Description

Technical Field

[0001] The present application relates to the technical field of a device for determining the number of turns of a yarn feeder, and in particular to a device for determining the number of turns of a yarn feeder. Background Art

[0002] In the process of producing non-woven fabrics by circular knitting machines, the weight of the produced cloth is different due to the different thread feeding amounts of the yarn feeder. At present, whether the thread feeding of the yarn feeder is normal can only be judged according to the final weight of the cloth. If there is no problem with the thread feeding, the final cloth weight will not deviate much from the requirement. If there is a problem with the thread feeding, the cloth weight will be much higher or much lower than the requirement.
