Abstract

519,995. Twist tube; crimping and winding yarns. POOL. W. Oct. 10, 1938, No. 29287. [Classes 120 (ii) and 120 (iii)] A twist tube for twisting yarns &c. comprises a short hollow spindle adapted to make frictional contact with a yarn passing through it and driven by a friction wheel making external contact with the spindle which is held in engagement with the friction wheel by anti-friction means; a helically-twisted strip may be secured within the plain bore of the spindle to ensure the yarn making frictional contact with the spindle. As shown, the twist tube is used in a machine for crimping and winding yarns 25, a number of crimping and winding devices being arranged around a central shaft 6; the twist tubes 28, which are mounted in a steam chamber 2, are driven by a pair of large friction wheels 31 on the driven shaft 6, and each tube is held in engagement with the friction wheels by two pairs of overlapping anti-friction wheels 33 which engage grooves in the tube and are carried by arms 35 on a block 36 slidably mounted in a sleeve 37 and pressed by a spring 38 towards the. wheels 31; the block carries an extension 43 surrounding the tube and a spindle 39 projecting out through the chamber 2 and pivoted to a cam 41 which may be moved by a handle 42 to draw the tube out of driving engagement with the wheels 31. The tube is provided with a conical flange at its upper end and a twisted strip of metal 48 is secured in its bore to divide the bore into two helical passages, up one of which the yarn passes. Moist steam enters the chamber 2 through holes 45 and the yarn 25 is drawn from a supply bobbin 24 by a roller 22 driven from the shaft 6 and passes through a hole 26 in the bottom of a tray 27 to the tube 28; the tray collects water dripping from the hole 29 in which the tube is mounted in the bottom of the chamber 2 and the tray may be filled with water to wet the yarn before it is twisted. The yarn which has been crimped passes from the tube to a guide 50 and to a guide 77 by which it is traversed on a package 52 driven by a drum 56 geared to the shaft 6; guides 77 for diametrically opposite packages are carried from a bar 74 carrying a follower 73 engaging a cam groove 72 in a wheel 71 driven from the shaft 6. Specifications 424,880, 442,073, and 458,595 are referred to.
