ABSTRACT
This chapter focuses on the lapping motions only and explains the main types of motion movements of the guide bars. In the case where the lapping movement leads to a loop building, the name of the lapping motion is the same as the name of the “stitches”. The lapping movement of the guide bars determines the type of interlacement of the yarns, and in this way most of the properties of warp knitted structures. The lapping motions give the foundation of warp knitting patterning as the pattern consists of several laps in parallel. In crochet knitting machines there are several guide bars, which are performing only such motion and their programming or cams require only the gap number, written once. For the machines with available chain links or electronic drives, any motion is possible, such as placing the yarn around one wale and then connecting to another wale used often in the production of mesh structures, for instance.
