Abstract
A break in twice as many yarns is made detectable merely by slightly modifying the tension switch assembly of a knitting machine. A yarn conductor 20 is rotatably attached to the forward end of an arm 16 of the assembly and provided with a pair of yarn supports 26, 27 on opposite sides of a rotational pin 19. Upon a break occurring in the yarn 2 retained on one of the yarns supports 26, 27, torques exerted by the yarns 2, 2 on the respective supports 26, 27 are brought out of balance to rotate the yarn conductor 20 and release the remaining other yarn 2 from the support 27.
Claims10
A tension switch assembly for use in a knitting machine said tension switch assembly Comprising:
- an arm;
- a main body and a sensor for detecting a pivotal movement of said arm;
- said arm including a forward end for guiding a yarn, and a base end pivotably attached to the main body to tension the yarn, the sensor being operable to detect the pivotal movement of said arm due to a break in the yarn to stop an operation of the knitting machine, the tension switch assembly further comprising a yarn conductor having a rotation supporting point thereof and a pair of yarn supports arranged respectively on opposite sides of the rotation supporting point, said yarn conductor being coupled to a forward end portion of said arm, said pair of yarn supports being rotatably disposed about said rotation support point.
