<p>Process and apparatus for the continuous production of plugs of detergents consisting of the combination of at least two primary plugs of different colours. The apparatus comprises at least two extruders (2) conveying the detergent pastes through perforated grids (9) into converging nozzles (5) extended by at least one nozzle (7) ensuring the juxtaposition of the primary plugs before they pass through the exit die (23) for the final plug. The process and the apparatus make it possible to obtain bars of detergent with inlaid patterns in the bulk, these patterns remaining present therein throughout their use. <IMAGE></p> |
