of forming a new loop by supplying the yarn 3 to the front knitting needle h and the action of transferring the old loop held on the front knitting needle h to the rear knitting needle h through the newly formed loop occur coincidentally in the above method that is 34 split knit 34 is done in the above method the two actions may occur step by step in fig4 5 the rear needle bed 6 moves 1 pitch leftward from the position shown in fig4 4 and loops held on the rear knitting needles d to h are transferred to the front knitting needles c to g in fig4 6 a yarn 4 tucked on the front knitting needle i is supplied to the front knitting needles c to h and loops are formed on them thus the loops held on the front knitting needles d to h in fig4 3 are now held on the front knitting needles c to h by this way a loop for forming the left side edge 2a of the neck portion 2 is added that is the action of 34 widening stitches 34 is done a knitting structure formed in the knitting courses fig4 3 to 4 6 appears to be as indicated with an arrow in fig5 at the courses shown in fig4 7 to 4 10 almost the same action as the courses shown in fig4 3 to 4 6 is done to increase the number of loops for forming the right side edge 2b of the neck portion 2 more specifically.
