Concluding part of an 1874 Engineering article on machinery for spinning silk waste, built by Greenwood and Batley of Leeds. The text describes the later stages: drawing, roving with a screw gill and flyer, spinning, doubling or twisting, and reeling into hanks. Engraved plates show the spinning frame, screw gill roving frame, silk-drawing machine and power reel. It closes with the uses of waste-silk yarn in weft, ribbons, velvet, satin and sewing threads.
