Kind Code:
A
Abstract:
A rotary cylinder for heat-treating a web bearing against its outer surface is heated by an internal stationary assembly of IR burner modules that heat lengthwise distributed annular bands of the cylinder, the burners having air-fuel mixture supplies that are regulated by cross-machine sensing of the web for controlling the web's cross-machine profile characteristics, the cylinder being part of a machine comprising a succession of like IR-burner-heated cylinders operated at respective optimal temperatures. The assembly of IR burners is removable from an end of its cylinder for service or modification. The interior of the stationary IR burner structure is protected against undue heat build-up.
