Title: Double twisting device has package support platform - with profiled upper surface to create turbulent air flow over yarn
IPC: D01H7/86
Filed: 1973-03-16
Abstract: A double twisting device comprises a hollow rotating spindle carrying a cup which rotates with it, and a support platform freely rotatable on the spindle above the cup. A yarn package is located freely around the spindle and rests on the support platform and a protective pot, supported pref. by stems on the platform surrounds the package. The support platform is prevented from rotating by magnets which are embedded within it and which co-operate with stationary magnets whereby a yarn is fed from the package through the rotating spindle, it is twisted. The upper surface of the platform on which the package rests is undulating and is defined by a surface of revolution generated by rotating a straight line about one of its ends through 360 degrees around the rotational axis of the spindle and by causing the other end of the line to follow a sinuous path. An air flow generated by rotation of the cup passes over the undulating upper surface of the support platform and is caused to become turbulent, and this turbulent air flow passes over the yarn to ensure removal of waste fibres on the surface of the yarn.
