Manufacturing profile arm for switching cabinet involves fixing toothed parts formed in one lateral region of sheet strip into corresponding apertures formed in other lateral region or other region

摘要

The method involves cutting a strip of sheet material to a length corresponding approximately to the length of the fabricated frame arm and connecting at least one longitudinal lateral region (10) of the strip rigidly to the other lateral region (15) or to another region of the strip. Tooth parts (14) are produced in one lateral region and bent into and fixed in corresponding apertures (16) formed in the other lateral region of other region of the strip.
