Abstract
Improvements introduced in sheet metal bending machines, with an upper cylinder and two driven lower cylinders, characterized in that the supports of the lower cylinders are arranged movable independently of each other and inclined with respect to each other, the upper cylinder being also carried on supports move them, providing a limiting device for the passage preferably between the lower cylinders.
