FIELD: manufacture of powdered belts for surfacing wide surfaces of articles. SUBSTANCE: method comprises steps of flattening tubular blank with lock-type joint at deforming it in closed roll grooved passes at percentage reduction 40-50% for each pass; determining diameter of tubular blank according to relation P/P/π, where P - length of cross section perimeter of metallic envelope of ready surfacing belt. EFFECT: enhanced quality and operational characteristics of powdered surfacing single-joint belt due to elimination of powder spilling from it and preventing moisture penetration to powder-filler. 2 dwg
