  • Patent number: 4705232
    Abstract: Yarn is clamped between two rotatably mounted brake plates. The lower brake plate lies on an annular housing portion and the upper brake plate is held and centered by a guide plate. Weighting discs lie on the guide plate and are secured by a pair of clamping projections. The guide plate is displaceable on a U-shaped loop member and is prevented from rotating thereon and is itself secured by pairs of clamping projections.

  • Patent number: 4535956
    Abstract: In a housing, two rollers having substantially parallel axes are freely rotatably journaled and bound between them a clamping bite. The thread to be braked is drawn through the clamping bite and thereby drives the rollers. A first of the two rollers is stationarily mounted in the housing. The second roller comprises a cover made of a rubber-elastic material. This second roller is journaled in a pivotable forked lever which is under the action of an angle lever. The second roller can be pressed against the stationary first roller with an adjustable operating bias by means of the angle lever and a force accumulator constituted by a tension spring. Spring means of a rapid braking device constitute a compression spring supported by a braking rod which is axially displaceable between two end positions. The compression spring acts upon a spring bush carrying a nose member. In one of the two end positions of the braking rod the nose member extends with play beneath an arm of the angle lever.
