Abstract
A control system which allows a plurality of shapes to be knitted by a simple change of profile cam (80). The profile cam (80) controls in a desired variable manner the feed rate of elastic or ground yarns to control the shape of a garment. The shape can also be controlled by further profile cams (200, 202, 204) to control both elastic and ground yarns and in a dial and cylinder circular knitting machine to alter the dial height while the machine is in motion, thereby further controlling the width of a garment.
Claims10
A control system for a circular knitting machine the control system including a main drive shaft, and means for varying the rate at which yarn is supplied to the machine in a controlled manner over a period of time such that the shape of the workpiece is controlled by the rate of yarn feed, said means for varying the rate at which yarn is supplied to the machine including a rotatable profile cam, and a variable speed pulley fixed on said main drive shaft for rotation therewith, and wherein said rotatable profile cam acts in a direct linear manner upon said variable speed pulley to control the yarn feed supply rate.
