Device for manufacturing tubular bodies

摘要

The device has a heating device exhibiting a heating bar (32) with a heating unit (33) and another heating unit (34) that is insertable in a mandrel (20). The two heating units exhibit respective heating surfaces (35) that are opposite to each other, spaced in a vertical direction, where a gap is formed between the heating surfaces. The heating units are equipped with an electrically charged thick-film resistance heater, where a form belt (21) of the device is formed as a form band and conveyor belt.
