抄録

A demand has arisen for a higher spindle-speed and large packages as means for better efficiency in high-speed twisting of tire cord. In view of this demand, we have made experiments with large packages and at a high twisting-speed…and investigated what bearing this will have on the various processes of twisting.<BR>A ring 140mm in diameter was used for the first stage in twisting. A twisting frame 203mm long was used in the lifting stretch of twisting.<BR>Another ring, 177mm in diameter, was used for the final twisting stage. Another twisting frame, 245mm long, was used in the lifting stretch.<BR>The experiments have shown that:<BR>(1) Spindle revolutions can be increased to 7000rpm in the first twisting; to 5500 in the final twisting. About twice as many packages are obtainable as under ordinary conditions: a ring 90mm in diameter and a lifting stretch 203mm for the first twisting; a ring 140mm in radius and a lifting stretch 203mm for the final twisting.<BR>(2) A nylon traveller containing a special substance to increase the traveller's anti-wear properties can be used, without trouble, at a high traveller-speed. There are fewer variations in twisting tension, so that there is no decrease in the strength or elongation properties of the yarn.<BR>(3) Power consumption increases, however. This is a point requiring attention in putting the operation under review into practice.
