An in-mold labeling apparatus for a blow molding machine having a primary circular multiple mold path. A continuous drive closed circuit is provided by a guide track means and forms a secondary path in which a carriage or trolley carrying an air actuated means for picking and holding a label for transport to a matched segmental transfer station at which the mold parts and the carriage move in unison at zero relative velocity during which the label is automatically deposited in a mold for application to the plastic part being formed by the mold. Thereafter, the carriage or trolley is conditioned to pick up another label. The continuous driving of both the blow molding machine and the in-mold label dispenser is synchronized for unison uninterrupted operation.

A label transporting and dispensing apparatus for use in a blow molding machine having at least one mold pair made up of two mold halves, each mold half having at least one respective mold cavity which accepts material to be molded when the mold halves are in a first open position and the material is then molded into a desired shape when the mold halves are in a second closed position comprising: at least one pair of mold halves; a label dispenser capable of dispensing two labels simultaneously; at least two transport chains separated a predetermined distance; at least one trolley affixed to said transport chains and having at least two rotatable turret label engagement assemblies each having at least one air controlled suction cup member capable of engaging, grasping and releasing a label from said label dispenser, each of said turrets having at least one guide arm; a guide track means for accepting said guide arms and said transport chains and for providing movement of said transport chains and said at least one trolley said guide track means being positioned between said transport chains, said guide track means having at east three sections, a first of said at least three sections comprising a matching segment positioned between an arc segment through which said mold pairs move in their open position and a second of said at least three sections being positioned adjacent said label dispenser, each of said sections having a respective means for engaging said guide arms of said turrets and for providing positioning of said label engagement assemblies of said trolley; and air suction label retaining means within each of said mold cavities of said mold halves; whereby each of said label engagement assemblies engages and grasps a label from said label dispenser, the labels are transported to a position within each mold cavity of at least one respective pair of molds in their open position by said transport chains, the label engagement assemblies and the labels moving through said matching segment at zero relative velocity with respect to the mold parts for positioning the labels within said mold cavities, said labels are simultaneously released from said label engagement assemblies and are retained in the mold within said mold cavities by said label retaining means and said label engagement assemblies are transported back to said label dispenser to repeat the cycle.
