Title: Yarn paraffin coating - computes expected life of paraffin body for control of exchange according to parameters of moving yarn in contact with body
Inventor: KNORS HERBERT
IPC: D02J3/18
Filed: 1992-08-08
Abstract: To monitor the application of paraffin to a moving yarn, as it is passed in contact over a paraffin body, the length of body (9) life is computed to the point where it has a min. size, using the weight (A) of the body (9), the friction take-off application rate (B), the yarn thickness (C) and the bobbin speed (D). Also claimed is an appts. with a control (7) system for the textile machine to compute the remaining life of the paraffin body (9). A computer (27), for the textile machine or the winder, automatically takes a number of parameters to compute the remaining life of the paraffin body (9) until it is reduced to a min. size, for a control (7) which generates a signal at the end of the usage time calculated. At the end of the time, the paraffin body (9) is exchanged and the control (7) is disengaged. The winding station is switched off if the body (9) exchange is not effected and the control remains disengaged, or an affected section of the spinning or winding assembly is switched off. If there is doubt on the rate of paraffin removal (B) from the body (9), the value is estimated with a safety reserve, for later correction if required. USE/ADVANTAGE - The method is for the application of paraffin to a moving yarn, as it is wound, by contact between the yarn and a paraffin body. The system monitors the life of the paraffin body, to ensure that it does not expire without warning, in a simple and cheap assembly.
