KOLBUS Sequential Feeder SF 842

For sequential separation of digitally printed and folded sections at a rate of 3,000 to 6,000 stacks/h.

The newly developed, high-performance SF 842 sequential feeder can be linked inline with a digital press and folding machine. System performance can be increased still further by using 2 or more feeders in parallel. Individual modules can be automatically fed offline using an STA 842.SF bundle feeder.

The digitally printed signatures are processed sequentially in parallel and collected in a magazine to form a complete book block. The system uses thickness measurement and start/stop recognition via print marks and/or barcodes. Automatic systems capture block thickness and correct the settings (by adding the absolute values) transmitted for subsequent processing in the Bookjet® perfect binder KM 200.
