Abstract

Moulds for making annular polymeric articles, partic. flat endless rubber toothed belts, comprise (a) a core having an outer contoured surface for placing a workpiece thereon; (b) two half-moulds having holes for discharging excess polymer and embracing the contoured surface of the core and partially embracing end faces of the core during press-forming of the article, and (c) means for pressure-sealing a forming interior of the mould; such that (d) the half-moulds have in the area where they are joined a width equal to the length of the generating line of the core; whereas (e) the means for pressure-sealing the forming interior includes two members rigidly attached to one of the half moulds at the opposite sides thereof and having each at the side facing the half-moulds the form of a portal embracing these half-moulds in the area where they are joined and embracing part of the end faces of the half-moulds and core during press-forming of the article.
