Mechanized finishing devices designed to raise the nap of woven fabrics by brushing the surface of the fabrics with teasel heads. To automate the teasing process, these devices comprise a large quantity of prickly teasles fastened to iron frames and attached to two drums. The drums rotate as woolen fabrics are fed between them, drawing out the ends of the fibers and producing a fuzzy finish to the fabric's surface. The teasing process accomplished by these devices represents one of the final processes in woolen cloth production.
