Abstract: Battery element 2 is sandwiched between and surrounded by casing films 4, 5 each having a thermo-fusing resin layer, and is sealed by thermally fused region 6 formed by thermally fusing around the overall periphery. Cross-link structure portion 13 is formed in part of thermally fused region 6 by cross-linking casing film 5, and gas release chamber 12 is formed with its leading end positioned in cross-link structure portion 13. Gas release chamber 12 is a portion which is surrounded by thermally fused region 6 along its periphery, and in which casing films 4, 5 are not thermally fused. Tube 14 which is open at both ends is connected to gas release chamber 12, while sandwiched between casing films 4, 5, with its leading end positioned in gas release chamber 12.

Abstract: The process is carried out on a spinning system that has a driven spindle (13) and a balloon limiter (14) concentric with it, driven in the same direction as the spindle (13) an provided with an inner work surface (44). For the purpose of reaching the high operating speed, the yarn (P) entrained by the work surface (44) and running toward the tube (23) on the spindle (13) is first always given by the centrifugal process the shape of a rotating, open loop (48), from which the yarn (P) is subsequently drawn off and coiled directly onto the tube (23). In this connection, this rotating, open loop (48) can be radially delimited by a rotating or stationary limit ring (28).

Abstract: An arrangement is disclosed for pneumatic false-twist spinning having a drafting roller device, at least two air nozzles that are arranged behind one another in the travel direction of the yarn, a yarn withdrawal device and means for the transfer of the movably held air nozzles from an operating position following a pair of delivery rollers of the drafting roller device into a piecing position that is offset with respect to the pair of delivery rollers. It is provided that a movably held suction tube is assigned to the drafting roller device, the suction tube, by means of an adjusting device, is able to be applied to the pair of delivery rollers of the drafting roller device when the air nozzles are moved out of the operating position.

Abstract: Method and apparatus for splicing two textile yarn ends by untwisting the end portions of each to form a spread beard thereof, interpenetrating or intertwining the beards at both ends, and letting the twist accumulated at both ends progress towards the two mutually interwined or interpenetrated beards.In the method, the untwisted end portions of both yarns are subjected to an axial traction force to set the beards of both yarn ends free and to separate and set the beard fibers substantially parallel with one another, while the beard bases are secured to retain the individual torsion or twist of the fibers, with the beards then being moved laterally to arrange the same adjacent to one another at zones of the beard bases, while the beards are simultaneously slided in longitudinal relative movement to one another.

Abstract: In a method for splicing filaments, respective end portions of two filaments are held in overlapping condition in a holding device comprising two axially spaced rubber holders, each holder having a radial slot for receiving and retaining the overlapped end portions. One of the holders is rotated relative to the other to twist together the overlapping end portions. The holders are then fixed against relative rotation, and the twisted together end portions are fused together to form a splice of substantially circular cross-section. The method and device are useful for splicing plastic coated glass yarn used to reinforce telecommunications cables.
