The corrugator is a machine that couples the various papers and cuts the tape in order to achieve the desired format to obtain corrugated cardboard sheets.
The latest generation line installed in Ghelfi Ondulati is designed for industry 4.0.
The sheets of corrugated cardboard before being processed in the box factory are stored in the semi-finished warehouse; it is here that the cardboard cools and “ripens”, i.e the process of evaporation of the contained water and of the polymerization of any resins is completed.
The system works as an intermediate buffer between the box factory and the corrugator, and in a totally automatic way is able to manage the unloading of the cardboard from the corrugator and then make it available for processing when required.
Flexo printers are normally used in “post-print”: this is a type of print that uses water-based inks and stamps engraved on very soft polymers (clichés). Each cliché transfers a certain color to the cardboard sheet. The plate is held inked by a rolled roller (anilox) and transfers its image to the cardboard sheet for “stamping”. For a good print result, the anilox line should be coordinated with the type of media on which the printing (paper and wave) and with the image to be represented takes place.

Flexographic printing machine with 6 printing groups. Over time our Masterflex has been retrofitted with all available options, to maintain the performance, but above all the possibility of offering a product of the highest quality to the customer.
The die is the matrix on which blades and cords are mounted to reproduce the packaging starting from the printed sheet. There are rotary and flat die-cutting machines. The former are faster and more productive, the latter are more precise in terms of size. The cleaning of the punching waste is entrusted to the gumming in the rotary die-cutting and to a special tool in the flat die-cutting.
Flat die-cutting machine of the latest generation, equipped with the Power Register system for automatic rewinding during the punching phase.
It produces the American boxes starting from an unprinted cardboard sheet in a single machine passage: it is made up of several simplified printing units, a die-cutting unit, a slotter and a folder.
