Mechanics of 1x1 rib loop formation on a dial and cylinder machine: Part II-Measurement of cam force

Abstract

The cam force, i.e. the yarn tension, inside the knitting zone for a complete loop forming cycle has been measured on a dial and cylinder machine equipped with 1x1 rib gating to validate the model developed for the purpose and to understand the mechanics of loop formation. A separate cam track has been designed for running the isolated measuring needle and other necessary modifications have been made on the cam jacket for installation of the quartz force link. The cam force signals generated by the quartz force link fitted on the stitch cam are recorded in computer through analog-to-digital convertor. The recorded digital values are then plotted with the help of available software for getting cam force curves which have, in general, four peaks.
