ABSTRACT:
Method and apparatus for handling a plurality of glass containers moving on a conveyor at spaced intervals to a coating application area where three containers as a group are simultaneously grasped about their side wall and retracted laterally from the surface of the conveyor. This group of containers is then moved through a 90.degree. arc such that the containers exhibit horizontal axes one above the other. After the articles are turned to the horizontal, they are moved into position between three heel and neck-engaging chucks carried by an indexible turret. The bottles are released to the chucks which are cam actuated in timed relationship with respect to the grasping means so that the grasping means will release the containers or bottles to the chucks. With the chucks holding the bottles in horizontal position, the turret rotates about a horizontal axis parallel to the axes of the bottles through an arc of 90.degree. and presents the chucks in a horizontal line at the bottom of the turret. In this position, a shoulder coater mechanism, which is also cam operated, will be elevated into contact with the shoulder portion of the containers and the containers rotated through at least 360.degree. of rotation about their axes. The coating mechanism is retracted and the turret indexed through another 90.degree. arc will bring the containers to the unloading side of the machine where they are grasped by a second set of three side wall-engaging jaws or grasping means. After grasping the containers and pulling back from the chucks the grasping means are rotated about a horizontal axis normal to the axes of the containers so as to revert the containers to an upright position. When in this position, the grasping means are moved forward, at which time they release the containers to an exit or continuously moving conveyor moving away from the application area.
