Abstract
A bead roller sheet metal working machine having a first drive shaft and a second drive shaft arranged in a plane common to both drive shafts, wherein both drive shafts at their respective inner ends are driven by means of a drive unit which by a first transmission drives the drive shafts to rotate in opposite rotational directions, and where the drive shafts at their respective outer ends are equipped with dies by way of which the sheet can be provided with beads when the sheet is forwarded between the dies along a plane substantially tangential and common to both dies, and where a greater part of mutually facing surfaces of two arms carrying the drive shafts are located at a greater distance from one another than a distance between the outermost ends of the drive shafts to allow a curved work piece access to the machine while working.
