ABSTRACT:
The device is particularly suitable for cleaning die plates. It consists of a compressible sheet of sponge plastics material, a layer of adhesive which is flexible and viscous at ambient temperature deposited on each face of the sheet and an outer covering sheet of non-woven fabric superposed on each layer of adhesive. In order to clean the die plates the sheet is inserted between the open plates of the die and compressed between the plates so as to exert an abrasive absorbent action on the die plates.
