The Stack 2330 system for color printers operates in-line or near-line with web-fed digital printers at speeds up to 550 ft/min. The system delivers 1-up, 2-up or 3-up offset stacks with variable full bleed cuts utilizing the Buffer 530, Cutter c23 and Stacker s30 modules. The optional Merger m20 allows 2-up print to be delivered in a single collated stack ready for inserting.
The Stack 2330 system incorporates SmoothWeb™ motion technology to gently transport paper from the printer to stacked output. The Buffer 530 accumulates the web and weaves it through rollers that rise and fall, filling the buffer and ensuring that stack deliveries will never stop the printer.
The Cutter c23 has dual rotary knives to sheet the web using single cut or variable double strip cut for full bleed color printing. Center slitting is also performed for 2-up or 3-up print streams and instantaneously offsets the entire web horizontally to separate jobs or book blocks before sheets enter the stacker.
Following the Cutter c23, sheets enter the shingling section of the Stacker s30 where they are gently decelerated and formed into a stack. This patent pending design maximizes control of the sheets and enables use of a wide range of media at high speeds.
