Abstract
An emerizing apparatus is equipped with an emergy roller having multiple beater blades about its circumference, the outer periphery of each beater blade being formed with a pair of axially extending longitudinal beater edges and a concave arcuate recess therebetween, whereby each beater edge is adapted to individually strike a textile web traveling in tensioned engagement with the roller periphery to produce a shorter and more dense napped surface on the textile web than can be achieved by a corresponding conventional emery roller operating at the same rotational speed.
