Abstract
Method and device for the manufacture of a tube based on synthetic material, in which an almost liquid molded body is extruded from an extrusion molding tool with a tool mandrel and the molded body is removed through an internal calibrating mandrel connected to the tool mandrel and at the same time it is cooled from the almost liquid state margin while a lubricating agent is introduced between the molded body and the internal calibrating mandrel, characterized in that the procedure is that in the almost liquid state margin of the body A molded hydraulic lubricant is introduced practically without pressure into a space located between the tool mandrel and the internal caliper mandrel, dragging with it the molded body a layer of lubricating agent between the internal caliper mandrel and the molded body, and why this layer lubricant is wedge-shaped in longitudinal section on the cali mandrel inner brador by radial forces acting on the molded body.
