member and being arranged to receive the signals from the signalling device at least when the bearing member is in a predetermined position, wherein the at least one exchangeable cylinder has an axis, and the bearing member is rotatable about an axis that extends one of: in parallel with, and coincides with the axis of said one cylinder containing said signalling device. ### Claim 2 (depends on 1) The printing press according to claim 1, wherein the bearing member is rotatable about an axis that is defined by the associated bearing. ### Claim 3 (depends on 2) The printing press according to claim 2, wherein the bearing member carries at least one said sensor head that is adapted to be, by rotating the bearing member, tilted into an active position in which the bearing member receives signals from the signalling device of said one cylinder. ### Claim 4 (depends on 1) The printing press according to claim 1, wherein the first exchangeable cylinder that is supported in the bearing associated with the bearing member includes an RFID chip as the signalling device, and the bearing member includes a corresponding RFID reader as one said sensor head. ### Claim 5 (depends on 1) The printing press according to claim 1, wherein: the signalling device includes a position mark, one said associated sensor head includes a position sensor, and one of: the movable bearing member and an associated component part has mounted thereon a position measuring device for measuring a position of the bearing member relative to said component part. ### Claim 6 (depends on 5) The printing press according to claim 5, wherein: the first exchangeable cylinder has an axis, the bearing has a bearing arm carrying the bearing member, said bearing arm being slideable along an axis in parallel with the axis of said first exchangeable cylinder, and the position measuring device is arranged for measuring an axial position of the bearing member relative to the component part. ### Claim 7 (depends on 6) The printing press according to claim 6, wherein the bearing arm is tiltable about an axis that extends in parallel with the axis of the first exchangeable cylinder. ### Claim 8 (depends on 5) The printing press according to claim 5, wherein the position measuring device comprises at least one magnet and a corresponding magnet sensor. ### Claim 9 A printing press comprising: at least one exchangeable cylinder rotatably supported in a machine frame, a movable bearing member forming part of a bearing for supporting a first exchangeable cylinder of the at least one exchangeable cylinder, a signalling device mounted on one cylinder of said at least one exchangeable cylinder of the printing press, and at least one sensor head adapted to receive signals from the signalling device, the at least one sensor head being mounted on the movable bearing member and being arranged to receive the signals from the signalling device at least when the bearing member is in a predetermined position, wherein the bearing member carries two sensor heads which can alternatingly be tilted into an active position. ### Claim 10 (depends on 9) The printing press according to claim 9, wherein the first exchangeable cylinder that is supported in the bearing associated with the bearing member includes an RFID chip as the signalling device, and the bearing member includes a corresponding RFID reader as one said sensor head. ### Claim 11 (depends on 9) The printing press according to claim 9, wherein: the signalling device includes a position mark, one said associated sensor head includes a position sensor, and one of: the movable bearing member and an associated component part has mounted thereon a position measuring device for measuring a position of the bearing member relative to said component part. ### Claim 12 (depends on 11) The printing press according to claim 11 wherein: the first exchangeable cylinder has an axis, the bearing has a bearing arm carrying the bearing member, said bearing arm being slideable along an axis in parallel with the axis of said first exchangeable cylinder, and the position measuring device is arranged for measuring an axial position of the bearing member relative to the component part. ### Claim 13 (depends on 12) The printing press according to claim 12, wherein the bearing arm is tiltable about an axis that extends in parallel with the axis of the first exchangeable cylinder. ### Claim 14 (depends on 11) The printing press according to claim 11, wherein the position measuring device comprises at least one magnet and a corresponding magnet sensor. ### Claim 15 (depends on 9) The printing press according to claim 9, wherein the bearing member carries at least one said sensor head that is adapted to be, by rotating the bearing member, tilted into an active position in which the bearing member receives signals from the signalling device of said one cylinder. ### Claim 16 A printing press comprising: at least one
