1) obtained in a first step by polymerizing a monomer mainly composed of propylene, and an ethylene copolymer unit obtained in a second step by copolymerizing ethylene with propylene and/or an -olefin having 4 or more carbon atoms Component (B1): an ethylene-propylene copolymer rubber having a Mooney viscosity (ML.sub.1+4, 125 C.) of 20-100 and a weight ratio between the monomer unit derived from ethylene and the monomer unit derived from propylene of from 30/70 to 75/25 Component (C1): an ethylene copolymer as a copolymer of ethylene and an -olefin having 4 or more carbon atoms.

An object of the present invention is to provide a thin volume hologram sheet to be embedded sufficiently resistant to a mechanical stress such as a stress including a tensile stress, a shear stress and a compression stress at the time of processing even under a heating condition, a forgery prevention paper and a card using the same. The object is achieved by providing a volume hologram sheet to be embedded comprising a volume hologram layer, and a substrate disposed only on one side surface of the volume hologram layer using an adhesion means, wherein a peeling strength of the volume hologram layer and the substrate is 25 gf/25 mm or more.

A compound heat seal structure that, when heat-sealing a bag with a stacked area level difference, reliably seals even a section having different level and that can be easily opened. A compound heat seal structure is provided as a peelable seal in a band shape on a bag and a linear heat seal is added as a peelable seal in that band-shaped peelable heat seal in the longitudinal direction thereof.

A part has separator layers of resin laminated on each other with heat-resistant layers interposed among them and a sheath (laminated sheet) laid on each side of the laminated separator layers. The part is held, pressurized, and vibrated by a pressure vibrator and a jig receiver. The pressure vibrator and jig receiver are provided with projections that pressurize, vibrate, and break the heat-resistant layers, thereby melting and welding together the resin of the separator layers at the broken part.

Methods and apparatuses for bonding polymeric parts are disclosed. Specifically, in one embodiment, the polymeric parts are bonded by plastically deforming them against each other while they are below the glass transition temperatures. A method includes: placing a first polymeric part in contact with a second polymeric part; and plastically deforming the first polymeric part and the second polymeric part against each other to bond the first polymeric part to the second polymeric part. Additionally, during the plastic deformation, a temperature of the first polymeric part is less than a glass transition temperature of the first polymeric part and a temperature of the second polymeric part is less than a glass transition temperature of the second polymeric part.

A resin-rich peel ply that does not leave behind residual fibers after peeling and can work well with different resin-based composite substrates. The resin-rich peel ply is composed of a woven fabric impregnated with a resin matrix different from the resin matrix of the composite substrate. The peel ply is designed such that, upon manual removal of the peel ply from the composite substrate's surface, a thin film of the peel ply resin remains on the composite substrate's surface to create a bondable surface capable of bonding with another composite substrate, but no fibrous material from the woven fabric remains on the same surface.

A process for welding profiles (1) of a thermoplastic or thermoplastic elastomer to a top layer (3) of a belt (2), such as a conveyor belt, also being made of a thermoplastic or thermoplastic elastomer. The process uses thermal impulse welding and applies the welding heat onto the surface (21) of the belt (2) which is opposite to the top layer (3). The process is in particular suited for welding TPO profiles to TPO top layers.
