A conveyor system for rapidly moving and simultaneously processing material sheets through several processing stations, the conveyor system including a chain that moves in an endless loop, and noncontiguous operational and standby skid sections for supporting material sheets and moving with the chain in the endless loop; wherein the conveyor indexes through the processing stations, such that, after each indexing, the conveyor has one skid section that is in operational position associated with each of the processing stations, thus allowing each of the processing stations to operate simultaneously on the associated skid section, during each time period when the conveyor is stopped, after each indexing.
