FIELD: metallurgy.
SUBSTANCE: method includes blank heating and its edge cutting machining. Before edge cutting machining blank is subject to tension by effort up to 0.6 of paper-based laminate strength limit. Blank heating is implemented up to the temperature lower the temperature of vitrifying of binding agent - 90°C…100°C. Blank is subject to tension during 20 minutes.
EFFECT: enhancement of manufacturing capabilities of blanks treatment made of paper-based laminate.
