Loom with yarn quality sensor

摘要

The loom has a non-contact yarn quality sensor (12) in the passage of the weft yarn at the transfer zone (8) between the weft guide (9) and the shed (1). The sensor registers the yarn diameter or cross section and detects the presence of any lint. The sensor forms a light barrier with a measurement zone (14) at a frame (13) at right angles to the weft movement line (Y) and an opening (15) across the weft.
