Abstract

An apparatus for forming tubular tile, including an endless trackway having at least two substantially straight portions defining first and second molding sec-tions, a plurality of mold blocks supported for movement about the trackway, and a plurality of mating mold blocks supported for mating with the first mold blocks along each molding section to form a segment of a corrugated molding tunnel. Extruders introduce moldable material at the be-ginning of each molding section, and the material is con-formed to the molding tunnel along the molding sections for forming the tile, with the mold blocks being separated when they move past the end of each molding section. The ex-truders are mounted for movement toward the beginning of the two molding sections when initiating tile formation therein. A plurality of mold assemblies each support a pair of mold blocks for movement about the trackway, and the mold blocks are supported thereon for pivotal movement about an axis extending substantially in the direction of movement of the mold assemblies about the trackway. Roll-ing followers associated with each of the mold blocks and a cam surface associated with the trackway cooperate to position the mold blocks as desired throughout their move-ment.
