MACHINE FOR THE PRODUCTION OF TUBULAR BODIES

摘要

The invention relates to a machine for the production of tubular bodies. The inventive machine comprises a decoiler (1) having numerous coils (5) installed therein, said coils being mounted on respective independent shafts. Next, the invention comprises a heating tunnel (9) which is assisted by a hot air generator (12) which is disposed in a lateral, oblique position. According to the invention, bands (5) arrive at the front end of a fixed mandrel (10) in both the angular and axial directions, said support being cantilever mounted to a support (15) at which the above-mentioned bands (5) arrive in a tangential oblique manner. Moreover, the bands are driven by a flat belt (14) which causes the bands to slide, said bands being partially disposed on top of the mandrel (10). The mandrel is cooled in order to facilitate the fast welding of the plastic and is assisted by a softening-liquid-impregnation device in order to facilitate the sliding of the tubular body obtained on the mandrel. The continuous tubular body thus obtained is divided using a cutting device which is located beyond the outlet end of the mandrel (10).
