Abstract
Abstract A label applicator for an injection moulding machine which includes a suction head for picking up a label, an electrostatic charging device to electrostatically charge the label and means to reverse the suction to transfer the label to the face of a die where it is held by electrostatic forces. The label applicator also includes sensing pins which will actuate a switch to close down the injection moulding machine if the label is not correctly positioned to cover the sensing pins.
