portion 13 meshing with the clockwise rotating peripheral gear 10 is driven at a substantial rotational speed with respect to the plate 6 also counter clockwise when viewed from the top of fig1 accordingly the looping member 11 rotates through the sequence shown in fig4 through 9 including in fig4 the curved lateral portion 14 carries a loop of a first yarn 34 a 34 while the hook 15 approaches the adjacent yarn 34 b 34 in fig5 continued rotation of the looping member 11 has drawn a portion of the yarn b and is allowing the loop formed in yarn a to slip toward the end of the lateral portion in fig6 the drawn portion of yarn b has been pulled through the loop of yarn a which is then free of the lateral portion but still engaged by the drawn portion of the yarn b in fig7 the drawn portion of yarn b has passed from the hook 15 and is passing downward along the curve of the lateral portion 14 fig7 a shows the drawn portion of yarn b as it is about to be twisted into a loop with the hook 15 intermediate to the positions seen in fig7 and 8 in fig8 the drawn portion of yarn b has now twisted into a loop while the hook 15 is approaching the next yarn c as is seen in fig4 7 8 and 9 the drawn portion of the yarn b remains of the lateral portion 14 of the looping member 11 in fig9 the member 11 has rotated close to the position shown in fig4 so that the sequence will be then repeated by drawing a portion of the yarn c through the loop in yarn b.
