摘要： The aim of the invention is to produce reasonably-priced, top-quality twisting disks for false twisting of textile threads by carefully selecting the material and by virtue of the design of the hub and collar. The chosen material is a composite material, especially polyurethane, consisting of PPDI and polycarbonate and preferably filled with aramid. The hub is produced from hard PTU. This has two advantages. The collar material must meet extremely tough requirements and is the most expensive of all. It can be used in small amounts in an optimum manner, geared towards twisting. The inventive concept enables both functional parts - hub and collar - to be manufactured in a single-step or two-step injection moulding process.

摘要： Apparatus for twisting a travelling strand comprises a rotary structure (12) rotatable about a rotational axis X-X and a series of pulleys (48, 50, 52, 54 and 56) mounted on structure (12) in an array disposed about the rotational axis X-X with each pulley in the series rotatably mounted on structure (12) for rotation about an individual axis of pulley rotation which is generally parallel to the axis X-X and moves around that axis on rotation of the structure (12). An input strand guide pulley (60) guides an input strand to be twisted into a path in which it will successively engage the pulleys (48, 50, 52, 54 and 56) and a strand exit guide pulley (62) guides the strand from that path into an exit path along the axis X-X. Rotary structure (12) is driven through a drive shaft (16) and the pulleys (48, 50, 52, 54 and 56) are rotated by gearing (32).

摘要： A frictional false twister is disclosed. The twister has a plurality of rotating friction plates located between the nip of the front rollers and the yarn guide. The friction plates are staggeringly arranged for rubbing a twisted yarn. The spinning direction of the twisted yarn is opposite to the rotating direction of the friction plates. Through the action of the frictional false twister, the twist of the yarn between the false twisting device to the front nip can be increased, shortening the twisting triangle height, and increasing the spinning strength. As the yarn and the outer surface of the friction plate make relative sliding and rubbing, the friction damping force correspondingly reduces the spinning tension in the twisting triangle.

摘要： A twist generator for a running fiber aggregate possesses two friction discs rotating in opposite directions and having end faces turned towards one another for the twisting of the fiber aggregate running between the friction discs. One friction disc is made flexible and is pressed by pressure rollers towards the end face of the other friction disc and consequently against the fiber aggregate. To allow defined conditions to be obtained as regards pressing force, there are two pressure rollers, of which one is arranged shortly before and the other shortly after the thread contact point of the friction discs in the direction of movement of the flexible friction disc. The two pressure rollers are mounted next to one another, but preferably offset in the direction of movement of the fiber aggregate, on a carrier which is pivotably fastened to a spring-loaded lever. The distribution of the pressing force to the two pressure rollers can be changed by adjusting the carrier relative to this lever.

摘要： A yarn false twisting apparatus is disclosed which comprises a pair of rotating circular discs having cooperating friction surfaces for engaging a running yarn at a twisting zone. The drive system for the discs includes a drive component which includes a drive whorl and a coaxial drive pulley, and which is adapted to engage two separate drive belts. The drive component includes a unitary tubular drive member, a central shaft extending through and fixed to the drive member, a sleeve mounted to the frame of the apparatus and extending between the shaft and drive member, and bearings positioned between the shaft and sleeve. Also, the drive component is mounted to the frame by an arrangement which permits adjustment of the rotational axis of the drive whorl about a second axis which perpendicularly intersects the rotational axis, so as to permit accurate alignment of the rotational axis of the whorl along a direction perpendicular to the running direction of the tangential drive belt. The discs are mounted to the frame by a bearing assembly which includes a tubular sleeve which is releasably mounted to the frame, a rotational shaft extending coaxially through the sleeve and mounting the disc at one end, and bearings positioned between the shaft and sleeve.

摘要： A yarn false twisting method and apparatus is disclosed, and which includes a pair of oppositely rotating friction discs which are mounted with opposing faces to define a twisting zone therebetween. The yarn is advanced through the twisting zone to impart twist to the yarn in one direction, and the advancing yarn is deflected downstream of the discs so that the yarn is brought into frictional contact with the peripheral edge of one of the discs, to thereby impart an opposite twist to the yarn. The invention is useful in that it permits increased running speed and twist level, and the resulting yarn may be characterized by reduced instances of "tight spots" and less fuzziness resulting from filament breaks.

摘要： A yarn false twisting apparatus is disclosed which comprises a flexible disc mounted for rotation with a cooperating rigid disc to define a twisting zone therebetween. A pressure applying member is positioned adjacent the back face of the flexible disc for biasing the disc toward the rigid disc locally at the twisting zone so as to firmly engage the yarn passing through the twisting zone. The flexible disc comprises a hub portion disposed adjacent the center of the disc, an annular ring disposed concentrically about the hub portion and including a yarn engaging friction surface on one face thereof, and a distinct and highly flexible junction portion joining the hub portion and annular ring. The highly flexible junction portion permits the annular ring to readily flex in the lateral direction, to thereby permit the deflecting force to be minimized, while still permitting the rotating torque to be transmitted to the annular ring without significant circumferential deformation. The annular ring may also be divided into segments by radial or circumferential slots, to further reduce its resistance to the lateral deforming force of the pressure applying member, and to provide a substantially linear contact with the running yarn.

摘要： A method and apparatus for twisting a yarn, such as a sliver of staple fibers, is disclosed, and wherein the yarn is advanced through a drafting zone and then through a twisting apparatus. The twisting apparatus includes two circular discs, with at least one of the discs being flexible. Also, in the preferred embodiment, two separate pressure applying members are mounted adjacent the back surface of the flexible disc, with the members being positioned on opposite sides of the plane defined by the axes of rotation of the discs. The two pressure applying members are adapted to be actuated concurrently, with one member defining a first twisting zone wherein S twist is imparted to the advancing yarn, and the other member defines a second twisting zone wherein Z twist is imparted. Means are also provided for controlling the degree of twist imparted at each of the zones, so as to obtain, for example, a twisted yarn composed of core fibers having minimal twist and which are bound by outer fibers of greater twist.
