Title: Improvements in machines for crimping yarns by false twist, and their parts
IPC: D02G1/02
Filed: 1958-06-20
Abstract: 874,477. Crimping yarns by false twist. SOCITEX. June 20, 1958 [June 21, 1957], No. 19821/58. Classes 120(2) and 120(3) In a machine or unit for crimping yarn by false twist comprising at least one heating device and a number of rotary spindles, each yarn passes through the heating device in a vertical or substantially vertical direction and the axis of each spindle is horizontal or approximately horizontal. In the unit shown in Fig. 1 each yarn passes from a package 1 via a guide 47 to a roller 7 and is thence guided horizontally at 46 to one of a number of tubes 2 in a multiple heating device where they are heated by an electrically-heated heat-insulated block 2b as in Specification 874,478; it then passes through a conduit 9 in a bar 8 and a guide 5 to a horizontal twist spindle 3 whence it passes via a guide 6 vertically to be wound at 4, the spindles and associated parts being arranged alternatively to left and right. A number of such units are combined together to form a machine, the spindles being driven by the upper runs of two belts, each belt passing over and under consecutive spindles, and the size of each unit being determined by the expansion of the tubes 4. The upper parts of each conduit 9 in the bar 8 are closed by a shaped member 12, Fig. 6, helping to guide the yarn to the guide 10 which is secured by bolts 11. Each guide 10 has cooling fins the work of which is assisted by air-currents generated by the belt 14, a guard 15 being shaped to draw air over the fins. Each twist spindle 13 has a head 30 with an eccentric channel 31 and a slotted nose 32 around which the yarn is wound: The spindle is mounted in a socket 29 in an eccentrically-bored elastic bushing 35 by means of which the position of the spindle relatively to the belts 14 may be changed to vary or stop the drive. The spindle may be braked by an elastic shoe 38 co-operating with wedge surfaces 41, 39; the latter may be caused to compress the shoe into varying contact with the spindle by adjusting the position of a hollow carrier 40 on a threaded part of the socket 29. A slightly different form of brake, Fig. 8 (not shown) is also described. The guides 47, 46 may act to brake and tension the yarn lightly, 47 being in the form of a hook receiving a number of turns of yarn and 46 being of Y-form, Fig. 9. The guide at 6 is in the form of a grooved roller rotating and mounted resiliently on a wire. Each roller 7 may be driven faster than the yarn travels. The yarn may be wound by a tube 18 common to a number of units which is applied either directly against the mass of yarn or, where the reels have cheeks 4a, Fig. 1, through the intermediary of a cylinder 19. A supporting girder 26 can be arranged to protect the return runs of the belts 14 and have extensions 27 to protect the unwinding from the influence of aircurrents generated by the belt. Means may be provided to stop the machine if the temperature in a heating-device falls below a certain value.
