Abstract
A twisting device having a pair of fiber cakes that are simultaneously hung on a transversely disposed creel, respectively unwind two fiber strands downwardly during the rotation process of the creel. Each of the two fiber strands passes through a strand-cut sensor and then enter a balloon control ring. Through the guide of an oil ring, each of the fiber strands is twisted and then wound around a bobbin driven by a spindle motor. The pair of balloon control rings and the pair of oil rings are simultaneously driven by a ring rail to move upward and downward on the bobbin.
Claims4
A twisting device having enhanced productivity, comprising:
- a creel;
- at least two fiber cakes coaxially and rotatably arranged on said creel, each of said fiber cakes having a respective fiber strand unwindable therefrom to extend downwardly;
- at least a pair of strand-cut sensors disposed below said creel, each of said fiber strands passing through a respective one of said pair of strand cut sensors;
- a ring rail disposed at a lower portion of said twisting device and being reciprocally driven upwardly and downwardly;
- at least two balloon control rings respectively disposed beneath said strand-cut sensors and coupled to said ring rail for displacement therewith;
- at least a pair of oil rings respectively disposed beneath said balloon control and coupled to said ring rail for displacement therewith, each said oil ring being joined with the other oil ring and each having an oil-supplying device;
- and,
- at least two bobbins respectively disposed below said oil rings, each of said fiber strands passing through a respective one of said balloon control rings and a corresponding one of said oil rings to a respective one of said bobbins, each of said bobbins being rotatably driven to twist each respective one of said fiber strands and respectively wind each said twisted fiber strand on a corresponding one of said bobbins.

- at least two strand-cut sensors disposed below said creel, each of said fiber strands passing through a respective one of said strand-cut sensors;
- at least two balloon control rings and at least two oil rings respectively provided below said strand-cut sensors, said oil rings being disposed below said balloon control rings, said balloon control rings and said oil rings being connected to and driven by a ring rail to make upward and downward reciprocal motions;
- and
- at least two bobbins provided below said oil rings and being rotatably driven so that said fiber strands are each respectively twisted and then each wound on a corresponding one of said bobbins, said strand-cut sensors being mounted to a supporter, said supporter including:
- (a) a supporter plate, one of said strand-cut sensors being mounted to said supporter plate;
- (b) a first member having a first end thereof pivotally coupled to said supporter plate to be foldable beneath said supporter plate;
- and,
- (c) a second member pivotally coupled to a second end of said first member to be foldable beneath said first member, the other of said strand-cut sensors being mounted to said second member.
