Abstract

Procedure and device for the production of a hollow body with profiled contours and/or with variations in wall thickness based on organic thermoplastic synthetic material, in which the synthetic material is extruded in plasticized state from an annular nozzle against a removal equipment, and then, by moving the removal equipment away from the annular nozzle, when the extrusion of the synthetic material continues, a tube-shaped pre-molded body is produced, which is then blown into a wall mold that determines the wall of the hollow body, depending on the wall thickness of the previous molded body, among other things, on the three magnitudes of the device: on the amount of material leaving per annum from the annular nozzle, on the cross section of the annular nozzle and on the withdrawal speed of the withdrawal equipment moving away from the annular nozzle and other quantities, and a variation of two of the quantities that determine the wall thickness of the preformed body during the production of the preformed body is carried out correspondingly to the desired profiled contours and/or to the desired variations in the wall thickness of the hollow body, one of these two quantities being subject to variation one of the three magnitudes of the device, characterized in that the two magnitudes subject to variation are in each case one of the three magnitudes of the device: amount of protruding material, cross section of the annular nozzle and withdrawal speed.
