Abstract
A device for contactless measurement of one or more parameters of a linear textile formation (e.g., yarn) includes a yarn sensor with at least two mutually independent detection zones for one or a combination of the parameters of yarn presence, yarn movement, or yarn quality. The individual detections zones are arranged in defined positions relative to at least two different yarn paths of the yarn at a workstation depending on changed states of the yarn at the workstation so that at least one of the parameters is measured in each of the detections zones.
Claims18
A device for contactless measurement of one or more parameters of a linear textile formation, comprising:
- a yarn sensor, the yarn sensor further comprising at least two mutually independent and spaced-apart detection zones for one or a combination of the parameters of yarn presence, yarn movement, or yarn quality;
- and
- wherein the detection zones are arranged in defined spaced-apart positions relative to at least two different yarn paths of the yarn at a workstation that depend on changed states of the yarn at the workstation so that for each of the different yarn paths at least one of the parameters is measurable in at least one of the detection zones.
