An in-mold label dispenser for a blow molding machine includes a dispensing head mounted on a base for movement along a first path from adjacent a label magazine to between the open sections of a mold and a label carrier mounted on the dispensing head for movement along a second path substantially transverse to the first path from a retracted to an extended position. A drive mechanism is mounted in the base for moving the dispensing head along the first path and the label carrier along the second path in co-ordination with the opening of the mold. The drive mechanism includes an elongated support extending between the base and the mold sections for supporting the dispensing head as it moves along the first path and means for oscillating the elongated support about an axis transverse to the second path. A lever assembly is connected between the elongated support and the label carrier to provide movement of the label carrier along the second path for receiving a label at the label magazine and depositing it within the mold cavity. An adjustable stop assembly is provided on the label carrier for stopping movement of the label carrier along the second path after the label carrier has moved a sufficient distance into the mold section to establish a gap of predetermined width between the label and the wall of the mold cavity. The lever assembly includes a bias means which is so arranged as to permit continued movement of the oscillating support after the stop assembly has been engaged to stop movement of the label carrier, thereby preventing damage to the label carrier.
