A 1929 survey article by H. Wagenknecht on mechanical ways to raise loom output in the weave room. It covers weaving several cloths side by side or one above another, larger shuttles, automatic bobbin changing, nipper shuttles, and shuttleless looms using clamps, reachers and shears to insert filling from large cones. It ends with a double-shed system using a comb in place of the reed and half-heddles, and uses diagrams to compare the methods.
