FIELD: technological processes.
SUBSTANCE: beforehand mushroom-shaped flutes are formed with semicircular tops and inter-flute sections and intermediate flutes are formed with vertical lateral facets on the front end of strip with length that is equal to inter-cage distance of profile-bending machine in the cage, the top roller of which has separating flanges. Rollers are distanced after forming of mushroom-shaped flutes for free passage of corrugated strip, mushroom-shaped flutes are formed in cages of profile-bending machine and intermediate flutes with vertical lateral facets are finally formed in the last cage of profile-bending machine by means of free setting with smooth rollers.
EFFECT: quality is improved; technological resources of the process are expanded and production costs are reduced.
