Abstract: 1,218,307. Knitting-machines. SOLIS SRL. 5 Aug., 1969 [14 Aug., 1968], No. 39040/69. Heading D1C. A shearing device for longitudinally slitting fabric as it is knitted on a circular machine is mounted on a support 10 below the dial and can be projected to an operative position. The fabric may be cut by blades 22, 14A or seared by a heated wire. Blade 14A comprises one end of a bell crank pivoted on the support and moved to an inoperative position against the action of spring 16 by a rod 28. The bifurcated end 26 of the rod engages the end of the other blade. The rod can be reciprocated by a pivoted lever 32 connected by link 40A to slide 38 movable on post 36. When the device is to be operative spring 41 urges the slide upwards to lower the rod which permits spring 16 to project the blades. The link 40A is reciprocated relative to slide 38 by engagement of lug 40B with cam track 46 and thus oscillates rod 28 and the movable blade. The blades may be replaced by a heated wire similarly projected, and energised by engagement of contacts (86, 84A fig. 3 not shown) when the rod is lowered. The cut edges are fused by the wire but immediate contact of the two edges is prevented by a projection below the wire.
