Abstract

The rod for a grating has at least two rows of ribs (1), triangular in section which run spirally around the core of the rod (2) forming parallel turns. The ribs are interrupted by gaps (3), the height of the ribs varying along their lengths so that, at any section through the rod, the overall dia. is the same. The cross sectional shape of the core can be polygonal, and the angle of the tip of the rib can be a right angle.
