Abstract
A resin bonded glass fiber grating adhesively bonded together in unitary construction to form a lightweight, high strength industrial grating, which may include a non-skid elastomer surface and the capability to be rolled up for storage and a method of constructing the same.
Claims2
Apparatus for manufacturing grating from elongate polymer bonded fiber beams having a width greater than thickness and dowel rods, the beams having holes through the thickness spaced so as to permit said holes to be aligned, comprising:
- means for supporting a plurality of said beams in spaced relationship with the widths in substantially parallel vertical planes, the dowel rods extending through aligned holes in said beams to form a loosely assembled grating;
- a heating zone for heating the beams and dowel rods;
- a gluing zone including means for applying a predetermined amount of glue to each beam-dowel rod intersection;
- and
- means for moving a lossely assembled grating in stepwise fashion for positioning each intersection of beam and dowel rod in the heating zone and in the gluing zone.
