Abstract
In an open-end friction spinning machine having a plurality of spinning units, each containing two friction rollers that are arranged next to one another, form a wedge-shaped gap and are drivable in the same rotational direction by means of a belt drive, a common belt drive is employed. Each spinning unit is equipped with an automatic disengaging device for disengaging the belt drive of that unit. This disengaging device contains at least one spring-loaded tension pulley holding the belt drive in the driving position. The operational position of the tension pulley is secured by means of a locking device, and the tension pulley is automatically disengaged from the drive belt when the locking device is opened.
Claims20
An open end friction spinning apparatus comprising:
- a plurality of spinning units, each said unit comprising two friction rollers arranged adjacent to one another to form a wedge-shaped yarn-forming gap therebetween;
- common drive means engaging a plurality of said spinning units, wherein said common drive means comprises belt drive means;
- at least one rotatable spring loaded tension pulley means associated with each spinning unit for engaging said belt drive means, said pulley means causing said drive belt means to engage said rollers, and
- automatic disengaging means for disengaging each said tension pulley means from said belt drive means thereby disengaging said belt means from said roller means.
