Description

Knitting machine with positioning mechanism

The invention is applied to the technical field of knitting machines, especially a knitting machine with a positioning mechanism capable of positioning and stably conveying fabrics.

Generally, because the fabric is made of soft material, it is not easy to effectively locate after the first processing operation of the warp knitting machine. Therefore, after the first crochet is completed, it is not easy to carry out the second or more processing on the semi-finished fabric. However, due to the ever-changing demand for fabrics, it may be necessary to process the fabric more than two times to meet the needs. For example, in order to increase the safety of the drawstrings in the blinds, some countries have amended the law to hide the drawstrings on the ladder belt. To avoid the drawstring being exposed, it is easy to cause young children to wrap around the neck by mistake and cause danger.

However, because the current existing warp knitting machine cannot cooperate with the new ladder belt design, it provides secondary processing, so that the existing ladder belt is subjected to secondary processing on both sides to form the design of the hidden drawstring, thus causing the existing warp knitting machine If the machine cannot be used, it may be necessary to redesign the additional warp knitting machine, resulting in the idleness and waste of the existing machine.
