Abstract
In the case of ring spinning with condensing devices there is a risk that the yarns of the individual cops have a varying degree of hairiness. This can result in faults in the end product, for example a woven fabric. In order to avoid such faults, the ring spinning machine is connected to a monitoring station, in which the yarns are automatically monitored for hairiness; the cops, based on the monitoring results, are then automatically sorted.
Claims51
A process for monitoring quality of a ring spun yarn from a ring spinning machine with a condensing device at each of a plurality of spinning stations, comprising:
- winding spun yarn from respective spinning stations onto cops,
- transporting the cops with spun yarn wound thereon away from the spinning machine, and
- automatically monitoring hairiness of the yarn on said cops during said transporting while rotating the cops during said monitoring.
Apparatus for monitoring quality of a ring spun yarn from a ring spinning machine with a condensing device at each of plurality of spinning stations, comprising:
- winding means for winding spun yarn from respective spinning stations onto cops,
- transporting means for transporting the cops with spun yarn wound thereon away from the spinning machine, and
- monitoring means for automatically monitoring hairiness of the yarn on said cops during said transporting while rotating the cops during said monitoring.
