Abstract
The section modulus of elasticity of the body portions of the scraper blades in a meat scraping machine decrease substantially uniformly outwardly along each blade. The blades have flat, transversely flexible scraping edges on the ends opposite a common series of circular hubs. Each hub is slightly rotated with respect to the adjacent hub to provide a series of spiraling blade-like edges for engaging and scraping accumulated residues from the sawed surface of a piece of meat. An adjustable doctor blade removes the residue from the scraper blades. The uniformly decreasing section modulus of elasticity of each blade encourages uniform flexing along the length of each blade to distribute stresses and fatigue uniformly throughout the blade material. The blades are pre-flexed on the hubs to reduce the effective diameter of the blade structure and to reduce the flexing of the blades when encountering the meat and the doctor blade.
