Abstract
A servicing arrangement selectively displaceable along an open-end spinning machine which includes a number of individual spinning stations. At least one measuring head is arranged on the displaceable servicing means so as to selectively monitor the quality of the running thread or yarn at the individual spinning stations. A control apparatus is operatively associated with the measuring head and receives signals therefrom, whereby the control apparatus regulates elements for arresting a spinning operation at a spinning station and/or marks individual spinning stations and/or blocks a piecing operation at the spinning stations when the quality of the running thread or yarn at such stations is below a predetermined quality.
Claims29
Servicing apparatus arrangement for an open-end spinning machine comprising:
- a mobile servicing carriage,
- means for moving said servicing carriage along a predetermined guide path to respective servicing positions adjacent respective spinning stations of the spinning machine,
- thread quality monitoring means carried by said servicing carriage, said monitoring means including at least one thread quality measuring head means and adjusting means for adjusting the position of said measuring head means to selectively detect the quality of the thread being produced at a respective spinning station,
- and control signal means for providing a control signal to a spinning machine control means in response to detection of quality defects in thread running by said measuring head means.
A servicing arrangement displaceable along an open-end spinning machine having a plurality of individual spinning stations, each of which produces a running thread, the arrangement comprising:
- means for monitoring the thread at each spinning station including at least one measuring head means associated with the running thread for selectively detecting the quality of the running thread and providing a control signal to a spinning machine control means, and
- wherein said measuring head means includes a measuring head and a pivotally mounted lever means for displacing said measuring head from a rest position to a detecting position.
A servicing arrangement displaceable along an open-end spinning machine having a plurality of individual spinning stations, each of which produces a running thread, the arrangement comprising:
- means for monitoring the thread at each spinning station including at least one measuring head means associated with the running thread for selectively detecting the quality of the running thread and providing a control signal to a spinning machine control means, and
- wherein a plurality of measuring head means are provided and arranged so as to be selectively aligned with an equal number of adjacent spinning stations, and a common setting means for displacing said measuring head means from a rest position to a thread detecting position in response to a signal from the control means is provided.
