Claim Text:
1. A method of manufacturing foam safety cones, comprising the steps of: a. using a foam mold to produce a board that is formed with a plurality of non-penetrating concave holes at least on one upper surface thereof, with a rib separating each pair of adjacent concave holes; b. taking the foam molded board out of the foam mold, and cutting the foam molded board along a horizontal line into an upper plate and a lower plate, with the cutting surface going through an upper edge of bottoms of the concave holes, so that the upper plate has a mesh formed by the ribs; c. cutting the upper plate into an expanding surface to be folded into a predetermined pillar object, with at least two sides of the expanding surface being formed with a connecting side, respectively; d. folding the expanding surface and connecting the connecting sides to form a pillar object of a predetermined shape; and e. connecting a base to a bottom of the pillar object to render a foam safety cone.
