In the cop winding apparatus illustrated in Fig. 6, yarn is wound on a rotating spindle 13 and is traversed thereon by a hook 34. Cop formation is aided by two cones 44 and 45 on a lower carriage slidable on guide rods 47, 48 that are parallel with the spindle 13. The symmetrical spacing of cones 44 and 45 about the axis of the spindle 13 is adjustable by rotation of a screw (60), Fig. 11, (not shown) and then lockable in a selected spacing by means of a locking screw (65). As the cop 3 is built up it extends more and more upwards along the spindle 13 until it surrounds the spindle 13 along its entire length and exceeds this by approximately a quarter or a third. The top of the cop 3 is engaged by a guiding cup 67 carried by a second or upper carriage 68 slidable on the rods 47, 48. When the cup 67 reaches a predetermined height pneumatic means 11 caused to move the cup 67 away from the cup and cause the cones 44, 45 to rise up and doff the cop. Doffing When the upper carriage 68 reaches a predetermined setting an abuttment 73 thereon strikes a roller 81 on a lever 82, Fig. 17, to cause a plate 84 to move against a spring 93 and actuate two miniature switches 78, 80. The setting of the switches 79, 80 is adjustable by screws 89, 90 so that one switch may operate before the other. Actuation of switch 79 stops the motor 33 driving the spindle 13. Switch 80 opens an electro magnetic valve to allow compressed air to enter a cylinder 97 and move the piston rod 98 upwardly. Upward movement of the piston rod 98 causes abutment 99 thereon to strike a yoke 52 on the carriage 46 causing the carriage 46, and therewith the cones 44 and 45, to rise from a lower position to an upper doffing position in which the cop 3 is lifted off the rotating spindle 13. Upward movement of the piston rod 98 also causes an abutment 100 carrying a pivoted hook 101, 102 to rise, the hook 101, 102 engaging the upper carriage 68 to raise it and the cup 67 upwardly, cup 67 being raised slightly before the cones 44, 45 so that the cop 3, as it is raised by the cones 44, 45, can be freed from the cup 67 and drop by gravity into a funnel or the like leading to a container or conveyor. As the piston rod 98 reaches the top of its stroke a cam operated cranked lever (113), Fig. 19 (not shown), is rocked to actuate a switch (112) that causes compressed air to be fed to the upper end of the cylinder 97 to return the piston rod 98 to its lower setting. In Fig. 9 the yarn passes from the bobbin 2, through a tube 11 that prevents ballooning, through a braking disc 14 and through a stopmotion device 15. The stop motion device 15 is a disc 24 freely rotatable on a lever 26 swingable about the pivot rod 17 of the braking disc 14. If the yarn breaks, lever 26 rocks to cause a cam 28 on lever 26 to act on lever 29, Fig. 5 of a contactor 30 in a manner stopping a motor 33 driving the winding spindle 13, Figs. 3 and 5. The stopping of the motor 33 is not completely instantaneous following the actuation of the first switch 79. By its inertia, the motor 33 performs several additional revolutions during the doffing of the cop 3 from the spindle 13. The result is that as the cop is doffed from the spindle 13 a few turns of the yarn are wound on the spindle before it stops. These turns facilitate the beginning of the formation of the new cop. To free the doffed cop from the following cop. the yarn is severed by a guillotine 118 which is upwardly displaced by the carriage 68 and operates in conjunction with fixed blade 119. During the return motion of the carriage 46, the carriage 46 actuates a fourth switch 117 that re-establishes the supply of electric current to the driving motor 33 and thus starts up the rotation of the spindle 13. The amplitude of the stroke of the hook 34 is adjustable and the winding spindle 13 is restrained from moving axially.. 1,115,631. Treating textiles.
