Abstract (en)
[origin: EP0774306A1] The drawing units comprise two alternatingly moved tension slides, which draw the workpiece continuously through a drawing ring in a holder in each drawing unit. At least one drawing ring holder (3,4) of a drawing unit (A,B) is provided with a measurement device (5,6) for permanent assessment of the drawing force. The drawing ring holder in each case, dependent upon the measurement value, is movable or clampable, with force or torque regulated, in the longitudinal direction (7,8) of the workpiece. The measurement device comprises a force measurement box arranged between the drawing ring holder and the drawing ring (1,2).
