Abstract
An automatic fabric-density adjusting device is provided and includes a detecting device for detecting the rotary movement of a knitting machine, a driving mechanism for driving a yarn positive feeding device in response to the signal detected by said detecting device, a controller for controlling the driving mechanism to cause said yarn feeding device to feed a requisite yarn volume for the desired fabric, a fabric tension sensor for detecting variations in the tension of the knit fabric and signaling the controller to vary the take-up of the fabric accordingly. An automatic yarn-feeding control device is also provided and comprises several knitting needles,, a yarn-feeding device, which supplies knitting yarn to the knitting needles by a yam carrier, a cylinder, which houses the knitting needles in its needle groove, a cam holder, which faces the cylinder and is equipped with a control cam for controlling the knitting needles, and a cam ring, which supports the cam holder, and a yarn tension sensor for determining variations in tension and for signaling the controller to vary the knit stitch volume.
