Definitions

  • the invention relates to cross-winding machines with an automatically variable traverse winding length of the type in which the spool and cam drum for driving the thread guide are driven at a constant speed.
  • the object of the invention is to remove this and other disadvantages and to provide a device which causes the traverse to be automatically varied without the aid of the changing diameter of the bobbin.
  • the reciprocating movement produced in known manner by the cam drum causes a variable axial reciprocating movement to be imparted to the drum, so that during certain periods the traverse of the thread guide is uniformly shortened or lengthened, and bobbins are produced with tapering ends or of a bulging shape.
  • Fig. 1 shows one example in elevation, partly in section
  • Fig. 2 is a plan view thereof
  • Fig. 3 is a side view
  • Fig. 41- is a vertical section on the line 1-4 of Fig. 1;
  • Figs. 5 and 6 are respectively a side view and an elevation of the second example
  • Figs. 7. 8 and 9 are respectively a side view, an elevation and a vertical section of the third example. the section in Fig. 9 being on the line 99 ofFig. 8.
  • a pin with a roller 2 which engages the cam groove 3 of the drum 4, by means of which. a reciprocatory movement of the rod 1 is produced.
  • the thread guide rod 1 is linked by means of a carrier bracket 5 passing diagonally through the rod to one end of a lever 8 which is fulcrumed on the axle 6, and the other end of which is in the form of a disc 7.
  • the disc: 7 is rotatably mounted in the machine frame 100 and has on its front side a diametrical slot 9 to guide a sliding block 10. This sliding block is mounted on a screw bolt 11 (Fig.
  • a disc 23 In a concentric recess on'the rear side of the disc 7 there is mounted a disc 23 in such a manner as to be adjustable and capable of being fixed therein, and in this disc a pawl 24 is mounted on a screw 25.
  • the pawl 24 engages the ratchet teeth 28 of a disc 27 rotatably and axially movable on the pivot 27 v in the frame 100, and imparts to the disc 27 stepwise rotary motion.
  • the disc 27 has a spiral crown thread 26, which engages in a rack 29 movable in a vertical slot of the frame 100 and carrying a soft buffer disc 30.
  • the rack 29 carries a pivot 31 for the actuating lever 14 and a bent arm 32 to which one end of a spring 33 is secured while the other end thereof is suspended on the frame at- 34.
  • the object of the spring 33 is to lift the rack 29 together with the lever 14 into their original position when the rack 29 is disengaged from the spiral crown thread 26 after having been in engagement therewith.
  • On the pivot 27 is mounted a spring 35, which keeps the crown thread disc 27 in engagement with the rack 29.
  • a pin 36 is used, which abuts against the disc 27 and is adaptedto be moved by means of a twoarmed disengaging lever 37 mounted. on the frame.
  • the lever 37 can be operated by hand or automatically.
  • the mode of operation of the apparatus is as follows:
  • the cam groove 3 of the cam barrel 4 imparts to the thread guide rod the axially reciprocating motion required for constant traverse.
  • the lever 8 and disc 7 are caused to oscillate about the axle 6.
  • the sliding piece 10 Before the winding of a bobbin is started the sliding piece 10 must be adjusted and fixed in the slot 12 of the lever 14 by means of the bolt 11, and the rack 29 together with the lever 14 must be moved to their highest position by means of the spring 33.
  • the sliding piece 10 is shown in its zero position, i. e., in the position concentric with the axle 6, in which no rotary motion is transmitted from the disc 7 to the lever 1 1. If, however, the sliding piece 10 is in a posi: tion eccentric to the said axle the lever '14 is on the swinging of the disc 7.
  • the crown thread disc 27 is rotated stepwise in one direction by the pawl 2d, and moves the rack 29, downwardly together with the lever 14, so that the sliding block 10 descends in the slot 12 of the disc 7 and consequently causes a gradual increase in the stroke of the lever 14 and thus a shortening of the traverse, as the displacement due to the cam groove reduced by displacement of the cam barrel in the opposite direction.
  • the crown thread disc 27 has an annular V shaped groove e2 in which. engages an actuating eccentric 43 with a wedge-shaped edge.
  • This eccentric is carried by the arm i l: of a bell-crank lever 4:41;, 45 which i. loosely mounted on the hub of the disc 27 and the other arm of which has a surface and an fiscillation of the lever 3* and the d cs 7 and causes the roller i to engage oh. one surface the bell-crud; le 14, d5 and to t n in the direction of r it arrow T G) that the crown thr disc 2? is rotated by means of the eccentric d3.
  • the pawl 273 is loosely mounted on and the spring 1r; nxed to an arm 45 of two-armed lever 15 45 which is mounted on" the frame 1,000 and the arm 45 of which is actuated by the roller 500 in the same manner, as is the arm of the bell-crank lever +54, is operated by roller 50 in the case of the example illustrated by Figs. 5 and 6.
  • the arms d5, 4-5 are connected together by a screw i51 It may be readily seen that the screw 270 receives a step by step rotation from the roller 2 with the teeth 500 and thus acts in the same way as the crown thread disc 27
