METHOD FOR SHAPING LATERAL WORKING SURFACE OF TEETH OF TOOTHED RIM Russian patent published in 2002 - IPC

FIELD: machine engineering, instrument making, possibly manufacture of toothed rims, mainly of plastics and composition materials. SUBSTANCE: method comprises steps of using П-shaped belt having on its inner surface variable-thickness portions whose outer surface is development of lateral working surface of teeth; bending said portions for forming by their outer surface desired contour of lateral working surface of teeth; then filling volume of teeth formed by means of belt with hardenable material.
