Abstract

1320502 Knitting machines TRIPLITE Ltdl8 June 1970 [20 June 1969] 31214/69 Heading D1C A positive yarn feed has a band, tape or the like 15 to apply feed to the yarns which is driven by a variable diameter wheel 20 adjusted by a stepping motor 29 activated as and when required. As shown in a circular knitting machine, positive yarn feeding rollers 13, 14 are driven from the tape or band 15. Pulley 20, see Specification 1320501, comprises blocks 21 engaged by belt 19 and slidable under the control of a cam disc 24 on pairs of parallel radial spokes 22 carried on a holder 23 secured to shaft 12. Cam disc 24 is rotated on shaft 12 by the engagement of its toothed edge with pinion 26 driven by an A.C./D.C. stepping motor 29 carried on a disc 27 on shaft 12 to vary the diameter of pulley 20. Slots 35 in a disc 34 rotatable with shaft 12 pass through a photo-electric scanning head 36 producing impulses to energize the stepping motor for forward or reverse movement. A shaft 41 on top of motor 29 aligned with shaft 12 through a pulley and belt drive, drives a pulley 44 with rods 48 carrying a disc 49 with a single slot 50 which co-operates with a further scanning head 51 similar to head 36. When, during knitting, a change in the yarn feed is required, head 36 will be switched on, e.g. by a patterning chain, for the required direction of movement of motor 29, the amount of adjustment being controlled by covering slots 35. For finer adjustment, disc 50 is used, adjustment being by substituting different sizes of pulley 42. Resetting of pulley 20 is achieved by running motor 29 continuously in the appropriate direction to restore it to its initial state. Thus the necessary progressive variation in loop size to produce shaping of a stocking or leg blank for a panti-hose can be produced.
