Abstract

A method for the manufacture of rectangular ducts, preferably designed for ventilation installations, characterized in that two or more metal sheets are driven forward from supply rolls arranged parallel to a metalworking machine, where the strips metallic elements are attached to a sheet of a single material having a width corresponding to the intended length of the conduit, and that the sheet of material is then cut into lengths corresponding to the intended circumference of the conduit, then being curved and assembled said lengths in form known per se to form closed conduits.
