IMPREGNATION TANK FOR IMPREGNATING A FABRIC AND A DEVICE FOR MANIFACTURING A CYLINDER FOR A PRINTING MACHINE WHICH INCLUDES SAID IMPREGNATION TANK

摘要

The impregnation tank (1) for impregnating a fabric (3) comprises an impregnation roller (2) for impregnating the fabric (3) with the resin, a chamber (6) that can be filled with a resin and that extends all around the impregnation roller (2), an entrance channel (7) for the fabric (3) to enter said chamber (6) and an exit channel (8) for the fabric (3) to exit said chamber (6), the impregnation roller (2) having ridges (9) on the external cylindrical surface so as to delimit uniformly distributed storage cavities (10) for the resin, the chamber (6) having an impregnation zone (11) for impregnating the fabric (3), a regeneration zone (12) for regenerating the resin in the storage cavities (10), a first connecting zone (20) connecting to said entrance channel (7), a second connecting zone (21) connecting to the exit channel (8), the first and second connecting zones (20, 21) being interposed between the impregnation zone (11) and the regeneration zone (12), the regeneration zone (12) being smaller in volume than the impregnation zone (11).
