Definitions

  • the invention relates to a yarn brake specified in the preamble of claim 1. Art.
  • the cover is lifted by two links against spring force to the yarn path perpendicular to the fixed braking surface and parallel axes parallel to itself slightly from the fixed braking surface. Since the cover in the raised position covers the braking zone, neither free access nor unobstructed view are possible.
  • the lamella is fixed to an axis which is non-rotatably fixed in the housing and pretensioned against the fixed braking surface. The braking zone can not be exposed.
  • the cover can be slightly adjusted by means of two C-shaped links around adjusting axes which are parallel to the fixed braking surface. Since the braking zone is not completely exposed, neither unhindered access nor free viewing are possible.
  • the thread brake is equipped on the lid or on the brake housing with a compressed air cleaning system, which directs transverse to the thread running direction air jets in the braking zone
  • the invention has for its object to provide a yarn brake of the type mentioned above, which is dictated by the practice requirements for rapidly produced, unobstructed access or insight to or in the braking zone and / or compressed air cleaning in a structurally simple way.
  • the hinged lid which can be hinged on one side, not only lifts off the braking surface when opening, but also moves away from the fixed braking surface with its cantilevered end section. As a result, the braking zone is completely exposed and are given both unobstructed access to and full view of the braking zone. That is, the fixed braking surface and its surroundings are just as accessible as the brake plate and its surroundings on the hinged lid.
  • the hinged lid can be opened and closed quickly, so that no significant downtime of the peripheral devices of the yarn brake is necessary for a control or the like. The handling is extremely convenient. The structural complexity for this comfort function is low.
  • the adjusting axis is approximately parallel and with respect to the fixed braking surface laterally offset from the yarn path.
  • the hinged lid pivots upwards and sideways completely out of the braking zone. Access to the braking zone is possible from all sides, especially from above.
  • the adjusting axis can be arranged at least approximately parallel to the braking surface and approximately perpendicular to the thread running path.
  • the opened hinged lid releases the entire braking zone.
  • the positioning axis is also offset to the thread running path. e.g. to the top, then there are even more convenient accessibility.
  • the adjusting axis may be arranged on the inlet side or on the outlet side of the fixed braking surface.
  • the adjusting axis is designed as a hinged lid hinged hinge in the housing.

  • the hinged lid shields in the Close the brake zone to the outside. When the hinged lid is open, the entire braking zone is freely accessible.

  • High ease of use allows a positioning at least for the closing and / or the Aufklapplage the hinged lid.
  • the opened hinged lid does not need to be held. In the closed position, it has the position that is favorable for the correct working of the brake disc.
  • the brake disk may have open Ein von bainitese to their Leksrändem, in which engage the pin anchors.
  • the open Ein von bainitese are manufacturing technically expedient and facilitate the replacement of the brake disc, because the purpose appropriately thickened heads having pin anchors need not be dismantled.
  • At least one spring can be provided between the underside of the hinged lid and the brake disk.

  • the throttle gap is so small, that just no contact between the brake disk and the wall can enter, but on the other hand, as little compressed air as possible can flow out unused to the outside. Thanks to the throttle gap, a predominant part of the compressed air acts on the braking zone, so that with low compressed air use effective removal of even critical impurities is achieved.
