Abstract: A false-twist texturing method and apparatus wherein synthetic filaments are drawn in a draw zone, passed from said draw zone to feed means for feeding the drawn yarn at a speed lower than the speed in the draw zone to a texturing zone wherein the yarn is texturized.

Abstract: In a textile machine provided with a doffing and donning apparatus utilizing a conveyer belt for temporarily supporting full size yarn packages doffed from the textile machine and carrying the yarn packages outside the textile machine and for temporarily supporting fresh bobbins supplied from a fresh bobbin supply device mounted on an outend frame of the textile machine, a method and device for transferring fresh bobbins from the bobbin supply device to the respective pegs of the conveyer belt when the conveyer belt is driven before starting the donning operation. When the conveyer belt is driven so as to pick up the fresh bobbins by the respective pegs, each peg is inserted into the bottom bore of the corresponding fresh bobbin in such a way that the head of the peg approaches the bottom bore of the fresh bobbin along a passage inclined to a plane along which the fresh bobbins are supported.

Abstract: A spinning, twisting or spooling machine, especially a draw-twisting machine, wherein the various thread transport rollers are driven by individual electric drive motors, and wherein electric switches and circuitry are provided for the time-staggered actuation of selected sub-groups of drive motors.

Abstract: A cable stranding apparatus wherein back tension on wires drawn from spools thereof and helically wound around a central core is controlled by positive drive means controlling the speed of rotation of each spool about its own axis in a controlled proportion to the speed of rotation of the central shaft of such apparatus about its axis. This controlling of the speed of rotation of each spool about its axis is varied during operation of the apparatus in response to means sensing the back tension on at least one of the spool wires. As a result, the back tension on the wire from the spool controls the speed of spool rotation, and thus frees the wire from the effects of frictional problems at high speeds, and from the effects of variations of outer diameter of the wire on the spool as the wire is progressively unwound from the spool.

Abstract: False twisting device for producing crimped filamentary yarns by introducing the filament into a cylindrical hollow of a hollow spindle, winding it around a twisting pin mounted transversely in the cylindrical hollow and taking out the filament therefrom, wherein a center point of the minimum diameter portion of the twisting pin is displaced from a rotational center axis of the hollow spindle, both in the vertical and parallel directions as related to the axial line of the twisting pin respectively, so that the filament rotated together with the hollow spindle therein is positioned concentrically with the rotating center of the hollow spindle.Said hollow spindle is mounted in a housing and supported by air bearings and it is rotated by applying compressed air to turbine blades which is provided on the circumference of the cylindrical hollow.

Abstract: Friction false twist device is of the class comprising three parallel equiangularly spaced shafts each having a set of equally axially spaced friction discs, the discs of the sets being arranged so that they overlap substantially when viewed axially and a strand passing through the centre of the device follows a zig-zag spiralling path from one disc rim to the next. The improvement comprises having one set of discs as a datum set with its shaft fixed to a support member with a flat reference surface from which the shaft projects. The two other shafts are carried on respective pivotal arms each with a flat undersurface seated on the flat reference surface of the support and the distance between the shaft axis and a pivot axis of the arm is the same for both shafts. The pivot axes of the two arms are equally spaced from each other and from the shaft axis of the datum set of discs, so that the distances between the latter axis and the axes of the two other shafts can be adjusted while keeping equal spacings.

Abstract: A method for manufacturing a textured synthetic multifilament yarn having alternately grouped S and Z twists. The textured yarn is produced by a conventional false-twist operation under a processing temperature between a softening point and a melting point of the material yarn in a first step and then the above-mentioned yarn is subjected to a process for separating individual filaments in each of the compact portions under tension.
