Abstract
Grinding discs in apparatus for manufacture of pulp composed of a support disc and segments mounted on said support disc so as to form a ring. The segments are formed with ribs and grooves for breaking down the material to be ground. The outer and inner peripheral edges form together common edge lines following a wave-shaped contour line. The invention also includes a method of manufacturing segments which when annularly mounted on a support disc present wave-shaped common outer and inner peripheral edge lines.
