Abstract
A yarn tension control device of knitting machines is revealed. A plurality of yarn tension control devices is disposed on a knitting machine for control of warp yarns while weaving the warp yarns to produce fabrics. The warp yarns can be metal yarns. The metal yarns on a yarn disc are passed through a guide holder, bars for drop wires, and drop wires and then entered steel healds and reeds. Thus a constant yarn tension over the warp yarns is ensured by the yarn tension control devices during a weaving process of weft yarns. The tension of the metal yarns is the same with the tension of textile yarns. Thereby a stable yarn tension over the warp yarns gives uniform fabric appearance.
Claims11
A yarn tension control device disposed on a knitting machine comprising:
- a main support installed over the knitting machine and being inserted with a main shaft;
- a yarn disc wound with yarns and disposed on the main shaft;
- a rotary disc arranged at the main shaft;
- a rotatable clamping roller disposed on the main support and used for pressing against the yarns of the yarn disc;
- and
- a friction damper arranged at one side of the rotary disc and used to control and adjust rotational speed of the rotary disc;
- wherein a plurality of the yarn tension control devices is disposed on the knitting machine while in use;
- the yarn disc and the rotary disc are disposed on the main shaft and are rotated at the same speed along with the yarns being drawn by an external force.
