A 1931 paper by John M. Washburn of the Merrow Machine Company on the butted seam, an overedge-stitched seam that joins the ends of piece goods flat, end to end, during finishing. It defines the one- and two-thread types, lists the seam's properties (thin, elastic, dries with the goods, little waste), and describes advantages in processes such as dyeing, fulling, drying, shearing, printing, calendering and napping. Separate sections cover woolens and worsteds, cotton, silk and rayon finishing. Four photographs show the seam types.
