SYSTEM FOR MANUFACTURING CONJUGATE YARN AND METHOD FOR DOUBLING CONJUGATE YARN USING SAME

摘要

The present invention relates to a system for manufacturing conjugate yarn comprising yarn doubling devices, comprising: a pressure generation means; a pressure providing portion comprising a valve capable of being turned on/off to provide the air provided from the pressure generation means to the yarn doubling devices; and a pressure reducing portion provided in a channel between the pressure generation means and the pressure providing portion, wherein the pressure reducing portion comprises a pressure transfer channel and a pressure discharge channel, and a valve capable of being turned on/off is provided between the pressure transfer channel and the pressure discharge channel. If there are too many yarn doubling devices to which compressed air is not provided, thus making the control of the total pressure provided through the control of RPM impossible, the pressure provided to the remaining yarn doubling devices can be controlled to be uniform by discharging unnecessary pressure to the outside through the pressure reducing portion.
