First installment of a serial on cotton spinning from Posselt's Textile Journal, October 1907. It opens with a detailed outline of the planned ring spinning chapters, then introduces the ring frame: how it compares with the mule, the principles of drafting, twisting and winding, and a part-by-part description of a standard frame using Figs. 226 and 227. The parts covered include the creel, drafting rolls, thread board, ring rail, traveler, spindle and tin cylinder.
