Abstract (en)
[origin: EP2105291A2] The device has a scale (54) e.g. incremental scale and absolute scale, arranged on one of upper and/or lower punches (18, 20), where the scale runs parallel to a vertical movement direction of the respective punches. A reading device (56) is associated to the scale and is synchronously rotated with a rotor (12). The reading device is provided for measuring a vertical position of the respective punches by optically, magnetically, capacitively and/or inductively reading out the scale. The reading device is arranged on upper and lower receptacles (22, 24) of the respective punches. An independent claim is also included for a method for measuring a vertical position of upper and lower punches.
