PROBLEM TO BE SOLVED: To provide a technology for preventing sticking of a stain to a groove part of a rotary guide used for carrying a yarn material and efficiently removing the sticking object. SOLUTION: A V-groove type rotary guide is used for carrying the yarn material. The V-groove type rotary guide is provided with a continuous slit in the peripheral direction over the whole periphery of its groove bottom part. The V-groove type rotary guide is formed by communicating a cavity part with the slit by arranging the cavity part over the whole periphery in an intermediate position between the rotational axis and the slit. The V-groove type rotary guide is formed by communicating the cavity part with an external part in a place except for the slit. A method is provided for carrying the yarn material in a state of contacting the slit of the V-groove type rotary guide with a cleaning liquid. COPYRIGHT: (C)2011,JPO&INPIT
