Definitions

  • each thread is held by means of a brake as it exits the warping gate in order to apply it to the warping beam with a uniform pull.
  • Braking of this type is undesirable in fast-running warping systems, since the resistors on the guides of the thread to the warping beam already give the thread sufficient tension.
  • a brake would also cause the threads to become too tight in these fast-running warping systems.
  • it is necessary to brake the fast-running thread to avoid re-shooting the threads when the warping machine z. B. must suddenly be stopped or braked because of a yarn error.
  • clamping brakes for each thread have therefore been provided, which are actuated mechanically, ie switched on when the warping arm rotation is switched off, brought into the braking position, and released again when or after starting the warping tree.
  • the operating mechanism is very slow and difficult to use due to the large number of thread brakes on the warping system.
  • a plate thread brake which can be switched on or off by means of compressed gas, usually compressed air against gravity or spring force, is used as the clamping brake for each thread of a warping system.
  • compressed gas usually compressed air against gravity or spring force
  • a plate thread brake which particularly meets the requirements outlined above, consists of a housing that supports the saucer and contains the gas supply to a system that can be expanded by gas pressure, and a body that is axially movable in the housing and that is non-positively connected to the system that can be expanded by gas pressure, and has a mandrel supporting the top plate. If the gas pressure inside the expandable system is increased, the mandrel carrying the upper plate moves upwards against the force of gravity due to the expansion of the expandable system, thereby lifting the upper plate from the lower plate and thus releasing the clamping brake.
  • the strength of the braking effect is determined by the surface condition of the upper and lower plates, but especially by the pressure of the upper plate on the saucer. This pressure can e.g. B. generated by springs.
  • the pressure can be varied in an easily reproducible manner by means of top plates of different weights or by additional weights.
  • the times for the plate thread brake to respond can be reduced by springs which counteract the expansion of the system. Springs also enable a different switching of the plate brake, in which the top plate is lifted off the bottom plate without compressed gas and the pressure of the gas lowers the top plate onto the bottom plate. As a result, a particularly rapid application of the braking effect is achieved when the skiving tree rotation is turned off.
  • a metal can with an elastic lid - similar to the cans used in aneroid barometers, but without an internal compression spring - and with compressed air connection or two plastic foils glued together at the edges with a compressed gas supply between the two foils.
  • a system consisting of cylinder and piston is preferred, wherein the compressed gas can be routed both through the piston and directly into the cylinder.
  • the piston is firmly connected to the housing while the cylinder is on or in the movable body.
  • the thread should not be decelerated by the brake when it is open.
  • Figure 1 shows the plate thread brake according to the invention in plan view with the top plate removed.
  • the saucer 11 is held by the outer ring 2 on the housing 1.
  • the thread 3 runs through the slot of the mandrel 4.
  • Figure 2 shows a vertical section through the thread brake.
  • the piston 7 with mandrel 4 is located in the housing 1 with gas supply 5 and cylinder 6. If compressed gas is fed into cylinder 6 via the compressed gas connection 5, the piston 7 with mandrel 4 moves upwards; the upper plate 12 sits on the shoulder of the mandrel and is lifted off the lower plate 11.
  • Springs, e.g. B. compression springs between the housing 1 and piston 7 can be provided to accelerate the lowering of the mandrel 4 with the upper plate 12 after switching off the compressed gas supply and opening an outflow valve.
  • FIGS. 3 and 4 show a plate thread brake which, as shown in FIG. 4, is opened without compressed gas and closes by gas pressure (see FIG. 3).
  • the cylinder 6 with compressed gas supply 5 is fixed to the housing 1, the piston 7 via the lower centering plate 8 ⁇ , the connector 9 and the upper centering plate 8 with the Mandrel 4 connected, which carries the upper plate 12 on his shoulder.
  • the opening of the brake is effected by the springs 10 between the housing 1 and the upper centering plate 8.
