Abstract: 1,229,047. Knitting. M. B. NEBEL and E. M. NEBEL. 25 April, 1968 [25 April, 1967], No. 19732/68. Addition to 1,158,042. Headings D1C and D1K. In an improvement in the method claimed in Specification 1,158,042 in which loops are held, in rearwardly opening sinker slots S below the throats, to be incorporated in a subsequent course held loops F are held in certain sinkers only and, yarn of the held course D 2  between the held loop F is held in the sinker throats P until at least after the next course. The method relates to the knitting of a turned welt. In one method yarn of the first course D 1  is laid in front of the needles N 1x  N y  and behind needles N 2 . On the second course yarn is taken by needles N 1x  and laid behind needles N 1v  on the throats of sinkers P 2 . The same yarn is laid on top of the hooks of sinkers P 1  on either side of needles N 2 , which draw tuck loops. Before the third course D 3  is knitted the needles are lowered from tuck level by an additional cam (C x  Fig. 3 not shown) to the level of slat S. Simultaneously the sinkers P 1 , having a butt nearer the far end of the sinkers than sinkers P 2 , are pushed into the needle circle. The loops are caught in the slot for retention, by withdrawing the sinkers. The outer edge of the sinker ring is cut away or bevelled to permit passage of the loops behind the needles. On the third course D 3  yarn is taken by needles N 1x  N 1y , and laid behind needles N 2  or drawn into a tuck loop. The fourth course is taken by all needles; needles N 2  forming a tuck loop. In an alternative method the first course is laid alternately in front of and behind alternate pairs of needles, N 1  and N 2  respectively. On the second course needles N 1  draw loops and needles N 2  draw connecting loops which are held in the slots of three sinkers. On the third course one needle of each pair knits yarn D 3 , one of the pair N 1  tucks yarn D 2 . In a further alternative yarn of the first course is taken by alternate needles only, being laid behind interveening needles. Connecting loops are formed on the second course by alternate interveening needles only, and may be held by one sinker only. In a further modification (Figure 11 not shown) the yarn is knit by alternate needles (N 1 , N 3 ) and laid behind interveening needles (N 3 , N 4 ). On the second course alternate interveening needles (N 2 ) form tuck loops on the sinker hooks and are pulled into the sinker slots, the remaining needles (N 4 ) forming floats (4) or tucks (F a ). On the next course all needles take yarn and tuck loops (F 2 ) are formed by needles N 4 . These tuck loops together with loops F a  if formed in course D 2  are moved to the sinker slots to make a turned welt connected by alternate loops. In the method of Figure 12 (not shown) yarn is knit by alternate needles and laid behind interveening needles. In the second course needles not previously taking yarn from tuck loops (F 1 , F 2 ) on or behind the sinkers and alternate ones (F 1 ) are moved into the slots. After the third course, in which needles having tuck loops are back floated, the remaining loops are moved into the slots.
