Description

Be specially adapted to the thread brake of weaving machine yarn guide
The present invention relates to a kind of thread brake that is specially adapted to weaving machine yarn guide.
More specifically say, thread brake involved in the present invention acts on the free end of a thread-carrier yarn storage cylinder with rounding/circular unwinding wheel rim, and brake body with a frustoconical, this brake body is made by deformable material diametrically, and having an in-to-in continuous brake area on circumference, described brake body is supported in the fixing holding device; Also have a spring assembly that is made of the discrete spring tongue piece that distributes on circumference at least, these spring tongue pieces are engaged in the said holding device and make said brake area centering adjustment and setover in the axial direction with respect to said holding device as a means of being used for.
In a known thread brake (WO 94/12420-PCT/EP 93/03262), the common spring assembly that constitutes said thread brake of spring tongue piece that a plurality of integral body are connected in the frustoconical brake body and extend along the bus of truncated cone body.Spring tongue piece reaches outside the small-diameter end portions zone of brake body truncated cone portion.The free end of spring tongue piece is loosely joined in the recessed ring seat of cup-shaped holding device.Spring tongue piece can be sent to the axial bias load that specially produces on the brake area of the brake collar that is positioned at the brake body inboard from holding device yieldly, and brake collar is pressed on the round and mellow unwinding wheel rim of thread-carrier yarn storage cylinder vertically.With coil form be stored in yarn on the yarn storage cylinder when the unwinding by the brake clearance between brake collar and unwinding wheel rim and rotate around the unwinding wheel rim simultaneously.Because the free end of spring tongue piece loosely is bonded in the holding device, so brake body can be realized the rolling motion with respect to the yarn storage cylinder axis.The maintenance pin of holding device is passed between the spring tongue piece or the groove within several spring tongue pieces drops to prevent brake body.Because spring tongue piece is straight, the spring assembly of the brake body that links into an integrated entity is more stiff in the axial direction, is difficult to the axial bias power of brake collar is carried out meticulous adjusting.In addition, the canting resistance ratios of brake body when operation and in its holding device is higher, stops correctly own centering adjustment.The supporting of straight spring tongue piece and the friction-loaded in holding device thereof hinders the rotation comformability of brake collar on yarn storage cylinder unwinding wheel rim when thread-carrier is operated.This can cause additional stress and/or causing wearing and tearing on brake collar on the yarn.
At a similar thread brake (EP-B1-0668841), become the whole spring tongue piece that is connected in the brake body to extend along the bus of truncated cone portion basically.The narrower spring assembly of brake body that causes of spacing between spring tongue piece is harder in the axial direction.Said accurate adjusting or the variation that firmly brake body necessary radially variable shape property in the brake area zone is had negative effect and can stop axial bias power.
