<p>The briquet forming apparatus includes a pair of opposed, generally cylindrical forming roll assemblies (14, 16). Each forming roll assembly (14, 16) has multiple, axially spaced-apart, annularly continuous grooves (34) and multiple, axially spaced-apart, annular rows (36) of forming teeth (38). Each groove (34) has a generally semi-circular groove cross section. Each forming tooth (38) is the cusp of intersecting arcuate surfaces which are essentially concave and semi-circular in directions along the forming roll assembly circumference and essentially convex and semicircular in directions along the forming roll assembly longitudinal axis.</p> |
