Diagram (1.4 d) shows the second swing in the cycle taking the yarn between adjacent needles back to the front of the machine. This is known as a shog movement, specifically the overlap that wraps the yarn around the beard of the needle. 18 Tricot Knitting Diagram (1.4 c) shows the guide bar moving laterally towards the observer. 17 Tricot Knitting In diagram (1.3 a & b) the guide bar swings from the front of the machine (on the right hand side of the diagram) to the back of the machine taking the yarn through the gap between two adjacent needles.
16 Knitting Element Displacements The next movement is a swing from back to front followed by the underlap that may be from 0 to 8 needle spaces depending on the fabric structure being knitted. The first swing from front to back is followed by a lateral shog: the overlap, which wraps the yarn in the needle hook. The front-to-back movements are called swings. 15 Knitting Element Displacements The diagram shows the individual yarn guides set in a solid bar. The front of the machine lies to the right of the diagram. 14 Knitting Element Displacements The diagram summarizes the somewhat confusing displacements made by the guide bar.

Equally the yarn guides are also set rigidly into a horizontal metal bar (the guide bar that runs the full width of the machine). 13 Warp Knitting Technology Warp knitting machines-needles are mounted collectively and rigidly in a horizontal metal bar (the needle bar that runs the full knitting width of the machine). In contrast the compound needle can be closed gently in a controlled manner even at the highest knitting speeds. 12 Knitting Technology Furthermore at the highest speeds (above 2,500 cycles/minute) the issue of latch impact on the hook starts to become a problem with latch needles. 11 Knitting Technology Recently the bearded needle has been dropped and development has focused on the compound needle due to its greater rigidity and ability to withstand higher yarn lapping forces (see Loop formation) than the bearded or latch needle. 7 Needle Technology Until relatively recently warp knitting machines used four types of needle: The bearded needle The latch needle The compound needle The carbine needle Bearded and compound needles were used on tricot machines, the latch needle on raschel and crochet machines and the carbine needle on crochet machines. For comparison, knitting across the width of the fabric is called weft knitting. 2 Warp Knitting Warp knitting is a family of knitting methods in which the yarn zigzags along the length of the fabric, i.e., following adjacent columns ("wales") of knitting, rather than a single row ("course").
