| 摘要 |
The invention utilizes forced air heating in which heated air is fed through tubes to a mold or form shaped substantially like a human foot. The mold or form has apertures or holes which are patterned to provide heat to the insole and/or tongue, heel, counter, midfoot, arch, and toe box. The size of the holes can vary in size as can the quantity depending upon how much heat is needed by a specific area. Panels may be provided in the mold or form to regulate the amount of air flow to a given area. Where insoles are the main item being formed, the insole must be beveled before it is molded because the material has a tendency to expand to its original thickness upon heating. Beveling the edges of the insole before it is premolded prevents the insole from expanding around the edges when the insole is molded to a person's foot.
