Second installment of a serial article on fancy yarn manufacture, published in Textile World Record in February 1906. It describes the machinery and mechanisms for making knotted (boutonné) yarns: cams and clutch-driven roller sets that stop and start to form knots, mule attachments, and a frame with hollow spindles, bobbins and a ratchet-driven reel. It also covers how knot size, spacing and elongation are controlled by changing cams, gears and vibrating guide eyes or spindle rails. Figures 60-84 show the apparatus and the resulting yarn structures.
