This relates to a labeller for applying labels to the cavities of mold halves of a rotating blow molding machine whereby when a parison is blow molded within each mold thereof to form a bottle or like hollow article, each such article will be provided with at least one and preferably two labels. The labeller is provided with pick-up heads to pick up labels from two opposed hoppers and then move the labels in between the paths of rotation of mold halves and with proper timing advance the labels into the mold half cavities and discharge them on the walls of the mold cavities. Control circuitry is provided for the automatic operation of the labeller whereby not only can the labeller operate without interference with the moving mold halves, but also accurately position the labels within the cavities. This abstract forms no part of the specification of this application and is not to be construed as limiting the claims of the application.
An apparatus for applying labels to internal surfaces of mold cavities, said apparatus comprising a hopper for labels, a carriage, a pick-up head carried by said carriage for picking up labels from said hopper and placing such labels in open mold halves, guide means supporting said carriage for movement of said carriage along a fixed path to move said pick-up head between a first position aligned with said hopper to a second position in between the path of open mold halves back and forth positioning means connected to said carriage for selectively moving said pick-up head to a selected one of said first and second positions, and extensible means carried by said carriage for selectively moving said pick-up head between a retracted position and label engaging and discharge positions.
