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).

Extended melt-temp range and low energy absorptive edge banding adhesive system and edge banding

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.

SHEET SUPPLY DEVICE AND SHEET SUPPLY METHOD

Provided are a sheet supply device and a sheet supply method capable of keeping the precision of a sheet separating operation constant regardless of differences in diameter dimensions of rolls. A second guide roller is disposed at an opposite side of a standby side roll with respect to a tangential line to the outer peripheral surface of the standby side roll at a pressing position in a state in which the pressing roller is pressed against the pressing position, and guides a sheet such that the sheet is guided from the pressing roller in a direction away from the standby side roll. Furthermore, the second guide roller is fixed to a moving unit so as to be configured to approach and move away from the standby side roll together with the pressing roller.

Glue filling method for multilayer thin film sensor structure

A glue filling method for a multilayer thin film sensor structure is disclosed herein. Two outer layers of a composite heat-resistant membrane are carved to have desired patterned holes; an inner layer is interposed between two outer layers to form a layered structure. The composite heat-resistant membrane is stuck onto the multilayer thin film sensor structure with the patterned holes aligned to an electric-conduction through-hole of the multilayer thin film sensor structure to form a filling region. A conductive glue is filled into the filling region. Sustained by the inner-layer heat-resistant membrane, the conductive glue protrudes from the patterned hole to cover a portion of the conductive metals on the surface of the multilayer thin film sensor structure. Thereby are simultaneously achieved a water-proof effect, an airtight effect and a fine interface compatibility.

Tape attaching machine and tape removing method
10707104 · 2020-07-07 · ·

A tape attaching machine for attaching an adhesive tape to a frame and a wafer and cutting the adhesive tape along the frame is provided. The tape attaching machine includes a tape winding unit configured to wind a remaining part of the adhesive tape left after cutting the adhesive tape, the remaining part of the adhesive tape being not attached to the frame and the wafer. The tape winding unit includes a main shaft like a roller and a pair of jigs detachably mounted on the opposite ends of the main shaft. Each of the jigs is engageable with the main shaft so as to have a tape contact area around which the remaining part of the adhesive tape is adapted to be wound and a grip area formed axially outside the tape contact area and adapted to be gripped by an operator.

MULTI-LAYER FILM

An absorbent article includes: a first sheet-like member; a second sheet-like member; an elastic member that is inserted along a lateral direction between a pair of mutually-opposing facing surfaces of the first sheet-like member; joining portions that join the pair of mutually-opposing facing surfaces and that are spaced apart in the lateral direction; and side-seal sections that are disposed at each lateral end portion of the absorbent article. The joining portions are disposed on two sides of the elastic member in a vertical direction, which intersects the lateral direction and a front-rear direction, so that the elastic member is sandwiched and pressed between the joining portions.

Method and a device for joining ends of fiber webs in a parent roll change of an unwinder

A method for joining ends of fiber webs with a device comprising a tool element with a gripping device and a traversing punching device. A run of the fiber web from the emptying parent roll is moved to a joining position at the tool element. The trailing end of the parent roll fiber web is cut upstream from the joining position and the fiber web is attached to the tool element by a gripping device of the tool element. An end of a new roll fiber web is guided to contact with and to an overlapping position with the trailing end of the parent roll fiber. The traversing punching device is moved across the width direction of the fiber webs and makes at least one joint cut and joins the fiber webs. The new fiber web is cut downstream from the joint, and then tension control is turned on.
