Abstract: A label transferring apparatus useable for in-mold label application. In a first embodiment, a transfer device is mounted on a pivotable radial arm and comprises two pairs of transfer heads mounted for rapid, reciprocal transverse movement. A stack of labels is supplied by corresponding two pairs of magazines located at a first radial position. The radial arm is positioned by a fluid actuated rack and pinion mechanism.

Abstract: 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.

Abstract: A label transferring device which places labels simultaneously in separate sides of a mold used in blow molding machines. A hydraulic cylinder has a carriage assembly mounted to the piston rod so as to be extended between the separated mold sections and retracted to a position between a set of label supply magazines. The label supply magazines are positioned so that a set of opposed carrying cylinders can extend and pick up the labels on carrying heads and place the labels on the placement areas in the mold. Alternatively, the carrying cylinders are mounted on a pair of extendable, converging clamp arms which clamp onto the molded objects, remove them from the molding area and transport the objects to other processing stations in the machine.

Abstract: A label transferring apparatus useable for in-mold label application. In a first embodiment, a transfer device is mounted on a linear actuator having a piston rod extending out a first end and carrying the label transfer device and extending out the other end whereat it is supported on a track means. A stack of labels is supplied by corresponding two pairs of magazines located at a first radial position. In a second embodiment the linear actuator is mounted so as to be cantilevered back over the forward end of the piston and cylinder which comprises the linear actuator. In this embodiment the piston and cylinder may be shortened by excluding that portion of the piston rod extending out the other end of the cylinder.

Abstract: The label transferring device for placing labels in a separable mold of a blow molding machine which includes a pair of movable platens which converge the mold portions and also move in unison to different blow molding stations of the machine. An articulating arm is mounted directly on one of the platens and includes a vacuum section head to transport the labels. The articulating arm moves the carrying head from a label supply magazine which is also mounted on the platen to a labeling position between the molds, so that both the articulating arm and supply magazine are carried by the platen as it moves to different blow molding stations. Preferably, an articulating arm having a plurality of carrying heads is mounted on each platen along with a label supply magazine.
