    Operation of LZE-V LabPack IPI Imperfections IPI 7.19.5 The classical yarn clearing in the winding process is designed for the record- ing of thick/thin places in the yarn which are defined according to the respec- tive fault classes. In yarn fault classification, “rare” and “frequent” yarn faults are distinguished. The general rule is that the shorter the fault length or the smaller the diameter variation, the more frequent the events.
