A dictionary entry on the flax-brake, a machine for breaking away the woody portion of retted flax stalks from the fiber. It traces the development from beating flax with a stick, through the sword-and-slat brake with treadle and spring-pole, the toothed-jaw brake, and the three-roller brake, to a five-roller fluted iron machine. It also describes a continuous machine (Fig. 2017) with drawing, scutching, cleaning and picking cylinders, and notes a second sense of the term as a machine for shortening flax staple.
