Abstract
The cap of a cap spinning device comprises a thread introduction attachment in the top or upper region of the cap. In this thread introduction attachment there is arranged an inlet passage which is upwardly directed at an inclination and provided for the thread coming from the drafting arrangement via a thread eye, so that a balloon is formed between the thread eye and the top or upper side of the cap.
Claims14
A cap spinning device, comprising:
- a drivable spindle having an axis of rotation;
- a cap arranged substantially coaxially with respect to said drivable spindle and capable of being rotated about an axis extending substantially coaxially with respect to said axis of rotation of said drivable spindle;
- said cap being provided with a balloon forming thread introduction attachment;
- said balloon forming thread introduction attachment guiding a thread into said axis of rotation of said drivable spindle;
- said balloon forming thread introduction attachment containing a body provided with a substantially central bore having two ends;
- one end of said two ends of said substantially central bore opening into the interior of the cap;
- and
- said body of said balloon forming thread introduction attachment containing at least one inlet passage extending at an inclination from an other end of said two ends of said substantially central bore through said body of said balloon forming thread introduction attachment.
