Formed or domed cutting teeth formed by improved double etching processes

摘要

A device and method for manufacture thereof having a one or more cantilevered cutting teeth (10) integrally formed in raised configuration on a flat base (12) for cutting food items moved along said base (12). The free end portion is formed by upper and lower etched out portions of the upper end of said cutting teeth to form a cutting edge (22). The upper surface of the upper cut-out portion (26) of the teeth (10) is situation at a position out contact with food items being cut. A substantially portion of the teeth (10) is coated with a low friction material, except for the cutting edge (22). In a second embodiment one or more domed cutting elements (2b) are cut out of base sheet (8b) and may include a leading V-shaped cutting edge (10b).
