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.

A preform heating device comprising:
- a carrying path along which a preform is carried in a state that an axial direction thereof is vertical;
- infrared heaters disposed horizontally and spaced apart in said axial direction of said preform carried along said carrying path;
- a rotating means for rotating said preform;
- a first insulating plate disposed vertically, said first insulating plate and said carrying path being disposed facing each other with said infrared heaters between;
- a second insulating plate disposed more remotely from said infrared heaters than said first insulating plate;
- an insulating air layer formed between said first and second insulating plates;
- support members for supporting each of said infrared heaters;
- and
- a height adjustment means for allowing the height of said support members to be moved in the vertical direction with respect to said second insulating plate, and fixing said support members to said second insulating plate in a given vertical position.
