Abstract (en)

Easy detachment of a yarn contact member and reduction of power consumption are both achieved. Yarn contact members 54a and 54b are detachably attached to respective concave grooves 53a and 53b which are defined by a heating member 52, extend along a predetermined extending direction, and are open on one side (i.e., downward) in an up-down direction orthogonal to an extending direction. Lateral heat insulation members 71 and 73 and a central heat insulation member 72 are provided to be aligned in a base longitudinal direction. Gaps between the central heat insulation member 72 and the lateral heat insulation members 71 and 73 constitute yarn guide passages 58a and 58b through which yarns Ya and Yb are guided to the respective two yarn contact members 54a and 54b attached to the two concave grooves 53a and 53b. At an opposing area 59a (59b) opposing each of the concave grooves 53a and 53b in the up-down direction, a central heat insulation member 72 is provided. The central heat insulation member 72 provided at the opposing area 59a (59b) is detachable.
