An in-mold label transfer apparatus. In a first embodiment transfer devices mounted on an extension device comprise a pair of label applicator heads which move transversely to receive labels and to deliver same to the mold surfaces. This transfer device comprises power actuated mechanical elements including rack and pinion, cam arm scissor and scissors arrangements. Another transfer device comprises a pair of side-by-side opposed piston and cylinder units. Other embodiments include transfer arms having label transfer heads at the ends thereof, the arms comprising rods movable from a first position placing the label applicator head at the mold and a second position completely outside of the mold, and whereat the label applicator heads are positionable relative to label magazines for receiving labels. A special label applicator head constructed resiliently to resiliently urge the label against the interior of a mold surface. One embodiment includes a valve element for cutting off the suction to the label applicator head as the latter applies the label against the mold surface.
