Definitions

  • the present invention is designed to achieve the same purpose with simpler means which are at the same time even more reliable the higher the speed;
  • a foot bridge mounted on the bobbin spindle and supported on opposite sides of the bobbin spindle respectively by a pair of balls running in a guide-way consisting of circular sections, is so swung lever fashion about the point of support formed by the rearmost ball for the passage of the bobbin spindle from one braiding head to the next, at the beginning of operations by a control member but during normal running chiefly by the centrifugal force of the bobbin spindle, that the forward leading ball is forced out of the one circular section of the guide-way and into the next circular section thereof.
  • Figure 1 is a vertical section and Figure 2 a horizontal section of the lower part of the machine.
  • Figure 3 is a detail showing the control of the bridge and MACHINE 504,912, and in Switzerland January 9, 1930.
  • Figure 4 is a diagrammatic plan on a smaller scale.
  • a indicates the guide plate.
  • a guide groove 1) of semicircular cross section is formed therein for the bob bin spindles, the groove forming a closed path and consisting in each braiding head of a circular section reaching to the point of transfer from one braiding head to the other.
  • a foot bridge (Z provided on each bobbin spindle 0? runs by the aid of balls 0 on opposite sides of the spindle in engage ment with the guide grooveb, being driven by rotating plates or discs h which are rotatably borne on the hollow central pillars 2' of the braiding heads and provided in their peripheries with recesses h for engaging the shanks of the bobbin spindles.
  • the plates h which serve for operating the bobbin spindles are mounted on sleeves a which are loosely mounted on the braiding head pillars a and, passing through the guide plate a, are provided at their lower ends 1Q? with toothed wheels which derive their motion from a toothed Wheel 9.
  • the latter forms with a gear w a clutch which is controlled by the bobbin threads.
  • the bobbin thread is under the action of a thread loading guard 17?. which falls down the bobbin spindle shank if the thread breaks.
  • the guard In order to overcome a tendency of the guard m to creep upwards owing to the high speed of rotation, the guard is made roof-shaped at the top and provided with ribs shaped to catch the air so as to hold the guard as low as possible by the air braking effect. If the guard on has fallen owing to a breakage of the.
  • the braid is drawn off, in known manner by a reel (not shown), which is driven from the driving wheel through a worm gear 4).
  • the lever s is extended to form a convenient handle which enables the drive to be interrupted by hand.
  • a high speed braiding machine comprising a stationary guide plate with a groove comprising circular sections, braiding heads on said plate for the braid warp threads, travelling bobbin spindles guided in said guide plate groove, rotating discs in the braiding heads for driving said bobbin spindles, a control foot bridge on each bobbin spindle, a pair of carrying balls arranged to run in said guide groove and to support said foot on opposite sides of the spindle, and controlling means so arranged as to so swing said control foot lever fashion about the point of support formed by the rearinost ball, alone at the beginning of operations and with the aid of the centrifugal force of the spindle during normal running, that the front leading ball is forced out of the one circular section of the guide-way into the next circular section thereof for the passage of the bobbin spindle from one braiding head to the next.
