Patent ID: 7757606

Claim:
A press, comprising: a rotatable component, wherein the rotatable component is a drive shaft of a press cylinder of the press; and a position registering device, wherein the position registering device registers an angular position of the component and wherein the position registering device is a magnetic rotary encoder including an index ring that is fixed to the drive shaft of the press cylinder and a sensing head disposed on a stationary bearing element of the drive shaft; wherein the index ring is fixed to the drive shaft of the press cylinder by a clamping ring connection including a first clamping ring element seated on the drive shaft and a second clamping ring element disposed within the first clamping ring element, wherein the index ring is connected to the first clamping ring element and wherein the first clamping ring element is fixed to the drive shaft by the second clamping ring element pressing the first clamping ring element against the drive shaft; and further wherein the sensing head is disposed on the stationary bearing element by a carrier element attached to the stationary bearing element, wherein the sensing head is attached to an axially extending section of the carrier element.
