ABSTRACT:
To provide a yarn heating apparatus offering greater heating efficiency and ease of manufacture than a conventional yarn heating apparatus. Provide two heating spaces for yarn, and make the middle heating part 13a between these two heating spaces 10a, 10b detachable. By doing this, yarn can be heated sufficiently and the heating unit can be manufactured more easily. Place heating units 17, 17 on both side of the heating space 10a, 10b through which the two yarns will pass. By doing this, heat is radiated from both sides of the heating space 10a, 10b towards the yarn, heating the entire heating space uniformly. Taper the heating space 10a, 10b towards the yarn inserting port and make the wall facing the heating space 13a, 13b flat. This makes it easier to manufacture the wall.
