Abstract
Methods and apparatus for making and using tools, for example concrete cutting blades. The tool includes a first layer and 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.
Claims19
A tool comprising:
- a first and second oppositely disposed layers, wherein each of the first and second layers includes structural surfaces for being supported on a drive assembly, and wherein each of the first and second layers includes working surfaces for supporting at least one working element when the at least one working element is applied to a work piece;
- an intermediate structure between the first and second layers, wherein the intermediate structure includes a plurality of components extending in an area between the structural surfaces and the respective working surfaces, and wherein the intermediate structure is less than co-extensive with the first and second oppositely disposed layers;
- and
- a continuous weld ring at least partially interposed between a perimeter of the first and second layers.
A tool having a circular shape comprising
- a lamination of at least two layers including a first layer and a second layer and an adhesive layer;
- a medial section and an additional adhesive layer, wherein the adhesive layer and the additional adhesive layer are located on opposite sides of the medial section and the first layer and the second layer are in registration with one of the respective adhesive layer and additional adhesive layer;
- a continuous weld ring at least partially interposed between a perimeter of the first and second layers;
- and
- a plurality of arc-shaped cutting segments having an inner arc shape and an outer arc shape, wherein the arc-shaped cutting segments are coupled to the continuous weld ring.
