The present invention relates to a separately coupled extrusion roll die which determines the profile of an extrusion material like rubber and, more specifically, to a separately coupled extrusion roll die which reduces the manufacturing costs by being easily replaced according to the profile of a rubber extrusion material. The die comprises: coupling units (1a, 1b) formed on both sides and a central cylindrical roll (2) which has various roll profiles (2a) integrally connected to the coupling units (1a, 1b). In the central cylindrical roll (2), divided rolls (2b) are coupled to each other by the medium of an irregular unit (3) and the divided rolls are firmly fixated by coupling a coupling unit to the irregular unit (3). |
