The invention further provides contoured electrifier apparatus which is adapted for use in the polishing of three dimensional deep pile surface contoured fabrics and the like. In addition, the invention provides ways of adapting the control system for use with a plurality of transversely extending processing units, each one of which can have transversely varying process conditions such as required in a contour shearing device or contoured electrifier.Other References
