FIELD: plastic metal working. SUBSTANCE: press has two rollers having varying clamp width and rotated in opposite directions by two reduction driving mechanisms, each installed on separate shaft and designed for one of corresponding rollers. Driving mechanisms have reactive system of torque in the form of two pairs of levers. Each pair of levers is rigidly connected to corresponding driving mechanism. Each lever of one pair is connected with respective lever of the other pair for transmission of forces proportional to torque and acting mainly in direction square to location plane of rotation axes of rollers. EFFECT: higher efficiency. 4 cl, 4 dwg
