FIELD: machine engineering. SUBSTANCE: method comprises steps of feeding web between rotating cutters; setting constant value of linear velocity of cutters in synchronization zone before cutting, at time moment of cutting and after cutting and setting variable linear velocity of cutters in zone for controlling velocity; gradually changing velocity of cutters in controlled zone according to polynomial function Fn(t) = a0+a1t1+a2t2+...+antn where a0,, a1,... an -coefficients of polynomial function, t - time period calculated beginning from time moment of cutter introducing to controlled zone, n - order of polynomial function. EFFECT: enhanced accuracy of cutting web, lowered wear of mechanism for rotating cutter shafts. 7 dwg, 1 ex
