Sliver fineness control process - has structured control times according to sliver speed between control and monitoring points

摘要

The quality of sliver, for use in a spinning machine, is controlled by continuous control of the drawing action to determine the fineness of the matl., by a value of DELTAd/t (where DELTAd is the magnitude of the control action, and t is the control time) by modifying the throughput speed of the sliver through the drawing station automatically or at least approx. proportionally. The system allows the fineness of the sliver to be controlled at various throughput speeds to give an optimum effect.
