초록

An apparatus for forming frangible score lines in rigid plastic sheet material. The apparatus utilizes a flat surface having a serrated edge having points and notches. The rigid plastic sheet material is laid on the flat surface. A scoring means is positioned to strike downwardly on the sheet material whereby the points of the serrated edge of the flat surface will extend into the sheet material a distance further than the notches of the serrated edge to thus form a corrugated fracturable score line in the plastic sheet material. The apparatus is useful ...
