The machine use the computer needle selector to select the needle on the needle cylinder, can knitting the jacquard fabric with unlimited pattern range. The computer needle selector can be made into loop, miss and float three power position selector. The process pattern of any complex organization can be changed into a special control command through a computerized pattern preparation system. These instructions control a computerized needle selector on a machine to weave single jersery jacquard fabric.

Precision encoder can accurately calculate the position of the needle and correct zero, the encoder can also automatically correct the error caused by inertia when starting and stopping. Additional control system can check the encoder, determine whether the signal of the encoder is appropriate, so as to ensure the stability of the entire system to ensure the accuracy of needle selection.
