Abstract

Improvements in apparatus for the manufacture of continuous toothed strips, characterized by comprising a fixed shoe provided with a nozzle for the injection of plastic material therethrough, and a rotating element provided with a series of interconnected molding cavities; said element is arranged in relation to the shoe in such a way that, when rotating, the cavities are successively aligned with the nozzle; the mentioned shoe forms contact with the element around the aligned cavities.
