ABSTRACT:
Track sections of industrial conveyor systems are joined in end-to-end relationship using alignment devices that ensure that the internal running surfaces of the rail flanges of the track are free from irregularities at the track joints. Tubular bushings are located at the ends of the sections on adjacent external surfaces of the rail flanges out of running contact with the moving conveyor components. When the bushings are brought into register and united to form a connection, proper alignment is achieved and maintained without the need to weld the track sections together at each joint. This provides a modular track configuration to facilitate the installation and maintenance of conveyor track systems.
