Abstract: A grinding plate for an electric hand grinder 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 the upper plate edge, and a side surface extending from the upper plate edge to the lower plate edge, and having a pagoda-shaped contour in a projecting region of the lower plate edge and the grinding plate is produced by a method including 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; and r

Abstract: The manufacturing method of the invention manufactures a fuel filler pipe (branching pipe), where a breather pipe is branched off from a filler pipe main body. The manufacturing method extrudes a first extruded tubular member and a second extruded tubular member, conveys molds arranged on both sides of the first extruded tubular member and the second extruded tubular member, and forms the first extruded tubular member and the second extruded tubular member corresponding to molding surfaces of the molds, so as to mold the filler pipe main body and the breather pipe. The manufacturing method then thermally welds part of the second extruded tubular member with an outer wall of the first extruded tubular member and closes an opening end of the breather pipe to form a welding joint portion. A connection hole for connecting the conduit of the filler pipe main body with the conduit of the breather pipe is formed in the welding joint portion with a tool inserted through an opening of the filler pipe main body.
