The knitting activity or sew formation to create one training course of loopholes on a crochet equipment outfitted with latch needles contains the following phases:
The weft inlay
Clearing the warp overlap
The warp overlap wrap
Warp knock over as well as underlap
The essence of these phases is composed in the complying with procedures:

1. The inlay: Whilst the needle is taken out into its method during knock-over of the previous warp overlap, the weft inlay tube is reduced. As it passes through in an underlap shog, the weft is laid listed below the degree of the needle and also in addition to the warp thread that expands from its visit the warp overview.

2. Clearing up the warp overlap: The weft tube increases a little on conclusion of its traverse activity to permit the needle to relocate out of its trick to remove its old warp overlap.

3. The warp overlap cover: The warp overview rises between the needles and immediately overlaps from the left, lowering itself once more on the appropriate side of its needle.

Warp knock-over as well as underlap: The needle now retires right into its technique to knockover the old overlap, whilst the warp guide is cammed under its needle to the begin position for its next overlap, hence finishing the shut lap column. NB: The shut lap is utilized for the carbine needle yet the rotating overlap of the open lap pillar stitch used with the standard lock as well as bearded needles provides a more well balanced loop framework.
