A method for producing a primary material for a cutting tool, for example a primary material for a saw blade or a saw band, in which a band-shaped carrier of a metal carrier material and a wire of high-speed steel are continuously brought together along a lateral edge of the band-shaped carrier and transported into a welding device and the band-shaped carrier is welded to the wire along the lateral edge of the carrier to produce a bimetal band. The band-shaped carrier and the edge wire are welded to one another by at least a first welding device, which is arranged on one side of the band-shaped carrier, and at least a second welding device, which is arranged on the opposite side of the band-shaped carrier.

The present invention relates to an electrodeposited diamond wire saw using patterned non-conductive materials in which non-conductive materials are pre-patterned along the outer circumference of a wire on which diamond grit should not be rubbed, before the diamond grit is upset, in order to efficiently improve the manufacturing process, and to a method for manufacturing same. According to one preferred embodiment of the invention, the method for manufacturing an electrodeposited diamond wire saw includes: printing a masking solution on the outer circumference of a wire in a plurality of directions when the wire is inserted for patterning; and upsetting diamond grit on the remaining regions of the outer circumference of the wire, with the exception of the patterned region.

A saw wire to cut hard and brittle materials is disclosed that comprises a steel wire that is provided with bends with segments in between. The average degree of bending of the bends is between 0.5% and 5%. Such a saw wire has a higher breaking load compared to saw wires having a conventional, higher average degree of bending. A method to measure the curvature is described as well as a process to make the inventive saw wire. The invention is applicable to any shaped saw wire for example a single crimped saw wire, a saw wire with at least two crimps in different planes, a saw wire with crimps rotating in a plane.

The present disclosure relates to a method (100) for production of a chainsaw guide bar (5). The method comprises the steps of providing (120) an elongated core plate (5) extending along a plane, and, in said plane has a length (Lc) in the longitudinal direction (D), and a width (Wc) perpendicular to the longitudinal direction (D), comprising a pair of opposite long side edges (33) and at least one detachable element (31) that extends along at least one of the long side edges of the core plate. Arranging (140) a side plate (23a, 23b) on each side of the core plate (25), thereby forming a sandwiched structure and joining (160) of the plates (23a, 23b, 25) for formation of an elongated guide bar (5), wherein the at least one detachable element (31) remains attached to the core plate (25). The disclosure also relates to a guide bar (5) for a chainsaw (1). The guide bar (5) comprises a laminated structure of at least three layers comprising a first side plate (23a), a second side plate (23b), and a core plate (25) disposed between said first side plate (23a) and said second side plate (23b), wherein the core plate (25) is provided with at least one detachable element (31). The disclosure also relates to an alternative method (200) of production of a chainsaw guide bar (5).

Methods and apparatus for making and using tools, for example concrete cutting blades. The tool includes a first layer and a second layer that are oppositely disposed. The first and second layers include working surfaces that support at least one working element when the working element is applied to a work piece. Additionally, an intermediate structure is included between the first and second layers. The intermediate structure can include a plurality of components extending in the area between the structural surfaces and the working surfaces.
