JumboGlass is a new single-roller machine, suitable to the enamelling and design printing of glass sheets "Jumbo size" by means of an engraved cylinder. The new solution works with an engraved roller in reverse mode, with maximum working width 3300 mm and thickness of the sheets from 2 up to 19 mm; the coating quantity can be setted from 50 g/ m² up to 350 g/m² (from 30 up to 220 micron) in only one pass.
As all Rollmac branded machine, the rollercoater has a special antidripping device that guarantees uniform and precise coverage of the surface, avoiding the accumulation of paint in the leading and trailing edges of the sheets.
Another very interesting feature is the possibility to be placed in line with the GLASSLINE 3400 perimeter edges printer, with space optimization that allows the customer to have two machines use the same oven.
In addition, the machine offers some innovative optionals:
- the tilting and ergonomic feeding belt, to be positioned in the front part of the machine, which allows the easy replacement of the rubberized sleeve;
- the automatic washing system of the engraved sleeve to facilitate cleaning operations at the end of processing and color change;
- the rollers storage system, located in the upper part of the machine and independent from its main body, which solves the logistical problem of depositing unused sleeves and that relating to greater operator safety as it facilitates the insertion of the sleeves in the working position.
Below, the technical characteristics of the new JUMBOGLASS 3400:
- main conveyor belt of special rubber with high resistance to oils and solvents. The conveyoir belt can be quickly and easily replaced from the front side of the machine (feeding side),
- roller holder with one position, with quick change system for the engraved roller,
- centesimal variation of the working thickness with digital indicator, indipendent LH/RH side or in tandem; this setting is achieved by the vertical positioning of the engraved roller. The positioning is by two jacks with synchronization shaft driven by a gearmotor,
- automatic positioning of the engraved roller (edge antidripping device) in order to avoid excess delivery of paint at the glass sheet entry edge.
WORKING POSSIBILITIES
- REVERSE engraved cylinder: coating, enamelling and painting.
- SYNCHRO engraved cylinder: design effects.
