Standard technical characteristics

  • 6-station vertical rotating turret with indexing movement;
  • hinged roller-holding heads for easy opening in order to facilitate plate changing and plate and roller cleaning;
  • the containers are kept on solid mandrels by means of air vacuum;
  • rollers on ink fountain controlled by a 3-phase A.C. motor, with frequency converter, in order to ensure adjustment of a precise quantity of ink;
  • ductor roller for accurate ink-feed setting, controlled by an electric sequencer adjustable through inverter and managed by machine PLC;
  • all the gears have inclined teeth to ensure a positive control and avoid shadows on the decoration;
  • electropneumatic device for printing head shifting to prevent printing on the mandrel when a container does not come into printing position (“no container – no printing” device);
  • fine adjustment of printing pressure by moving the complete printing head by manual control according to container;
  • fine adjustment with manual control for the inclination of the printing head according to the container taper;
  • one colour unit is provided with an oversize diameter form roller (1:1 with plate-roller diameter) to prevent ghosting;
  • in order to allow a suitable inspection on printing head suitable stars is provided;
  • electronic synchronism (electric shaft) between brushless motor for indexing turret driving and brushless  motor for Printing head control;
  • rapid plate fixing on the rollers through a series of holes on the plate itself and fixing pins on the roller. To this purpose one manual punching tool is supplied with the machine to perforate correctly the plate edge. In this way it is possible to get an easy and quick change-over of the plate and its fine registration;
  • central printing roller with ceramic coating;
  • control of all machine and accessory functions by a PLC with digital Bus Field system;
  • independent speed variator with 3-phase motor and electronic control of number of revolutions of mandrels in stations of cleaning, flame treatment and UV curing through inverter and synced with the speed of the machine;
  • automatic unloading device to release the pails with the mouth facing upwards;
  • flame pre-treatment with electronic flame detection;
  • on-mandrel drying through UV lamp with electronic control.

Optional Devices

  • dust cleaner and static electricity remover;
  • automatic feeding system of pails (denester);
  • automatic horizontal or vertical restacking unit;

  • connection to lacquering machine;
  • UV drying tunnel for elliptical / rectangular containers;
