It's cut by puncher from reinforcing netlike fiberglass cloth for
grinding wheel. The cloth was coated with phenolic resin and epoxy
resin, and then was baked.

with adhesive-bonded fabric and nets coated with black paper. The
other type is pure net.

wheel which adopts resin as adhesive agent. The grinding wheel which
is made with this basal material has properties of excellent heat
resistance, cutting at high speed and great structural strength.
