ABSTRACT:
A conically shaped metal screen body, especially for household juice centrifugals, is made of a plain circular-sector screen foil member which is first produced. The sector member is then brought into the three-dimensional closed conical shape by forming a longitudinal seam along the radial edges. The upper end of the closed conical shape is then provided with a fitting flange for bracing and for deflecting the juice. The lower end is also provided with a fitting flange for connecting the screen body to the driving shaft and/or for securing a rasping or grating disk. The upper and lower fitting flanges of the screen body are made by non-cutting shaping from corresponding rim allowances at both radial ends of the screen foil member. Thus, the finished screen body is a single piece, integral structure.
