摘要 1,170,258. Looms; knitting machines. FRANZ MORAT K.G. 28 Oct., 1966 [29 Oct., 1965], No. 25156/69. Divided out of 1,170,257. Headings D1C and D1E. The pattern control device for a knitting machine or loom of Specification 1,170,257 is modified in that the electromagnetic control head for moving control elements 801 for controlling the actuation of the needles or heddles comprises a pair of opposed centrally converging magnetised tracks 812, 813 which guide lugs 802 of the said control elements towards a central selection zone a controlled by an electromagnet 817 responsive to signals from a pattern which strengthen the field of one track and weaken the field of the other to shift said lugs from one track to the other. Other lugs 803 are then guided onto one or other of two magnetised rails 804, 805 to provide for the actuation or non-actuation of the needles or heddles by driving means. As shown the control elements 801 are in rows in a control box St and aligned with selector rods 716 controlling the hooks 712 of a Jacquard loom adapted to be lifted as required by a griffe frame 701. A control head K for each row (one only being shown) is carried on arms 829 of a plate 827 movable across the rows. When all the control elements 801 have been set the box St is moved bodily as by a pin and slot coupling 763, 765 by the descending griffe frame 701 to move the selector rods 716, and their hooks, of the Jacquard into position for the required pattern. Instead of acting directly on the selector rods the control elements 801 may act through cams or cranks to provide a mechanical advantage.
