High-speed mechanized devices used to tighten the weave of linen materials and produce the fabrics' characteristic sheen and lustre. These devices are comprised of a heavy frame supporting a large quantity of hardwood faller stamps, metalweights, mallets, or hammers that are operated by cams attached to a horizontal shaft. The linen is typically dampened then wound on an iron cylinder directly beneath the hammering devices, which rapidly pound the fabric to prepare it for washing, calendising, and/or dyeing. These devices constitute the last major step in the linen manufacture process.
