  • Patent number: 4639207
    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.

  • Patent number: 4479771
    Abstract: An in-mold label dispenser (10) is disclosed for supplying labels to a multiple cavity blow molding machine (12) for an in-mold labeling process. Label dispenser (10) includes a dispensing head (24) mounted for movement between a withdrawn position free of the mold and an inserted position between mold sections in an open position of the mold. A plurality of label carriers (26) are mounted on the dispensing head (24) for movement between retracted and extended positions in order to receive labels (32) from magazines (28) and supply the labels to the mold. A drive mechanism (30) moves the dispensing head (24) and the label carriers (26) for the in-mold label dispensing. Preferably, the dispensing head (24) is mounted on a support (34) and is moved in a hesitating manner to receive labels. The dispensing head support (34) is preferably mounted on a frame (38) in a manner that conserves floor space and the frame is also mounted in order to permit access to the associated blow molding machine.
