FIELD: metallurgy.
SUBSTANCE: mill of suture guiding rollers contains installed with ability of rotation at least one roller for linear leveling of free edge of profiled surface of metallic strip lengthwise specified of melting line. Mill of welding chamber contains installed with ability of rotation at least one couple of clamping rollers, provided for combined direction of heated up to specified temperature of free edge into welding area by specified line of melting on surface metallic strip. Moving of free edge is implemented by specified straight path in essence by line of approximation to resulting welding connection between specified free edge and mentioned surface of metallic strip. Welding power is focused ensured by effect of its closeness to mentioned specified line of welding at mentioned surface.
EFFECT: inventions provide avoiding of problems of heating passing in strip, out for welding line during levelling of free end, providing effectiveness increase of manufacturing.
