Abstract:
1. A modular cutter bed comprising: a series of interconnected modules provided with individual rotary cutters having upright axes of rotation, each module having a pair of opposite ends abutting the ends of adjacent modules to present a series of fore-and-aft seams along the cutter bed between the modules; and a series of guards presenting a substantially continuous, scalloped front extremity of the cutter bed comprised of alternating convex segments and concave notches wherein the notches are aligned with the seams between adjacent modules and the convex segments are aligned with the axes of rotation of the cutters, each guard spanning the seam between a pair of adjacent modules and being secured to both modules of the pair, adjacent guards in the series having fore-and-aft side edges disposed adjacent one another in the convex segments of the front extremity of the cutterbed to present fore-and-aft joints that are located in the convex segments in front of the axes of rotation of the cutters, said guards being devoid of fore-and-aft edges in the concave notches of the front extremity of the cutterbed such that the notches are joint-free in front of the seams between adjacent modules.
