摘要

A thin springy serrate steel strip is bent to the shape of the character, and the teeth are pressed into a support plate comprising a hard rubber layer on a metal layer, so that the shaped strip is at right angles to the support plate. The assembly may be inverted, laid on a base, and molten material poured through holes through the rubber/metal support plate.
