Abstract
Metal sheets, and in particular, metal sheets for roofing of the kind having upstanding flat edges ending with beads, are bent by rolling the flat edges such that they become gradually thinner towards the beads. The sheets will also be bent if the beads are not rolled. Metal sheets having upstanding sides, and ends bent towards or away from the upstanding sides, are also bent by rolling the upstanding sides gradually thinner towards or away from the bent ends for forming beams for automotive components as well as other products.
