Apparatus for the production of tubular bodies |
摘要 |
In an apparatus for the production of tubular bodies such as tubes from a foil strip including a weldable plastic material, the longitudinal edges of which are welded together between two endless belts under the effect of heat and pressure with subsequent cooling, part of a belt runs against a mandrel in which individual portions thereof can be set to different temperatures to provide for selective control of the belt in order to increase the rate of production.
