The knife blade holder includes a holder block having formed therethrough a threaded hole through which the knife adjusting bolt is adjustably inserted. The holder block has a first support surface that is in supporting contact with a part of one surface of the knife blade on the side thereof where a bevel face of the knife blade is formed and a second support surface that is in supporting contact with a part of a base end surface located opposite from and extending parallel to a cutting edge of the knife blade.
Claims19
A knife assembly comprising,
- a single cutting edge consisting of a single knife blade having a thickness, first and second blade surfaces across the thickness, a bevel surface formed on the first blade surface side of the single knife blade, a cutting edge formed by the second blade surface and the bevel surface, a base end surface located opposite from and extending parallel to the cutting edge,
- a plurality of knife blade holders including respective holder blocks each having a first support surface configured to contact with a part of the first blade surface of the single knife blade and a second support surface configured to contact with a part of the base end surface of the single knife blade, each holder block having therethrough a threaded first hole formed extending in a direction perpendicular to the second support surface of the holder block, the holder block being removably fixed to the single knife blade, said plurality of knife blade holders being disposed with predetermined intervals therebetween relative to and in a longitudinal direction of the single cutting edge of the single knife blade,
- a knife adjusting bolt adjustably inserted through each threaded first hole,
- a lock nut that releasably fixes each knife adjusting bolt to each holder block;
- and
- wherein the knife blade has therein a plurality of cuboid recesses aligning parallel to the cutting edge at predetermined intervals therebetween, each cuboid recess being recessed from the base end surface toward the cutting edge and having a surface extending parallel to the cutting edge and forming part of the base end surface of the knife blade, whereas said holder block of each knife blade holder has a cuboid shape formed with a complementary portion including a cuboid void portion to receive part of said knife blade and a cuboid solid portion adjoining said cuboid void portion, said cuboid solid portion being sized to fit in each cuboid recess in said knife blade, said cuboid solid portion providing the second support surface to support the knife blade at said surface in the cuboid recess thereof.
