One in three KBA Rapida 105 Sheetfed Presses Offers “No-sidelay Infeed”

In traditional mechanical or pneumatic sidelays, such as those still the norm even in modern sheetfed offset presses, the incoming sheet is first braked, then stabilized in the front lays, and then aligned at the sidelay tabs. This happens in a pulling process involving many subsidiary steps before the sheet goes through the swing infeed. In KBA’s SIS, a sensor continually scans the edge of the sheet. This eliminates the risk of the scanning result being negatively influenced by the paper fibers. The gripper bar is prealigned in the single-revolution transfer drum according to the information transmitted about the position of the sheet edge.
