Working principle of needle bar of 36-needle wool catcher

The needle roller mainly winds wool on the inverted triangular spacer through the high-speed rotating head, and the width of the neck of the spacer determines the length of wool.

The needle roller mainly winds wool on the inverted triangular spacer through the high-speed rotating head, and the width of the neck of the spacer determines the length of wool. The yarn feeding roller sends out two core yarns, one of which constitutes the surface core yarn and the other constitutes the bottom core yarn of the yarn. The pile yarn on the spacer is pushed to the blade by the guide wheel, and the blade moves in the middle of the spacer to cut the pile yarn into two sections, which are sandwiched between the face core yarn and the bottom core yarn on both sides. Then, due to the rotation of the 1 ring spindle, the flaky fluff between the two core yarns is scattered around into yarns. This is the process of yarn formation and the working process of spinning machine.

Needle roller, also known as needle cylinder. A metal cylinder with steel needles planted on its surface. It is installed in the drafting area for controlling and carding fibers.
