PROBLEM TO BE SOLVED: To continuously manufacture an artificial marble plate with excellent dimensional accuracy and high productivity as a polymerization curing device, by previously impregnating a gasket sandwiched between a pair of endless belts and fed by following to feeding of the belts with a radical polymerizable vinyl compound and using it. SOLUTION: In this continuously manufacturing apparatus, an artificial marble plate polymerization raw material mixture is continuously charged from a raw material charging unit 6 disposed at an upstream side of a continuous gasket 7 fed in the state that the gasket 7 is sandwiched between a pair of opposed endless belt faces 1, 1'. As the gasket 7, a gasket impregnated with a radical polymerizable vinyl compound is used. As the impregnating means, it is performed by dipping the feeding gasket 7 in a tank 17 of the radical polymerizable vinyl compound. After the gasket 7 is heated and cooled, the gasket is taken out from ends of the belts 1, 2' as an artificial marble plate. Thus, the plate having high thickness accuracy can be obtained.
