FIELD: process engineering.
SUBSTANCE: invention relates to metal forming and can be used for making channeled sheets for light metal structures. This comprises two vertically-looped pull chains arranged at its edges, their hinges being composed of rollers designed to interact with top stationary idle counter rollers for edge contouring. Note here that channeling forming elements are arranged between top braches of the chain and composed of idle flutes made up of self-lubing antifriction metal-graphite composite.
EFFECT: lower metal input.
