An in-mold labeling apparatus is disclosed 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 blow molding machine comprising: a blow molding wheel having a plurality of molds at its periphery each having two separable segments and said wheel being rotatable on an axis; guide track means forming a closed circuit and disposed to register at least in general parallel alignment with a path travelled by a mold on said wheel for a discrete distance; plural carriages on said guide track means; driving means including wheel driving means and carriage driving means for simultaneously and synchronously driving said wheel and said carriages through said discrete distance at zero relative velocity; a label suction means on each carriage to grasp a label from a source of supply adjacent the guide track means; and means to move said label suction means and the label into the adjacent mold part while moving through said discrete distance at said zero relative velocity.
