INSTRUMENTATION FOR CO-EXTRUDING RUBBER MIXTURES
The invention concerns a process and apparatus for the coextrusion of rubber mixtures, comprising a main extruder ( 1 ) with an extrusion head ( 10 ) having at least two flow channels ( 14, 15 ), each for a rubber mixture (A, B), the channels opening into an extrusion orifice ( 18 ) through which th...

| description | The invention concerns a process and apparatus for the coextrusion of rubber mixtures, comprising a main extruder ( 1 ) with an extrusion head ( 10 ) having at least two flow channels ( 14, 15 ), each for a rubber mixture (A, B), the channels opening into an extrusion orifice ( 18 ) through which the two rubber mixtures (A, B) are propelled. The extrusion orifice ( 18 ) is delimited by a first wall ( 111 ) and a second wall ( 161 ). The apparatus also comprises at least one micro-extruder ( 2 ) for a third rubber mixture (C), whose extrusion head ( 22 ) is provided at its end with a nozzle ( 23 ) passing through the two flow channels ( 14, 15 ) such that the third rubber mixture (C) is inserted into each rubber mixture (A, B) upstream from the extrusion orifice ( 18 ). |
