L    loader contains all the devices requried to automatially load the containers.

       Loading screws cyingdrical components of a helical shape . The synchronized movement of these elements separates the containers of the stack entering on the loader and loads them one in phase with revolver movement.

 

M    machine cycle this ,eans the rotain the machine components must accomplish to produce a container. A spining shaft that accomplishes one single revolution during the production of a container is normally taken as a reference and rotation is measyred in degrees, to obtain a 360 cycle . The time taken to accomplish a cycle is called cycle time and varies as the machine speed changes.

       Magnetothermic protector switch eletromechanically activated device installed protect the electric circuits, motors, etc.

       Mandrel fixturing element fixed to the revolver , on which the container is loaded .

       Mixer accessory that mixes the ink the ink fountain.

        

N    no cup no print container detecting function: if the container fails to be loaded , a device moves the printing frame away when  the empty mandrel nears the printing station and then sets it back in the position when the next containe arrives.

       Nozzle shaped duct to supply conpresses air.

 

O   optic centering device accessory used to assemble and phase the various printing plates.

      Oscillating roller this is part of the colorhead and spreads (distributes) the ink while conveying it towards the next roller. The oscillating roller accomplish a crosswise movement while they turn, controlled by other mechanisms or generated automatically.

      Ozone a gaseous element with a high oxidizing power, harmful to the health of human beings. It is caused by the ionization of the air following electrical discharges (electronic treatment ) and ultraviolet rays (when the ink is dried ).

P     plc electronic device that monitors the machine functions according to a program compiled in the OMSO plant.

        Penumatic lubricator device used to mix a quantity of finely dosed oil with the compressed air .

        Pressure switch electropneumatic device that monitor the pressure of the air in the system on board the machine: if the pressyre drops beyond the preset limit, the machine will stop in the fault condition since it will be impossible to use the air-operated devices.

        Printing frame part of the machine that supports the colorheads and mechanisms that drive them, plus other parts directly involved in the printing process(central drum).

        Printing length represents the length of the printable image.

        Printing plate plate of a previously established and calibrated thickness made of different materials, depending on requirements or preference (Zinc, N ylon, Nylon-print, M agnesium). After the colours have been selected, one of the monochromatic images of which the print consists applied to the printing plate by the photoengraving process.
