Abstract RU 2202463 C2

FIELD: manufacture of disc blanks for large- size abrasive discs. SUBSTANCE: method comprises steps of blanking polyhedral blanks of rolled sheets; packing and compacting them. AT blanking polyhedral blanks the whole surface of vulcanite sheet placed on multiple lower die formed by belt cutters is squeezed by means of rotating roller at reciprocation motion of lower die and roller. EFFECT: less loss of mass of rolled sheets, lowered stratification of blanks, decreased labor consumption. 3 dwg
