Patent ID: 7294300

Claim:
A method of producing a grinding plate which has a plate member having an upper plate surface with an upper plate edge, a lower plate surface with a lower plate edge for placement of a grinding means and extending at least partially beyond said upper plate edge, and a side surface extending from said upper plate edge to said lower plate edge and having in a projecting region of said lower plate edge a pagoda-shaped concave contour, the method comprising the steps of: selecting a material of a grinding plate, a material thickness, a plate thickness of the plate body, a round bar diameter, a penetration depth of the round bar into the plate body and/or a distance of the separating cut from the outer edge of the round bar in correspondence with a desired course of the pagoda-shaped contour; punching out the plate body with the upper surface, the lower surface and the side surface from an elastic material in a desired shape; placing a round bar on the upper plate surface along the upper plate edge of the plate body with a parallel distance from it; pressing the round bar into the plate body so that an elastic material of the plate body is squeezed outwardly under the round bar; separating the squeezed out material along an outer edge of the round bar with a separating cut extending perpendicular to the plate surfaces at a predetermined distance from an outer edge of the round bar and; removing the round bar from the upper plate surface; and further comprising with a cellular rubber as a material of the grinding plate, and a plate thickness of approximately 8 mm, selecting a round bar diameter of approximately 10 mm, a penetration depth of the round bar into the plate body of approximately 5 mm, and a distance of a separating line from the outer edge of the round bar of approximately 2 mm.
