Abstract

PURPOSE:To extrude a base material and a coating film and at the same time simplify the construction of an extruder by forming an injection outlet at a required position on the inner face of an orifice used for determining the shape of the extruded base material. CONSTITUTION:A material flow route 19 is provided for a coating material 2 so that the outlet 18 of the flow route 19 is positioned at a required location on the inner face of an orifice 11 that is to determine the shape of an extruded base material 1. Since this construction does not require a conventional separate orifice for the coating material 2, it is simplified and it is not necessary to make the outlet 18 small and the pressure to extrude the coating material can be set at a small pressure with the result of a thin film coating of 0.01-0.05mm.. Because of the simplicity of the device, it is suitable for the manufacture of products with a complicated cross section such as weather strip, etc.
