Claims

[Scope of utility model registration request]

(1) A belt in which a plurality of protrusions protrude from the belt base belt along the belt longitudinal direction, wherein an intermediate hard rubber layer is provided at the intermediate portion in the height direction of the protrusions, and a tip soft rubber layer is provided at the tip portion. Rubber layers are arranged, and the intermediate hard rubber layer has short fibers having an elastic modulus of at least 800 kg/rran" arranged in the belt width direction, while the tip soft rubber layer has short fibers arranged in the belt width direction. A multi-protrusion belt characterized by being arranged in.

(2) The multi-protrusion belt according to claim 1, wherein the short fibers of the intermediate hard rubber layer are cotton fibers.

(3) The multi-projection belt according to claim 1, wherein the short fibers of the intermediate rigid comb layer are polymetaphenyl isophthalamide fibers.

(4) The multi-projection belt according to claim 1, wherein the short fibers of the intermediate rigid comb layer are polyparaphenylisophthalamide fibers.

(5) The multi-protrusion belt according to claim 1, wherein the intermediate hard rubber layer has a comb hardness 2° or more greater than other parts constituting the protrusion.

(6) The multi-projection belt according to claim 1 or 5, wherein the intermediate hard comb layer is formed by mixing 7 to 30 parts by volume of short fibers with respect to 100 parts by volume of the rubber compound. .

(7) The thickness of the intermediate hard rubber layer is -1 of the protrusion height.
4 to 45%, and from the tip of the protrusion to 45% of the protrusion height.
A multi-protrusion belt according to claim 1, 5 or 6 of the utility model registration claim, which is separated by a length corresponding to 85%.

(8) The multi-protrusion belt according to claim 1, wherein the tip soft rubber layer is formed by mixing 5 to 30 parts by volume of short fibers with respect to 100 parts by volume of the rubber compound.

(9) The multi-protrusion belt according to claim 1 or 8, wherein the soft comb layer at the tip has a rubber hardness that is 3° or more smaller than other parts constituting the protrusion.
