The fundamental system of making yarns for woolen fabrics. In yarns spun on the woolen system, the fibers are not parallel but are crossed in what appears to be a haphazard arrangement. After blending, fibers produced on the woolen system are evenly distributed in carding on two, three, or even four cards. From here, the split web, called roving, goes to the spinning frame. In addition to wool, manufactured fibers, cotton, wastes, and noils can be processed on the woolen system. In general, the fibers used are shorter and more highly crimped than those used on the worsted system and are of the type that can be fulled.
