A multi-phasic polymer blend for energy activated edge banding adhesion to a substrate is described. While the blend may be used for adhering edge banding to straight substrates, the blend is preferred for adhering edge banding to contoured substrates. The outer, hard, structural layer of the edge banding is formed from a polypropylene component. The polypropylene component at least includes polypropylene and an optional energy adsorber. The inner adhesion layer of the edge banding is formed from a multi-phasic polymer blend that bonds the outer layer of the edge banding to the substrate. The multi-phasic polymer blend at least includes a polyamide component, a polyolefin component, and a modified polypropylene component. Both the outer and inner layers forming the edge banding may be tinted to conform or contrast with the color of the finished substrate.

The invention relates to a method and to a device for producing a butt-welded joint between two pipe segments (38, 39) of a pipe (27, 28) made of a weldable plastic material, each pipe segment being held by a gripping means (14, 15), pipe end cross-sections of the pipe segments (38, 39) being machined with the aid of a tool means (11) for forming welding contact surfaces (40, 41), said tool means (11) being disposed in a stationary manner in a separating plane (37) for machining the welding contact surfaces (40, 41) and a separating cut for forming the pipe segments (38, 39) being realised by the gripping means (14, 15) moving the pipe (27, 28) relative to the tool means (11) in the separating plane (37), said separating cut simultaneously serving to form the welding contact surfaces (40, 41).

An apparatus for applying individual tapes in layers onto a substrate includes a plurality of reels, applicators, and a guide member. A first reel holds a first tape and a second reel holds a second tape. A first applicator includes a first pressure surface that receives the first tape from the first reel and presses the first tape in a direction toward the substrate to apply the first tape to the substrate. The second applicator includes a second pressure surface that receives the second tape from the second reel. The second pressure surface is aligned to dispense the second tape over a section of the first tape applied to the substrate and to press the second tape toward the substrate to apply the second tape over the first tape. The guide member is disposed between the reels and the applicators and aligns the first and second tapes during application.

A binding machine comprising: a feeding device for feeding a binding element (3) in the form of a wire or strap in a loop around one or more objects to be bound and subsequently retracting the binding element to draw it tightly around said objects; and a laser welding device for forming a welded joint between a section at the leading end of the binding element and an adjoining section at the trailing end of the part (3a) of the binding element fed in a loop around said objects to thereby secure this part of the binding element in a loop around the objects. The laser welding device is configured to apply an identification marking on an outer surface of the binding element by means of a laser beam (14) emitted from a laser welding head of the laser welding device.

According to one embodiment, a method of manufacturing a flexible substrate, includes forming a release layer on a glass substrate, forming an insulating base, forming a plurality of insulating layers, wiring lines and electrical elements, asking the release layer, the insulating base and the plurality of insulating layers from above to the glass substrate via a mask, forming an upper resin layer, removing the glass substrate and the release layer by peeling off an interface between the release layer and the insulating base and forming a lower resin layer so as to be in contact with a lower surface of the insulating base and a lower surface of the upper resin layer.
