Abstract
An apparatus for producing small molded bodies with overhanging portions, e.g. for use as end stop members in slide fastener stringers, wherein a molding band is fed to a forming wheel to define individual molding cavities therewith, the cavities passing to a molding station at which a synthetic resin material is injected into the cavities. According to the invention, the band consists of a plurality of band members which upon being fed to the wheel, form a core with undercut formations around which the synthetic resin material is molded and, following molding, the band portions are laterally or orthogonally offset to release the articles drawn by the band out of forming beds on the wheel.
