Yarn twisting machine comprising a yarn tension applying device |
(57) In a yarn twisting machine that generates one twisted yarn from two raw yarns, defects
such as hanging down of the yarn are generated due to a lack of tension.
In a yarn twisting machine 1 in which a supply yarn package 10 is provided at an upper
side of a machine frame 2 and a gate tensor 49 is provided for applying tension to
second yarn Y2 unwound from the supply yarn package 10 at an upstream side of the
yarn of a yarn twisting device 8 located at a lower side of the machine frame 2, a
ball tensor 48 is provided at a yarn introducing side of the gate tensor 49, and the
gate tensor 49 and the ball tensor 48 are provided at a bent part of a yarn path of
the second yarn Y2.
