Performa 74 now also with automatically convertible perfecting
Press release from the issuing company
From December 2006, KBA will also be supplying its Performa 74 press with inline sheet-turning facilities for high-quality perfecting. The first successful customer installations, for example at Luthe Druck und Medienservice in Cologne, have demonstrated the potential of the Performa 74 for even greater flexibility and productivity.
The precise three-drum perfecting unit of the Performa 74 stands out with impressive substrate flexibility and register accuracy. The presses with up to six printing units and a maximum printing speed of 13,000 sheets per hour promise economical handling of the most varied substrates between 0.05 and 0.6 mm, in both straight and perfecting modes.
Whether lightweight paper or rigid board, the sheet-turning principle of the Performa 74, with a double-size transfer drum as well as double-size storage and turning drums, guarantees high functional reliability. The gripper system of the storage drum permits optimum smoothing of the sheet in both axial and running directions and exact transfer to the pincer grippers of the turning drum.
A special ink-repellent coating on the surfaces of the transfer and turning drums in the perfecting unit, and then subsequently also on the impression cylinders following perfecting, is the basis for maximum quality in perfecting work also at high speeds. Cleaning and maintenance requirements, furthermore, are reduced significantly. Sheet guide plates with fans after the perfecting unit and between the individual printing units provide for contact-free and thus mark-free sheet travel through to the delivery, while at the same time stabilising sheet transport for light substrates and high production speeds.
The conversion between the straight and perfecting modes is accomplished fully automatically from the touchscreen at the delivery. This high level of automation ensures fast makeready, ease of operation and maximum productivity.
