KBA Introduces Enhancements to the Rapida 106 PressMarch 23, 2011
DriveTronic SIS no-sidelay infeed
Although it is no longer brand new, the DriveTronic SIS (Sensoric Infeed System) is still unique on the market. Makeready-free, the system knows no setting or sidelay errors, nor does it mark sensitive substrates. Its mode of operation is ingeniously simple: a sensor determines the lateral position of the sheet on the feeder board, and as the sheet approaches the transfer point to the first printing unit the gripper on the transfer drum aligns the sheet with the side position specified at the console. The sidelay pull is ±5mm (0.2˝). Sheet transport to the infeed line is supported by vacuum-controlled thrust elements, which ensure that the sheets are guided gently to the front lays. This investment in disruption-free production is well worthwhile.
DriveTronic SPC dedicated drives
With DriveTronic SPC (Simultaneous Plate Change), each plate cylinder has a dedicated drive, with no clutches or auxiliary drives. The absence of a mechanical connection between the plate cylinder and the Rapida’s gear train means that almost all makeready processes can run simultaneously. This saves time. Because sequences run simultaneously, the time required for plate changes no longer features in the calculation: to all intents and purposes it is zero seconds, irrespective of the number of printing units. In tandem with the CleanTronic Synchro high-speed washing system DriveTronic SPC enables the benefits of dedicated drive technology to be exploited to the full.
Simultaneous washing with CleanTronic Synchro
CleanTronic Synchro is a two-bar washing system. The bar for the blanket is located above the impression cylinder and is easily accessible. The second bar is below the impression cylinder and can be removed from the press quickly and easily via rails. The washing programs for each printing unit can be preselected individually. With CleanTronic Synchro, the washing and plate-changing processes can run simultaneously. The diagram below illustrates a typical makeready process and reveals the potential savings that can be made in conjunction with DriveTronic SPC dedicated drives. The two-minute time gain for each job change translates into a saving of 33 hours after 1,000 job changes.
