Abstract
The press is of the type including a pair of tool-holders mounted in a frame and carrying cooperating tools (die and punch). At least one of the tool-holders is motor-driven and is movable towards the other tool-holder. According to the invention, the press includes first drive means arranged to make one of the tool-holders travel a fairly long distance towards the other tool and second drive means, distinct from the first, for making this same tool-holder or the other tool-holder perform a subsequent, fairly-short working stroke to bend the sheet metal and to effect any coining of the bend. Preferably both of the tool-holders are movable, the second drive means being arranged to make the respective tool-holder complete a fairly short bending stroke, and the press includes third drive means, distinct from the first and second, arranged to make the same tool-holder and the other tool-holder complete a virtual stroke for coining the bend.
