FIELD: technological processes.
SUBSTANCE: method for thermoprofile production involves strip feed to profile bending mill, sequential transit-wise element overcast by profile-bending mill rollers, perforation of slit row with deflanging in apron form, in checkered order on profile wall. Before feeding to profile-bending mill strip is unrolled from roll and shifted to form compensation loop. After perforation of slit row the profile surface is evened in leveling unit with further profile cutting at given length. Transfer line of cold shaping for thermoprofile production includes profile-bending mill with instrumental adjustments, device for perforation of checkered pattern of slits deflanged in apron form in wall of continuously moving profile. Unrolling and receiving units are positioned in series before profile-bending mill, and after slit perforation device a cutter is positioned. Slit perforation device features leveling unit.
EFFECT: extended functional capacities.
