Method for position monitoring, in particular without position sensors, and assessment of the correct position of a slide, in particular work slide, of a wedge drive tool (2) in a press (11) when the slide bed of the wedge drive tool (2) is actuated from an end position (X) back to its starting position (X) by means of a Spring, preferably a gas pressure spring (10) arranged in the wedge drive tool (2) when the press (11) is opened from a lower to an upper press position, with an indirect and indirect position detection of the slide being provided, in which at least the restoring force of the spring (10) is recorded and evaluated, with the following steps: a) detecting the restoring force F (t) of the spring or gas pressure spring (10) at at least one time t, which is on or after the start of the respective opening process of the press (11), at which the slide is actuated by the spring or gas pressure spring along the distance x from its E b) Determine whether the restoring force F (t) is greater, equal or less than a predetermined target restoring force F (x), which is the Restoring force at location x and c) determining the respective state value at time t which represents a permissible or impermissible actual position P of the wedge drive tool at position x between the possible positions X and X (starting position and end position), with d) generating an action for stopping the Press, if the value of Pals is determined as an inadmissible state value.
