Abstract
PURPOSE: To obtain the patterned board completely free from deformation otherwise caused by expansion or contraction of a base board due to heating or cooling by passing the base board through a broader section of the die adapted to grow gradually broader in the heating zone while through a narrower section thereof adapted to grow gradually narrower in the cooling zone.
CONSTITUTION: In the base board made of a synthetic resin, side rims 1b are hung on each side of a surface plate section 1a. The pattern 3 printed on the surface plate section 1a is foamed by heat on the base board 1 being carried fitted into a belt- shaped die 2 and then, the board is cooled to produce a board having the foam pattern on the surface plate 1a. In this process, the base board 1 is passed through a broader section 2b of the die 2 adapted to grow gradually broader in the heating zone X while through a narrower section 2c of the die adapted to grow gradually narrower in the cooling zone Y. That is to say, the base board is maintained in the shape closely fitted into the die regardless of expansion and contraction thereof thereby eliminating deformation from the foam-patterned board.
