FIELD: technological processes; engines and pumps. ^ SUBSTANCE: drive includes an engine, reduction gear, roll rotation sprockets skirted by roller chain, power train and idler sprocket, with power train positioned at the inlet side of machine. Four rolls of each mill lie in the same diametric plane and form two strips simultaneously. To rotate the rolls the chain grips opposite left or right sides of vertically adjoining sprockets of one mill in sequence, and passes from lower sprocket of the previous mill to upper sprocket of the next mill along the rolling course. ^ EFFECT: reduced production cost due to simpler and cheaper machine drive. ^ 3 cl, 1 dwg, 1 ex |
