Posselt's technical treatise on cotton manufacturing, covering the machines that follow carding: combing, drawing, roller covering and fly frames (slubbers, intermediate and roving frames). It describes the sliver lap and ribbon lap machines, Heilmann, Nasmith and Duplex combers, drawing frames from several makers, and the construction and weighting of drawing rolls.
