A thermoregulation system of rotating metal cylinders in plants for extrusion and conversion/transformation of plastic films, comprising:
- one or more heating elements applied to each rotating metal cylinder,
- wherein said heating elements are infrared heating elements,
- wherein said rotating metal cylinder comprises a metal tube rotating around a fixed shaft, which is rigidly connected to two side plates,
- wherein a plurality of said infrared heating elements is applied to said metal tube, and
- wherein said infrared heating elements are positioned circumferentially on an annular supporting structure fixed to the shaft of said rotating metal cylinder, so that said infrared heating elements are stationary and immobile with respect to the rotating metal cylinder.
A cylinder for a thermoregulation system, comprising:
- a plurality of heating elements applied to said cylinder,
- wherein said heating elements are infrared heating elements,
- wherein said cylinder comprises of a metal tube rotating around a fixed shaft, which is rigidly connected to two side plates,
- wherein said plurality of said infrared heating elements is applied to said metal tube, and
- wherein said infrared heating elements are positioned circumferentially on an annular supporting structure fixed to the shaft of said cylinder, so that said infrared heating elements are stationary and immobile with respect to the cylinder.
A method of heating a rotating metal cylinder in plants for extrusion and conversion/transformation of plastic films, comprising:
- providing a rotating metal cylinder that comprises a metal tube rotating around a fixed shaft, which is rigidly connected to two side plates;
- and
- providing a plurality of infrared heating elements, which are applied to said metal tube,
- wherein said infrared heating elements are positioned circumferentially on an annular supporting structure fixed to the shaft of said rotating metal cylinder, so that said infrared heating elements are stationary and immobile with respect to the rotating metal cylinder.
