<p>A break in one of a pair of yarns (2, 2) is made detectable by 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). <IMAGE></p> |
