ABSTRACT:
Apparatus for removing partially exposed, upstanding, plug-like, cured scrap from sprues of a mold is disclosed. The scrap is integral with and separable from cured elastomeric product formed in respective mold cavities of the mold at corresponding sprue constriction regions of minimum cross-section. The apparatus comprises a wiping assembly engageable with the exposed portions of the scrap, and a system for moving the mold and wiping assembly relative to one another to effect engagement of the scrap with the wiping assembly and thereby tear the scrap free from each cured elastomeric product at the sprue constriction regions of minimum cross-section.
