Abstract

367,495. Bobbin-winding apparatus particularly for use in spinning artificial filaments. PARCOFIL AKT.-GES., 20, Peterstrasse, Zurich, Switzerland.-(Assignees of Ruka Ges. f³r Patentverwertung; 10, Neumuhlequai, Zurich, Switzerland.) Dec. 18, 1930, No. 38215. Convention date, Dec. 19, 1929. [Class 120 (ii).] In bobbin-winding apparatus for winding at a constant winding-speed and with a variable traverse, particularly for use with spinning- machines for artificial filaments, ratchet mechanism operated from the traverse cam shaft effects an adjustment of the length of the traverse and of the speed of the winding-spindle in accordance with the growth of the bobbin, and also effects the rotation of the bobbin carrier to bring a fresh bobbin into the winding- position when one is fully wound, the traverse guide and the spindle drive being at the same time returned to their initial positions. The traverse may be increased or reduced during winding so as to wind bobbins with internally or externally coned ends. The spindle-driving shaft 1 is driven through friction discs 2, 3 from a shaft 4 and drives a shaft 7 carrying a swash plate 8, a member 9, mounted on a shaft 10 and connected to a rod 91 slidably mounted in the shaft and carrying a guide 21, engaging the swash plate. The shaft 10 is slowly rotated by adjustable ratchet and worm gearing 31, 32 actuated from the shaft 7, so as to adjust the position of the member 9 relative to the swash plate to vary the traverse, the friction disc 3 being simultaneously moved by crank mechanism 16 on the shaft 10 to vary the speed of the spindle-driving shaft 1. A cam 56, Fig. 4, on the shaft 33 of the worm 32 is arranged so that, when a bobbin is fully wound, it raises a rod 57 and thereby releases a pawl 52 on a plate 50 which thereupon engages a ratchet wheel 51 on a shaft 46 driven from the shaft 7. The shaft 43 is thereby driven through the plate 50 and gears 47, 44 and the bobbincarrying plate 75 rotated to remove the full bobbin and bring an empty bobbin into gear with the wheel 70 on the shaft 1. A cam 63 on the shaft 43 releases a retaining pin 74 on the carrier, and, at the same time, moves a lever 65 which disconnects a clutch 69 on the shaft 10, so that springs 12, previously stressed during its movement, restore the shaft 10 to its original position thereby resetting the traverse and the spindle-driving gear. The Specification as open to inspection under Sect. 91 (3) (a) comprises also an arrangement of pinions and quadrants adapted to block themselves after half a turn as an alternative to the pawl and. plate mechanism described above for controlling the rotation of the bobbin-carrying plate. This subject-matter does not appear in the Specification as accepted.
