摘要： A forming machine comprises a rotatingly drivable gripping device (1) for gripping a forming tool (2) and a material plate (3) to be formed, a movable lower slide (6), a first driving means (8) for moving the lower slide, a movable upper slide (10, 35) mounted on the lower slide, a second driving means (11, 34) for moving the upper slide and a holder (5) for a forming roller (4) supported on the upper slide (10, 35). A control unit (16) is provided for controlling the movement of the forming roller (4) by actuating both said driving means (8; 11,34) said control unit being connected to a detector (18,21) for determining the force exerted on the forming roller (4) and to a detector (17) for determining the position of the lower slide (6). A memory (25) is connected to the control unit for storing corresponding force/position values. The control unit (16) is adapted to control the movement of the forming roller (4) in dependence on the force/position values stored in the memory (25). The forming roller (4) is coupled to the second driving means (11, 34) through a spring means (13,38) with a given spring characteristic. Said detector (18, 21) for determining the force exerted on the forming roller consists of a position detector (18, 21) for determining the compression of the spring means (13, 38).
