Abstract
The present invention is directed to a seal crossover system which includes two seal plates adjacent to slot crossover portions of separate respective conveyor loops as they diverge (or converge) past a switch in a power and free conveyor system. The seal plates are driven by respective pneumatic cylinders which are pneumatically linked to a switch cylinder such that the seal plates are automatically extended or retracted depending upon the condition of the switch. Thus a respective slot crossover portion of each conveyor loop is selectively and alternately sealed or opened to allow unimpeded passage of a load carriage and a drive trolley, respectively.
