ABSTRACT:
An in-mold label dispenser (10,10') for supplying labels to a plastic blow molding machine (12) is disclosed as having a dispensing head (36) on which a first locator (40) is mounted so as to be moveable from a withdrawn position at one side of the mold to an inserted position between open mold sections (16) and into engagement with a second locator (42) mounted at the other side of the mold. The engagement of the first and second locators from opposite sides of the mold provides accurate location of the dispensing head (36) during movement from a mold aligned position to a label transfer position to provide transferring of the labels (34) to the mold from one or more label magazines (30). First and second supports (48, 50) on which the locators are mounted are moved by first and second actuators (52,54) to provide the movement between the mold aligned and label transfer positions. A first operator (86) preferably moves the dispensing head (36) between the withdrawn and inserted positions, while a second operator (126) is also preferably provided for moving the second locator (42) between a withdrawn and inserted position. A slide assembly (96) extends between the dispensing head (36) and the first support (48) to prevent rotation of the dispensing head about the first operator (86). One embodiment of the inmold label dispenser (10) has a single dispensing head (36) which provides all of the labels from one side of the mold, while another embodiment of the in-mold label dispenser (10') has a pair of the dispensing head (36,36') for providing labels from both sides of the mold.
