In-line or offline single cutting cut and stack solution for web-fed digital printers at speeds up to 450 ft/min

The Stack 2020 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.

Modular System Options

Slit Merge

The Merger m20 option allows a 2-up printed web to be slit and merged into a single, collated paper stream. Positioned before the Cutter c20, the web enters the Merger m20 and is slit in the center. A sensor continuously monitors the web for side-to-side variations or movement and the slitter automatically adjusts to cut precisely at the center of the web. The resulting two webs are then merged right-over-left or left-over-right, depending on the requirements of the application.

In-Line Finishing

The Feeder 568 option delivers individual sheets from the Cutter c20 to a third-party finishing device such as a saddle-stitcher or signature folder. It is installed in conjunction with the Stacker s20 to also allow normal offset stacking, thus providing users with high finishing flexibility.
