Roving

 

a semifinished spinning product from which yarn is made. It is the intermediate product between sliver and yarn. The fibers in the roving are slightly straightened and rather uniformly arranged throughout the length of the roving. The roving is produced on roving frames by means of a slight twisting (in the spinning of cotton and bast fibers and the worsted spinning of long wool) or doubling (in the condenser spinning and worsted spinning of fine wool) of the fibrous sliver. In this way, the product acquires the form of coarse thread, is made more dense, and receives the strength necessary for winding and unwinding; the added strength also allows the roving to be drawn out on spinning machines without harming the fibers. The chief requirement for roving is uniformity of thickness and structure.
