Abstract:
1. A method for continuously producing an artificial marble plate comprising: feeding a raw material compound for the artificial marble plate to a space defined by upper and lower carrier films facing each other and a pair of gaskets disposed at horizontal edges of the upper and lower carrier films; and heating upper and lower surfaces of the raw material compound at the same temperature by the same heat transmission manner to harden the upper and lower surfaces of the raw material compound at the same rate, via a pair of upper and lower horizontal heating plates symmetrically disposed on the upper and lower surfaces of the raw material compound, supported by a frame and receiving the upper and lower carrier films into a gap therebetween, each including temperature controlling means and heating means for heating upper and lower surfaces of the raw material compound, wherein the upper heating plates are in contact with the upper carrier film and the lower heating plates are in contact with the lower carrier film, while moving the upper and lower carrier films along a gap between the upper and lower horizontal heating plates, wherein heating is done without pressing or pressure.
