Abstract: The present invention concerns a method and an arrangement for the verification of individually presented items of mail provided with individually unique machine-readable identification codes, where the identification code of a presented item of mail is read and the identification code that has been read is checked against machine-readable information about intended items of mail and their status, whereby the current item of mail is a) removed if the identification code is not present in the intended items of mail or if it is illegible, and b) the status of the current item of mail is checked against the machine-readable information about intended items of mail and their status in order to determine whether the current item of mail has previously been delivered. If the current item of mail has previously been delivered, the current item of mail is removed.

Abstract: A caseless rotor assembly is provided. The caseless rotor assembly includes a rotor shaft, a high pressure portion with a high pressure rotor blade, a low pressure portion with a low pressure rotor blade, and a common wall between the high pressure portion and the low pressure portion. The common wall extends radially from the rotor shaft. The common wall itself includes a shaft end oriented towards the rotor shaft and an outer end on the other side of the common wall, oriented radially outwards. Additionally, the common wall surrounds circularly the rotor shaft.

Abstract: The present invention relates to a control method and a control device during fabrication of a series of cards (2), preferably credit or ledger cards, in which series each card (2) has hobbed symbols (3) which represent individual information (4-6) about the card possessor or card holder, e.g. his or her name and card number. The hobbed symbols (3) on each card (2) in the series are read by a laser emitter/receiver (8) emitting laser light (10) towards the cards (2) and receiving laser light (12) from said cards. Information obtained during reading and representing the hobbed symbols (3) of the cards (2), is compared with predetermined information for controlling if said informations correspond. An error is indicated if said informations do not correspond.

Abstract: An apparatus for cleaning a folding roller (2) on a roll folding machine has a capsule with an aperture for insertion of the folding roller (2) and a nozzle which is connected to a high pressure source of a cleaning agent. The nozzle is directed for emitting a jet (32, 33) of the cleaning agent and movement means against the peripheral or circumferential surface of the folding roller (2). In such instance, a relative movement is created between the folding roller (2) and the jet (32, 33) so that the peripheral or circumferential surface will be exposed to the action of the jet 10 (31, 33). A method of cleaning a folding roller (2) in a roll folding machine comprises the steps that the folding roller (2) is passed into a capsule and that the peripheral or circumferential surface of the folding roller (2) is exposed to a jet (32, 33) of cleaning agent under pressure.

Abstract: In a process in roller folding a folding roller is moved against a workpiece. The urging force of the folding roller against the workpiece is resilient, and the folding roller moves in a path along the workpiece by means of a movement device provided with a control system. The urging force is sensed by a sensor, which is integral in or included in the movement device, and the output signal of the sensor is fed to the control system.

Abstract: A folding tool for automatic roll folding comprises a first member (2) which is fixed to a manipulator, and a second member (3), which is rotatably connected to the first member (2). The second member (3) includes a first folding roller (4). A spring is disposed to permit a relative movement between the first member (2) and the second member (3), under the action of a force, which is increased by the movement. A method of roller folding by means of a folding tool, which includes a first member (2) fixed to a manipulator, and a second member (3) which is pivotal relative to the first. The second member is provided with a folding roller and is actuated by a spring force, which is directed away from the first member.

Abstract: Method and apparatus for cleaning a rubber coated cylinder (10) mounted in an offset printing machine for transferring the print from a printing plate cylinder (11) to a paper web (12) running in contact with the rubber coated cylinder, while the offset printing machine is running. The surface of the rubber coated cylinder is brushed by means of a brush (16) which extends in parallel with the cylinder and has substantially the length thereof and which is engaged with the rubber coating and imparted an axially reciprocating movement for loosening the contaminants and distribution thereof over the surface of the cylinder. Washing liquid is sprayed onto the surface of the rubber coated cylinder from a ramp (14) mounted in parallel with the cylinder and having a number of spray nozzles distributed along the ramp for dissolving the contaminants. Washing liquid and contaminants are removed from the surface of the cylinder by means of the paper web running through the offset printing machine.
