The Stack 2020 system operates in line with web-fed digital printers at speeds up to 450 ft/min. The system delivers 1-up, 2-up or 3-up offset stacks ready for binding utilizing the Buffer 530, Cutter c20 and Stacker s20 units. The optional Merger m20 allows 2-up print to be delivered in a single collated stack ready for inserting.
All modules in the Stack 2020 system incorporate Smooth-Web™ motion technology to gently transport paper from the printer to stacked output. This synchronization of the entire web to changes in speed provides unprecedented reliability and drastically reduces the likelihood of any paper jams. The Buffer 530 accumulates the paper 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 c20 utilizes a rotary knife to sheet the web and slit for 2-up or 3-up print streams and offsets the entire web horizontally to separate jobs or book blocks before sheets enter the stacker.
