ABSTRACT OF THE DISCLOSURE Process for the production of alveolar modules comprising rows of parallel channels, certain of which issue onto the sidewalls of the module, wherein it consists of producing the module by extrusion using at least two independent systems, each producing rows of identical channels, whereby the formation of one of the systems is interrupted when the rows of channels being produced is to issue onto the sidewalls of the module. The apparatus for performing this process comprises a first extrusion system incorporating first extrusion material supply means and a first spinneret complementary of the cross-section of the rows of channels issuing onto the sidewalls of the module and a second extrusion system incorporating second extrusion material supply means and a second spinneret complemen- tary of the cross-section of the other rows of channels, the first and second supply means being controlled independently of one another.
