the course shown in fig2 34 the rear needle bed 7 is now moved by racking 1 5 pitches leftward from the position shown in fig2 34 or to a position 0 5 pitch leftward distant from the reference position as shown in fig2 35 and at the course shown in fig2 36 the two loops on the rear knitting needles a and b are transferred back onto the front knitting needles a and b respectively at the course shown in fig2 37 the rear needle bed 7 is further moved one pitch leftward from the position shown in fig2 36 or to a position 1 5 pitch distant from the reference position then the loop on the rear knitting needle c is transferred onto the front knitting needle b as shown in fig2 38 accordingly the front knitting needle a carries two loops while the knitting needle b holds three loops at the course shown in fig2 39 a loop is formed between the two knitting needles a and b as the result the number of loops on the four front knitting needles a b c and d shown in fig2 27 is reduced to a half and a series of arch patterns of the stitches is now produced along the edge of the neck portion 2 of the pullover 1 the last loop between the two knitting needles a and b is then fastened as shown in fig3 1 to 3 5 more specifically the loop on the front knitting needle b is first transferred onto the rear knitting needle b as shown in fig3 1 then the rear needle bed 7 is moved by.
