Abstract: An improved press line is described which comprises at least one mechanical press with at least one electric drive motor (20), a ram (23), a mechanical means (27, 25) for operating said press, and one other device or auxiliary production device, which press is arranged so that the speed (W) of the at least one said drive motor may be varied during at least one pressing or non-pressing part of a press cycle. Improved operating characteristics and optimised energy use and cycle times are obtained by controlling the speed of said motor and synchronizing a movement of said press to a movement or position of at least other device, loader or other press. A system comprising such a press is described, and a computer program for controlling the press line.

Abstract: A method for operating a mechanical press including an electric drive motor, a drive control for controlling the motor, a ram, a flywheel, a clutch and a member for translating rotational motion of the flywheel in a first rotation direction into a linear motion of the ram arranged to be lowered and raised along a linear path for operating the press to carry out a press production cycle. The press cycle includes a pressing part and one or more non-pressing parts. The press includes a second drive motor or actuator arranged connected to the ram and by providing a control output to the drive control, the speed of the second drive motor is made variable during at least one part of the press production cycle. The press may be reversed between production cycles. A press and system including such a press.
