PURPOSE:To make various patterns elaborately, quickly and inexpensively, by incorporating a flexible magnetic sheet in a cylindrical frame of a magnetic material, injecting a solvent-resistant liquid plastic into the frame, and allowing said plastic to solidify. CONSTITUTION:A design roll 10, that is, a master pattern is made of wood, plaster, clay, plastic, metal, or the like, and a roll core 11 is put in the center of the roll 10. A relief on the surface of the roll 10 is formed by manual carving, photo etching or the like. Then the roll 10 is fixed in a mold 12 of wood or metal, and an epoxy resin, rubber or melted metal 13 is poured into the space between the roll and the mold and is allowed to solidify so that two concave molds 14a, 14b may be obtained. Then after the roll 10 is removed, the concave 14a, 14b are reunited, the roll core 11 is put in the center, and an uncured liquid rubber or resin 15 is poured in the space surrounding the roll core and is allowed to solidify. Thereafter the concave molds are removed so that a painting roll 16 capable of transferring a desired design can be obtained. |
