Abstract

A plurality of screening stations are arranged in a circular array around a continuous conveyor for advancing in step-by-step fashion a plurality of modules from station to station. A module is provided for each station and includes a holder for receiving and securing in place a glass panel for photoprocessing red, blue, and green pixels on each glass panel in the fabrication of a cathode ray tube. The glass panels are supported on each module for rotational and angular movement controlled by a drive mechanism housed on each module. A controller for initiating programmed motion of the glass panel operates the drive mechanism of each module in response to the actuation of selected magnetic switches corresponding to the operations to be performed at a specific station. The magnetic switches are actuated upon the detection of a glass panel on a module and the movement of a module is then actuated by the controller to execute a programmed tilt and spin motion associated with the station in synchronization with other programmed operations to be performed at the station.
