Abstract: The present invention discloses a printing unit with an automated sleeve change process. A sleeve can be prepared for the next printing job while the current job is running, thereby reducing the changeover time. Also, the printing unit can handle printing sleeves of very different sizes without any special additional adjustments to be made. The printing unit translates the printing roller and the inking roller on a horizontal line to engage and dis-engage the printing roller. The invention is convenient for large printing sleeves because the sleeve can be slipped over a shaft that remains in the unit. The setup results in a very rigid system, which guarantees an excellent printing quality.

Abstract: System for measuring motor bearings consumption of railway vehicles, comprising: a phonic wheel, arranged to be fixed to a shaft of a rotor, having a profile including an alternation of teeth and holes; a sensor, arranged to measure a punctual air-gap between the teeth of the phonic wheel and said sensor during rotation of the shaft, said sensor generating a basic sinusoidal signal function of said profile, wherein the basic sinusoidal signal is superimposed to a modulating wave, representative of a radial motion of the shaft, the basic signal and the modulating wave forming a complete signal; characterized in that the sensor further comprises: a control unit arranged to measure a maximum and a minimum amplitude value of the complete signal, said maximum and minimum amplitude values representing the maximum and minimum air-gap between the phonic wheel and the sensor, and for calculating an air-gap swing value; memory means arranged to store said air-gap swing value; wherein said sensor is arranged to send to
