Estimating the term…
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 53, 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.
In a circular knitting machine including a rotatable needle cylinder having needle grooves therein, a knitting needle slidably mounted in each needle groove in said cylinder, a cam holder facing said cylinder, needle operating cams carried by said cam holder and having cam tracks engageable by butts on said needles for moving said needles between their various positions, and a positive yam feeding device for feeding yarn to said knitting needles, in combination therewith an automatic yarn feeding control system including
An automatic fabric density adjusting system for a knitting machine comprising
