PCT No. PCT/GB85/00554 Sec. 371 Date Aug. 1, 1986 Sec. 102(e) Date Aug. 1, 1986 PCT Filed Dec. 6, 1985 PCT Pub. No. WO86/03524 PCT Pub. Date Jun. 19, 1986.A flat-bed knitting machine has yarn restraining devices (10) disposed adjacent opposite ends of the stroke of its cam box (4) for controlling the supply of yarn (Y) to the needles so that no loops are formed at the edges of the knitted fabric produced on the machine and no tension is applied to the yarn by the devices while the rows of stitches are being knit. Each device (10) comprises a spring arm (12) for engaging with a cooperating flat surface (17) on the top of the cam box (4) during movement thereof over a predetermined end portion of the stroke and for trapping the yarn (Y) between the arm (12) and the surface (17). The arm (12) is adapted to retain the yarn so trapped as the cam box (4) commences a reverse stroke and until the yarn is re-engaged by the cam box with the adjacent working needle, whereupon a pull is exerted on the yarn to release it as the cam box commences a fresh row of stitches.
