20130192441 | MACHINE BLADE FOR FOOD PROCESSING - The present invention relates to a blade for cutting machines and to a method for producing such a blade. The blade has a main body made of a first material and a cutting body made of a second material and having at least one cutting edge formed thereon. The second material has a higher hardness than the first material. The cutting body is joined along a joining line to the main body. According to the invention, the blade is produced by: a) providing a support made of a third material of high thermal conductivity; b) placing the main body on the support such that a base area of the main body and a surface of the support lie substantially parallel to each other and the joining line is adjacent the surface of the support; c) generating the cutting body by build-up welding of the second material onto the first material along the joining line, the support being arranged for mechanically supporting the second material used for build-up welding and d) sharpening the cutting body to form the at least one cutting edge | 08-01-2013 |
