PURPOSE: To provide a cloth-form warmer presenting a fine appearance and assuring a good yield from the production line by furnishing a means to tentatively fasten an upper fabric material and a lower fabric material to the two outer sides of a fastening part in a long, thin shape.

CONSTITUTION: Using tentatively fixing threads, an upper fabric material 2 and a lower fabric material 3 are continuously fastened to the two outer sides of a fastening part in a long. thin shape. After the fabrics are subjected to a surface treatment. the threads 20 are drawn off, and heat emitting wires 8 are inserted. According to this constitution, generation of dislocation or slack can be precluded under the processing to make fluff separation, shearing, etc., in which the fabric body 1 is transported by rollers. Thus a cloth-form warmer offering a fine appearance and good yield is acquired wherein there is no risk of damages such as flaws on the material, cutting marks with the shearing edges, etc.
