Abstract: 1,008,090. Spinning and re-winding yarns. N. V. MAATSCHAPPIJ VOOR INDUSTRIELE RESEARCH EN ONTWIKKILING. Sept. 12, 1963 [Sept. 13, 1962], No. 36023/63. Headings D1D, D1F and D1J. Apparatus for spinning and doubling yarns and for re-winding the yarns so spun into large packages, comprises a spinning &c. machine, a row of dead spindles on to which packages may be transferred by hand or automatically from the spinning- spindles, and apparatus for rewinding the yarn off the dead spindles which can travel along the spinning &c. machine. The spinning machine may be of the ring-and-traveller type and comprise a row of spindles 2 on a frame 1. The dead spindles 4 are on a frame 3 movable between the position shown in Fig. 2 and one where it is level with the frame 1. With full bobbins on the spindles 4, a series of shears 6 can be operated by common means to sever the yarns between the feeding-means and the packages, the shears being of the kind which take hold of the yarn-end. The winding-apparatus comprises a winder 10 a knotter 36, suction elements 57, 58, a yarn-cutter 54 operated by an electromagnet 56, and yarn-transferring and guiding elements 18, 38, 39 and 48. The operation of all of these, and of the spinning-frame and the travel of the unit is controlled by a shaft 14, in some cases through cams 60 and switches 59. The element 18 can rotate in a vertical plane as a shaft 20 is rotated by chain and sprocket gearing from a shaft 21, which is itself rotated from shaft 14 by level-gearing and a shaft 24. The end of the member 18 has a releasable yarn-clamp constituted by a retractable member 32 and an enlarged head on the end of member 18. Member 32 is carried by two rods which can slide on member 18 as a spring-urged interconnecting part 27 engages a fixed cam 31 as the member 18 rotates. The member 48 can rotate in a horizontal plane as a cam 52 raises and lowers a rod 49. The members 38, 39 are connected to pinions 44, 45 engaging racks on sliding rods 42, 43 engaged by cams 40, 41. In operation, with the filled bobbins on the spindles 4 and the yarn ends severed and held by the shears 6, the end from the first bobbin is taken by hand or automatically out of the shears and placed in the winder. The winder is then started and continues to run until a light-sensitive device 62 detects that the yarn on the bobbin is nearly unwound. It then stops the winder and starts the motor driving the winding-unit along the spinning-frame. This continues to run until the device 62 comes opposite the next filled bobbin, whereupon it starts the drive of shaft 14. This rotates member 18, the yarn being clamped and carried in the direction of arm 63 above the knotter 36 where it is released while the member 18 continues to rotate to starting-point. The rotating shaft 14 operates the arms 38, 39 and 40 to pull the yarn from the filled package and that depending from the winder, across the knotter; the suction elements are operated so that the one at 57 holds the yarns taut; the knotter is operated; the shears 54 are operated for the several ends of the knotted yarns to pass into nozzle 57 and to cut the yarn between the winder and the nearly exhausted bobbin, the residue on the latter passing into nozzle 58. The cam-shaft motor is now deenergized and the motor of the winder restarted.
