What is claimed and desired to be protected by Letters Patent is set forth in the appended claims:
1. A saw, comprising a saw blade having an edge; and a cutting coating arranged on said edge of said saw blade and selected from the group consisting of a diamond-containing coating and a cubic crystalline boron nitride-containing coating, said cutting coating being subdivided into a plurality of individual cutting segments, said saw blade being composed of a synthetic plastic reinforced with a fiber material composed of a plurality of fibers selected from the group consisting of carbon fibers and graphite fibers with a volume fraction of 30-70%, said cutting segments being provided with carriers which are partially imbedded in the synthetic plastic of said saw blade, said fiber material being formed as a plurality of fabric-like mats which are arranged in said saw blade in at least one layer, said mats being formed as circular segments which are arranged in a rotation-symmetrical manner relative to an axis of said saw blade and have edge regions which overlap each other.
2. A saw, comprising a saw blade having an edge; and a cutting coating arranged on said edge of said saw blade and selected from the group consisting of a diamond-containing coating and a cubic crystalline boron nitride-containing coating, said cutting coating being subdivided into a plurality of individual cutting segment, said saw blade being composed of a synthetic plastic reinforced with a fiber material composed of a plurality of fibers selected from the group consisting of carbon fibers and graphite fibers with a volume fraction of 30-70%, said cutting segments being provided with carriers which are partially imbedded in the synthetic plastic of said saw blade, said carriers being provided with substantially dove-tailed shaped recesses.
3. A saw, comprising a saw blade having an edge; and a cutting coating arranged on said edge of said saw blade and selected from the group consisting of a diamond-containing coating and a cubic crystalline boron nitride-containing coating, said cutting coating being subdivided into a plurality of individual cutting segment, said saw blade being composed of a synthetic plastic reinforced with a fiber material composed of a plurality of fibers selected from the group consisting of carbon fibers and graphite fibers with a volume fraction of 30-70%, said cutting segments being provided with carriers which are partially imbedded in the synthetic plastic of said saw blade; and a plurality of bushes imbedded in said saw blade and provided for said carriers, said carriers of said cutting segments being U-shaped and having legs which are screwed to said saw blade.
4. A saw, comprising a saw blade having an edge; and a cutting coating arranged on said edge of said saw blade and selected from the group consisting of a diamond-containing coating and a cubic crystalline boron nitride-containing coating, said cutting coating being subdivided into a plurality of individual cutting segment, said saw blade being composed of a synthetic plastic reinforced with a fiber material composed of a plurality of fibers selected from the group consisting of carbon fibers and graphite fibers with a volume fraction of 30-70%, said cutting segments being provided with carriers which are partially imbedded in the synthetic plastic of said saw blade; and a plurality of bushes imbedded in said saw blade and provided for said carriers, said carriers of said cutting segments being U-shaped and having legs which are riveted to said saw blade.
5. A saw, comprising a saw blade having an edge; and a cutting coating arranged on said edge of said saw blade and selected from the group consisting of a diamond-containing coating and a cubic crystalline boron nitride-containing coating, said cutting coating being subdivided into a plurality of individual cutting segment, said saw blade being composed of a synthetic plastic reinforced with a fiber material composed of a plurality of fibers selected from the group consisting of carbon fibers and graphite fibers with a volume fraction of 30-70%, said cutting segments being provided with carriers which are partially imbedded in the synthetic plastic of said saw blade, each of said carriers having a T-shaped cross-section and is provided with a central web which is imbedded in the synthetic plastic of said saw blade.
6. A saw as defined in claim 5, wherein said carriers have a transverse beam which is wider than the thickness of said saw blade.
7. A saw as defined in claim 5, wherein said central webs of said T-shaped carriers are provided with openings.
8. A saw as defined in claim 5, wherein said central webs of said T-shaped carriers are provided with ribs.
9. A saw as defined in claim 5, wherein said central webs of said T-shaped carriers are provided with grains.
10. A saw as defined in claim 5, wherein said central web of said carriers is ring-shaped.
11. A saw as defined in claim 2, wherein said carriers together form a single one-piece ring-shaped carrier which carries all said cutting segments of said cutting coating and is partially imbedded in the synthetic plastic of said saw blade.
