摘要：538,839. Knitting. BOOTON, Ltd., W. E., and BOOTON, W. E. Feb. 16, 1940, No.2945. [Class 74 (ii)] A two - feed circular machine knits a stocking &c. blank havingalternate courses of the leg formed of different threads and the toe pocket linkage lineformed in the foot bottom. The heel pocket h is knitted by reciprocation upon one groupof needles at one feed, and the toe pocket t is formed by reciprocation by an opposedgroup of needles at the other feed. The stocking blank is knitted from the toe upwards,the toe being knitted upon the instep needles LB at one feed 2, and after the heel hasbeen knitted upon short butted needles SB at the other feed 1, the leg is knitted at bothfeeders by the needles LB, SB and intermediate needles MB. During rotary knitting of thelower part of the leg, needles SBx with still shorter butts are retained out of operation,and the yarns are floated between the ends of the two groups SB. For fashioning, theneedles SBx are introduced at each end of the already operating needles, and to permitneedles to be picked successively from the trailing end of a group of needles, pickermechanism as described in Specification 537,965 is provided. This picker mechanismoperates upon jacks arranged beneath the needles, and similar picker mechanism isemployed to introduce needles successively for forming shaped splicing areas. Theseareas are knitted by the short butted heeling needles SB and by the intermediate

needles MB, and a picker mechanism may be provided at each feeding position tointroduce the splicing needles. As described, a picker mechanism for introducing thefashioning needles to the operative path is provided only at the feeder 2. Mock

fashioning marks i, k may be formed by tucking on needles equidistant from the needlesintroduced by the picker mechanism. Upon completion of the leg, when all of the needlesSBx have been introduced, at least one reinforced course l is produced, followed by apicot edge and a welt n. The blank having been completed, the floating threads are cutaway, and the toe pouch is linked to the foot bottom and the edges of the foot and legare seamed along a line which extends upward from the toe linking line to the course l.The seam so formed may be continued as a mock seam through the tubular part of thestocking.
