"Press that accelerates the idle travel to be driven through "

The invention relates to mechanical ones driven by a single electric motor via an intermediate gear; 'Presses, in which the idle travel with respect to the working path y sawn be run through accelerated and their drive members ^always; i run in the same direction of rotation. These can be me-Z ₁ mechanically driven presses of all kinds, such as crank, eccentric, cam-controlled and toggle-lever drawing presses of single or double-acting design,

Ea is already known to pass through the idle travel faster than the commute to leave .- run at a press up and abbewegtem ram eg άβΆ high gear at about twice the speed than the Fiedergang where pulling ER \ '' · ■■ · follows.

The invention achieves the advantage that, despite the change in the speeds within one engine, the usual drive slectromotors of the same power can be used as they are otherwise customary when using a flywheel. I'm -and the same engine and flywheel are running, also after. The press ₉ is switched off when the ram movement is stopped. »Despite the change in ram speeds, the speed of the drive motor and the centrifugal masses remain the same throughout the entire working cycle:» The work capacity stored in the centrifugal masses _{: becomes after:} Switching from the higher! lower working speed fully used to carry out the work process.
