| 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
). |
