A method for producing artificial marble having a stripe pattern comprising injecting liquid resins having different colors into a molding cell so that they are laminated to form two or more layers; then moving a comb-like tool through the laminated liquid resins while allowing the teeth to contact the bottom surface of the molding cell, then curing the liquid resins to form artificial marble, wherein, the comb-like tool is allowed to move through the liquid resins while the interval between teeth of the comb-like tool is allowed to vary. Artificial marble can be produced having a natural marble-like appearance in which the interval of stripe varies in a natural fashion or having a radial cut moire stripe pattern.
A method for producing artificial marble having a stripe pattern, comprising injecting liquid resins having different colors into a molding cell so that they are laminated to form two or more layers, then moving a comb-like tool through the laminated liquid resins while allowing teeth of the tool to contact the bottom surface of the molding cell, then curing the liquid resins to form artificial marble, wherein, the comb-like tool is allowed to move through the liquid resins while an interval between teeth of the comb-like tool is allowed to vary, to produce a striped pattern formed from an upper layer liquid resin which flows to the bottom of the molding cell.
A method for producing artificial marble having stripe pattern, comprising injecting liquid resins having different colors into a molding cell so that they are laminated to form two or more layers, then moving a comb-like tool through the laminated liquid resins while allowing teeth of the tool to contact the bottom surface of the molding cell, then curing the liquid resins to form artificial marble, wherein, the comb-like tool is allowed to move while allowing a bleeding forming means moving therewith to contact a bottom surface of the molding cell following the track of the teeth of the comb-like tool.
An apparatus for continuously producing artificial marble, comprising a molding cell which moves, a liquid resin supplying means for laminating liquid resins having different colors to form two or more layers on the molding cell, and a comb-like tool placed so that teeth of the tool thereof are in contact with a bottom surface of the molding cell, wherein, the liquid resin supplying means has a plurality of resin discharging ports, and at resin discharging ports for resins other than the lowest layer liquid resin, distributing plates are placed so that a liquid resin flows mainly in a cell moving direction and a vertical direction thereto, and flowing to the reverse direction of the cell moving direction is prevented, and a non-stirring mixer which mixes a liquid resin and a coloring agent is placed upstream of at least one resin discharging port.
