Abstract: PURPOSE: A spray typed molding apparatus is provided to manufacture a product of large diameter by adopting a device for varying the movement speed of a board without requiring additional installation cost. CONSTITUTION: The spray typed molding apparatus is comprised of a rotating board(2) having a variable movement speed, and an atomizer for spraying liquid drops onto the board. The atomizer is selected among a linearly reciprocating atomizer(18) and a scanning atomizer vibrating within a specific angle region. The linearly reciprocating atomizer expands the stacking region of the liquid drops by reciprocating a turn dish(12). The movement speed of the linearly reciprocating atomizer is able to be periodically varied.
