Figs. I to IV-C. These show a repeat of courses 1 to 4-B, illustrating the distortion of the selvedge loops due to the fact that some of the loose loops of the main yarn are drawn up through subsequent loops of the main or splicing yarns. The last Fig. (IV-C) shows the ultimate result obtained in the fabric.
METHOD OF WIDENING (BY POINTS) ON FULLY-FASHIONED MACHINES
Fig. 35 shows a diagrammatic drawing of a flat, fully-fashioned stocking blank, showing the manufacture of a stocking with round heel, made on a single machine, also view of one side of this heel section as shown in Fig. 36.The stocking is formed as a flat stocking blank, commencing with a top portion known as the welt (A) followed by an afterwelt or shadow welt (B). The leg fabric is now reduced in width by flare narrowings (C), the number of these used depending upon the gauge of machine used in the manufacture. Knitting is continued straight (D) until the calf portion is reached. The calf fashionings (E) are carried down to (F) to provide between (F) and (G) an ankle portion which, by regulation of the number of narrowing fashionings, is made sufficiently narrow to fit the ankle. The narrower the ankle, the greater number of widening operations necessary to obtain the correct width of area (L).
The formation of the heel section now begins. This consists of a widening of the stocking blank up to 25 widening steps, two loops being added at each step. The first widening (W1) is carried out between (H) and (I), near the upper end of the usual high splice (G) and may consist of 6 widening steps at 5-course intervals, each adding 2 edge loops. The portion between (I) and (J) requires a rapid increase, therefore the fashioning area (W2) may consist of 9 widening steps, each of which gives 2 edge loops at intervals of 3 courses, so as to produce a nice round heel.
It is advisable to add further widenings at less frequent intervals,
