After the filaments leave the quench tank, they must be wiped or blown free of water in preparation for hot-drawing. Wet sections of the yarn will not be heated to the same temperature as the dry sections. The process for drawing monofilaments is very similar to ST. Roll stands and hot ovens, baths, or plates are used for the filaments. The yarns are usually annealed on heated rolls or in an air oven. A two-stage yarn may be used, with a total draw ratio commonly around 6 1. A finish must be applied to the filaments for lubrication and static control. The filaments are wound individually on tubes or flanged bobbins.

The bobbins move on the braiding field on paths that are fixed by the type of machine construction. The threads build up a (curved) area by means of the take-up. Standing ends are inside this area, and they fill in the braid so that it looks voluminous. The standing ends themselves do not penetrate the inside but surround the standing ends like a wall. Only two coordinates are needed to determine the thread deposit in the braid. The geometry appears three-dimensional like in overbraidings (circular braids), but the thread deposit is just two-dimensional. 

Unlike the double lock stitch, the looper thread for the double-chain stitch (Fig. 10.6) is fed from a supply reel on the reel stand over guiding and thread-tightening elements to the thread-guiding gripper. The different phases of the interlacing of needle thread and bobbin thread by a double-chain stitch are as follows ...
