Abstract
A cap spinning machine includes a spindle which supports a spool and a cap covering the spindle and the spool. The cap is supported in a freely rotatable manner and is brought into a rotating motion by the spindle via a thread which is guided around the outer surface of the cap to the spool. Consequently, the rotational speed of the cap is automatically controlled depending on the lagging of the cap behind the rotation of the spindle. By means of a driving and/or braking device, the driving force of the cap transmitted by the spindle via the thread is additionally controllable so that the tensile force of the thread and thus the closeness of the formed winding is influenced as well.
Claims18
A cap spinning machine, comprising:
- a rotating spindle defining an axis;
- a spool sleeve connected to said spindle along a portion thereof and being provided to carry a thread winding forming a spool;
- a cap extending over said spool and said sleeve and being rotatable about an axis of rotation;
- means for rotatably supporting said cap;
- guiding means arranged in the axis of rotation of said cap for leading the thread in helical manner around the outer surface of said cap, said cap being brought into the rotational motion by said spindle by means of the thread so that the rotational speed of said cap is entrained in rotation by the thread;
- and
- means for axially displacing said cap and said spool relatively to build said spool on said sleeve.
