Horizon Stitchliner 5500
The Standard Horizon StitchLiner bridges the production gap between existing flat sheet collating / bookletmaking systems and conventional high-volume saddlestitching lines. The StitchLiner eliminates signature folding as offset or digitally printed flat-sheet signatures are fed from the SpeedVAC collator to produce true saddlestitched booklets with full bleed trimming, at speeds up to 11,000 two-up booklets per hour. Professionally finished booklets up to 200 pages (50 sheets) are fully comparable with booklets produced by traditional saddlestitchers. Can also be equipped with the HOF high-speed sheet feeder for digitally collated output (up to 27,000 sheets per hour) with guaranteed document integrity using mark, bar code, or CCD camera verification.
