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.
