The casemaker (flexo folder gluer) produces in a single pass regular, cut, cordoned, flexo-sheets, folded and glued, are the American boxes, finished boxes. The main elements of the casemaker are: Feeder: which stacks and squares the input card before introducing it into the machine at the required speed. Several flexographic printing units, slotter unit, for cutting and engraving cardboard sheets, allowing the formation of panels, flaps and the glue tongue of the box
An optional rotary die cutting unit that allows you to create any required complex die-cut shape
Folder gluer section: to apply the adhesive to the glue tab and fold a part of the board along a creasing line
Counter and ejector: stack the cases in the required quantities based on the thickness of the material. The counter ejector offers a bundle of complete crates ready to be tied and palletized manually or with an automatic palletizer.
In a modern casemaker line, each print unit includes:
Anilox roller: a highly engineered and / or ceramic metal cylinder, which is laser engraved with tiny cells of a given angle, line screen and volume to provide the required fineness of the print
Chamber Blades: a device that supplies a measured quantity of ink to the anilox roll cells
Clichè door cylinder: on which the printing clichés are mounted
Ink system: ink collection tank, ink pump, as well as other elements to ensure ink and viscosity maintenance
Among the printing units, it is possible to install the dryers so that subsequent colors can be applied to the substrate without melting with those previously printed. These dryers can use hot air, infrared or ultraviolet light, depending on the application.
During the printing process, the ink arrives at the doctor blade chamber, transferring it through the two blades inside the anilox cylinder, screened. As the anilox turns, it comes into contact with the clichés, transferring the ink. The cliché rotates to transfer the image onto the substrate. With the current market needs, the graphics have reached a lata quality on packaging, with increasingly sophisticated packaging forms, requiring high graphics, with multi-colored prints, on glossy cartons, for the production of exhibitors and packaging ready to be put on the shelves.
