ABSTRACT:
This invention is a low profile, over-under conveyor with two continuously moving chain loops that form upper and lower tracks on which flexible work platforms ride. Each flexible platform includes two or more spaced metal slats joined by a thin flexible band. The slats include shoes that rest on and frictionally engage the moving chain loops. When one of the platforms reaches the end of one track, the flexible platform frictionally engages and compresses a pneumatic drive wheel and flexes to negotiate a low profile inversion and return on the other track. This allows the conveyor to handle long work platforms, while having a relatively low profile. Asynchronous accumulation and release of the freely moving flexible work platforms is accomplished using stop cylinders mounted inside the frame of the conveyor.
