Definitions

  • the invention relates to a yarn braking device specified in the preamble of claim 1 and claim 2.
  • the flexible second brake element defines a spring arrangement whose spring force, which generates the contact pressure of the second brake element against the first brake element, is controlled by a linear electric motor.
  • the spring force In order for the linear motor to be able to carry out the intended working stroke of its rotor, the spring force must not be greater than the respectively set maximum magnetic contact force, otherwise the linear motor could not overcome the spring force and could not execute a stroke. How the yarn braking device behaves when passing a node in the thread through the yarn braking zone between the first and second brake elements is not disclosed.
  • Known yarn braking device is provided for adjusting an initial position of the second brake element connected to the magnetic element, a return spring which acts on the magnetic armature in the direction of a stopper damping elastic part. How the yarn braking device behaves when passing a node in the thread is not disclosed.
  • the magnetic armature is a coil which is adjustable relative to rod-shaped permanent magnet and is connected to the second brake element. Between the coil and a brake shoe of the second brake element, a rubber buffer is attached. How the yarn braking device behaves when passing a node in the thread is not disclosed.
  • known yarn braking device has plate-shaped brake elements.
  • the first brake element is pressed by the second brake element with the adjustable Magnetanpresskraft against the stationary stop.

  • the Magnetanpresskraft can be changed while the thread is running and continuously.
  • the mass of the second brake element together with the mass of the magnetic armature and against the repulsive magnetic force of the magnet must be pushed away from the first braking element supported on the stationary stop. Due to the inertia of the large mass, especially the magnetic armature creates a momentary increase in thread tension, which can lead to tearing of the thread.
  • the first brake element is provided on a stationary magnetic body.
  • the second brake element is movable relative to the first brake element and is urged by the first brake element through a magnet with pulling magnetic force.
  • the second brake element is moved against the magnetic force from the first brake element away, with the decisive for the strength of the magnetic force gap width changes, even if the second brake element only tilts laterally.
  • This instantaneous enlargement of the gap width significantly reduces the magnetic force, so that the braking effect is reduced and the second braking element returns to the starting position relatively delayed after the node has passed through with a critical transient. With thick thread material, the recovery takes place very slowly and with a significant settling.
  • the first brake element is provided on a stationary magnetic body.
  • the second brake element is held in a self-movable manner in a hinged lid which engages over the magnetic body and is acted upon by the first brake element with pulling magnetic force and pressed against the first brake element.

  • the yarn braking device should be particularly suitable for thick yarn qualities.
  • the function of the yarn braking device takes into account the phenomenon that a node passing through the yarn braking zone (or a thickening) when the yarn is running at relatively high speed generates a relatively high-frequency momentary energy impact transversely to the yarn running direction.

  • the yarn braking device is equally suitable for practically all thread qualities with this design, but especially for thick thread material, which generates a considerable release movement when a knot or a thickening passes.
  • the mass of the respective brake element is designed so small that it can be displaced by the energy impact of the node, while the much larger mass of the solenoid valve does not shift under the influence of this energy impact.
  • the mass of the first spring element is displaced against the spring force at a node, while the magnetic armature with the second brake element remains at least substantially motionless.
  • the first spring element remains under spring force on the stationary stop so that it acts as a stationary braking surface for the second brake element.
  • the spring arrangement provided between the second brake element and the magnetic armature forms a mass decoupling upon passage of a node, so that the second brake element is displaced from the node against the spring force and relative to the magnetic armature with substantially immobile magnetic armature.
