ABSTRACT:
A preform heating device has a plurality of infrared heaters disposed horizontally and spaced apart in the axial direction of a preform carried along a carrying path which carries a preform in a state that the axial direction thereof is vertical. The preform is at least rotated when facing the infrared heaters. First and second insulating plates, and an insulating air layer formed therebetween are disposed facing the carrying path with the infrared heaters between. The infrared heaters are supported by a plurality of support members. Each of this plurality of support members is able to be moved upward and downward by a height adjustment means, and is fixed to the second insulating plate at a given vertical position.
