The Swiss-based Model group’s Obaly plant in Opava, the biggest manufacturer of packaging in the Czech Republic, has installed a Rapida 106 with eight printing units, a coater, two dryers and a further printing unit. The new medium format press will be used mainly for “out-of-the-ordinary” luxury cartonboard packaging wich standard press configuration are unable to handle. It is also engineered to print flexible packaging.
The press operates with a DriveTronic SIS (Sensoric Infeed System) sidelay-free infeed. If necessary the plates can be changed simultaneously in all nine printing units via DriveTronic SPC. DriveTronic Plate Ident checks that the plates are allocated to the specified inking units for the job concerned, and automatically ensures correct preregistration with the aid of register marks on the plates. The CX board-handling capability enables the Rapida to handle sheets up to 1.2mm thick at high speeds. The 2.4m delivery extension guarantees that the freshly printed sheets are dried right through. And to accommodate the thicker substrates used in packaging production, the press is mounted on a 675mm plinth.
Model Obaly’s Rapida 106 is one of the first presses in the Czech Republic to incorporate a module for inline coldfoil stamping. Positioned above the second printing unit, the Vinfoil Infigo SF 110GF system with MFU (Multiple Foil Use) features automatic foil change, two turner bars for separating the foil and, with the MFU capability, a device for feeding the foil in as a double loop, reducing foil consumption by as much as 88%. With MFU the foil does not need to be unwound across its full width nor around its full circumference. Depending on the image, it can be used several times over.
The press run is monitored by a camera-based QualiTronic Professional inline sheet-inspection system and the investment package also includes an automated logistics system for substrate transport at the feeder and the delivery. Despite the Rapida’s length and complex configuration, its maximum production speed is 15,000 sheets/hour, with or without coldfoil stamping.
