Carbon fibre rollers for flexographic printing allow production efficiency, constant quality and the possibility of rapid processing changes in the sector, that are the most important features in the machinery sector for flexographic printing and rotogravure. There are various possibilities for the application of carbon rollers on these machines:

  • In both printing technologies, it’s possible to replace a good part of the idle rollers and to manage with rollers of composite carbon fibre material. Given their low inertia, they ensure a soft dragging without stress or scratches on the printed film, and therefore a final product of excellent quality.
  • With flexographic printing it’s possible to substitute printing and anilox steel cylinders with carbon portamaniche This can greatly increase the speed and printing requirements, especially with difficult stereotypes.

Rollers intended for digital printing have recently been introduced. Their small dimensions allow for the production of extremely reduced batches.

 

Clichè rollers and air mandrels

Around these, the printing process turns. A carbon fibre mandrel (also with the standard elastic form) represented a substantial innovation in comparison to the steel mandrel. Equal in stiffness, it has, in fact, a decidedly lower weight, allowing it to obtain a much higher frequency. Even better working is carbon spindle with high elastic modulus. In addition to reducing weight, it increases rigidity, as opposed to steel. Reglass builds portacliché cylinders and portamaniche spindles, with diameters up to 420mm and table lengths up to 6m.

They receive ink from the reservoir through the blade, transferring it to the stereotype in a uniform manner. Normally they are subjected to a complex exchange of stresses, triggered by the vibrations of the stereotype cylinder. Thanks to Reglass technology these are greatly reduced, thereby avoiding repercussions in the distribution of the ink, with the added advantage of lower wear and tear. Reglass produces anilox rollers which, together with clichè rollers, enable unsurpassed performance in flexographic printing.
