Abstract
A ring-spinning machine has spindles with head pieces, e.g. with fingers about which the yarn can be wound to reduce the ballooning of the yarn around the respective spindles. The thread-guide eyes above the headpieces can be depressed against a spring force from normal positions to enable the yarn to wind around the fingers and the spring force restores the eyes to their normal positions, thereby avoiding changes in the distances between the normal positions and the headpieces which may alter the spinning properties and yarn quality.
Claims14
A ring spinning machine comprising:
- a respective upright spindle at each of a multiplicity of ring spinning stations;
- a ring surrounding said spindle and forming a guide for a traveler;
- a headpiece on said spindle for limiting development of a yarn balloon between said headpiece and said traveler as said yarn is deposited on a core sleeve on said spindle;
- a thread-guide eye above said headpiece and guiding said yarn onto said headpiece;
- a support on the machine carrying said thread-guide eye;
- a holder for said thread-guide eye swingably mounted on said support between a normal position of said thread-guide eye aligned with said headpiece and an upwardly swung position of said thread-guide eye, said thread-guide eye being deflectable toward said headpiece;
- and
- spring means acting upon said thread-guide eye for biasing said thread-guide eye into said normal position upon deflection of said thread-guide eye from said normal position toward said headpiece.
