Abstract
The double torsion twisting mechanism includes a rotatable spindle which rotatably supports a bobbin. A coupling unit connected to the bobbin has its axis offset to the bobbin axis to prevent rotation of the bobbin. A yarn ballooning plate is secured to the spindle and rotates the coupling unit via a flexible membrane connected between the plate and the coupling unit. The flexible membrane is cut-out in the region of a radial yarn guide channel which rotates with the spindle.
Claims8
A double torsion twisting mechanism comprising:
- a hollow spindle rotatably mounted in a stationary support for rotation about a main axis,
- a rotating part secured to said hollow spindle, said rotating part having a radial yarn guide channel,
- a rotating plate secured to said rotating part,
- a bobbin-holder rotatably mounted on said spindle for rotation relative to the spindle about said main axis,
- a unit rotatably mounted on said support for rotation about an offset axis at an angle to said main axis, said unit being rotatably mounted on a housing of said bobbin-holder for rotation about said offset axis,
- a flexible membrane having an outer edge and a central opening defining an inner edge, said membrane being secured by its outer edge to said rotating plate and by its inner edge to said unit, said membrane including at least one radial passageway for said radial yarn guide channel.
