Abstract: Apparatus for molding elastomeric articles is disclosed, the apparatus including an injection unit having an open-ended chamber in which elastomeric stock is disposable and from which such stock can be expelled, a multi-cavity mold having cavities aligned with corresponding ones of the apertures of the end plate, a device for moving the injection unit and mold relative to one another to engage the mold with the end plate, and a pneumatic venting system for evacuating fluid entrapped in each of the mold cavities preparatory to filling the latter with elastomeric stock from the injection unit. The foregoing abstract is neither intended to define the invention disclosed in the specification, nor is it intended to limit the scope of the invention in any way.
