FLEXO Magazine : August 2011
74 FLEXO august 2011 www.flexography.org Grids can be moved aside without difficulty, remaining inside the machine. In addition, a new doctor blade support has been designed which can be removed without having to disconnect the inking system lines. Changing anilox and plate cylinder sleeves in just a matter of minutes is now pos- sible, thanks to clamps that are opened manually, simply and quickly. Rather than reducing the durability of the system, this simple and easy-change design has increased durability. The plate cylinder mandrels and anilox are held in place by nee- dle bearings specially sized to allow overhanging suspension and pneumatic supply that forms an air barrier--the elements required for sleeve changes. This bearing positioning ensures a high stiffness, while allowing for transverse movement of the plate cylinder roller for transverse registration between colors. The doctor blade is assembled in a closed swinging cham- ber mounted on linear guides, with horizontal movement and fine manual adjustment against the anilox. The system has been specially designed to maintain the inking position with the minimum blade pressure against the anilox. Disas- sembling the system is easily achieved without any need to disconnect the inking lines, greatly simplifying all cleaning Printing decks, adapted for front-side/horizontal mounting, are positioned in a radial pattern situated in the central drum. the design creates easy access for maintenance and daily operational needs and allows most regular operations to be completed rapidly and easily. Changing the blade is fast and safe thanks to patented technology consisting of a tool-free magnetic changing system. Changing the shutters is also conducted without tools, Making for quick blade swap-outs, that can be completed quickly, on the machine or outside of it.
