Abstract

An in-mold label dispenser (22) for a blow molding machine is disclosed as including a dispensing head (56) mounted for rectilinear movement along a first axis A between a label magazine (48) and an open mold (28) and having a label carrier (58) mounted on the dispensing head for rectilinear movement between retracted and extended positions along a second axis B transverse to the first axis A. Rectilinear movement of the dispensing head (56) along the first axis A and coordinated extending and retracting rectilinear movement of the label carrier (58) along axis B transfers a label (50) from the magazine (48) to the mold (28) in preparation for the blow molding operation. The label dispenser (22) has particular utility when provided with a pair of the label carriers (58) to simultaneously transfer a pair of labels (50) to the open mold (28) within the confined space limitations involved. A drive linkage (66) is driven by a first gear unit (72) to reciprocally move the dispensing head (56), while a second gear unit (106) rotatably drives elongated supports (92) which mount the dispensing head (56) for its rectilinear movement and drive cams (108) that move the label carriers (58).
