Abstract

A method for producing at least one cutting strand segment of a cutting strand comprises punching at least one cutting strand segment out of a band material. The at least one cutting strand segment includes at least one cutting element and at least one cutter carrier element having at least one connecting element.

First claim

The invention claimed is:

1. A method for producing at least one cutting strand segment of a cutting strand, the cutting strand segment including at least one cutting element and at least one cutter carrier element having at least one connecting element, the method comprising:
punching the at least one cutting strand segment out of a band material; and
welding a cutting edge reinforcing element to the at least one cutting element of the punched out at least one cutting strand segment,
wherein the band material is bimetal.

2. The method as claimed in claim 1 , further comprising:
subjecting the at least one cutting strand segment to an embossing operation at least in a subregion of the at least one cutting element.

3. The method as claimed in claim 1 , further comprising:
feeding the at least one cutting strand segment to a finishing device.

4. The method as claimed in claim 3 , further comprising:
in the finishing device, applying a coating to the at least one cutting strand segment at least onto the cutting edge reinforcing element of the at least one cutting strand segment.

5. The method as claimed in claim 4 , further comprising:
in the finishing device, furnishing particles to the at least one cutting strand segment at least onto the cutting edge reinforcing element of the at least one cutting strand segment to which the coating is applied.

6. The method as claimed in claim 1 , further comprising:
embossing a transverse securing element onto the at least one cutter carrier element.

7. The method as claimed in claim 1 , wherein the welding forms a weld seam between the at least one cutting element and the cutting edge reinforcing element, and a maximum spacing between the weld seam and a cutting edge of the cutting edge reinforcing element, measured perpendicularly to a cutting direction of the at least one cutting element, is less than 1 mm.

8. The method as claimed in claim 6 , wherein the welding forms a weld seam between the at least one cutting element and the cutting edge reinforcing element, and a first maximum spacing between the weld seam and a cutting edge of the cutting edge reinforcing element, measured perpendicular to a cutting direction of the at least one cutting element, is less than 0.4 mm and a second maximum spacing between the weld seam and a nearest embossed contour, measured perpendicular to the cutting direction, is less than 0.8 mm.

9. The method as claimed in claim 8 , wherein a maximum extent of the weld seam, measured perpendicular to the cutting direction, is less than 800 μm.
