Abstract
This invention relates to a method for producing corrugated material and processing strip material which is removed from the edges of the corrugated material during the formation process. The strip material is cut away from the corrugated material and expelled at a variable line speed to a trim processing machine. The line speed is measured by a sensor which provides a signal representation of the speed to a cutter assembly. The cutter assembly cuts the strip material at a cutting speed which is sequenced to the line speed such that the strip material is cut into a plurality of pieces. The pieces are generally uniform in shape and size across variations in the line speed as the cutting speed is synchronized with the line speed.
