  • Multi-channel co-extrusion preformer having a monolithic through stiffener which can be obtained by additive manufacturing
    Patent number: 11969933
    Abstract: A preformer (1) is designed to extrude jointly a plurality of elastomer mixes in a direction of flow (X1), in order to form a profiled element, the preformer comprising for this purpose, superimposed in a direction of stacking (Z1), transverse to the direction of flow (X1), a first channel (11), a second channel (12) which is separated from the first channel (11) by a first partition (15), then a third channel (13), separated from the second channel (12) by a second partition (16), the preformer also comprising a stiffener (20) formed integrally with the first partition (15) and the second partition (16), and extends through the second channel (12), having a leading edge (21) which splits the flow of elastomer material following the second channel (12).
