Andover, Massachusetts – March 8th – 10th in New York City, Standard Finishing Systems will show the recently introduced Standard Horizon StitchLiner, which bridges the production gap between existing flat sheet collating / bookletmaking systems and conventional high-volume saddlestitching lines. Offset or digitally printed flat-sheet signatures are fed from the Standard Horizon 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.
The StitchLiner features automated set-ups via a user-friendly touch screen control panel on the SPF-30 saddlestitcher, with job changeovers for the entire line accomplished in less than two minutes. After the operator inputs the job information, the system calculates and sets the position for size and register, scoring and folding, stitcher heads & clinchers, stitch wire length, the gap of the spine-pressing rollers, and positioning for head, foot and face trimming knives. The StitchLiner’s icon-based intelligent interface can also be integrated into Horizon’s CIP4-compatible “i2i” system, allowing job set-up data to flow from a centralized production control station, with remote set-up and monitoring.
Flat sheets (4-page sections) are fed from the SpeedVAC and collated into sub-sets. The sub-set is jogged, registered and transported at a right angle through a set of scoring rollers. It is then plow-folded and placed onto a saddle until remaining sub-sets (if any) have been delivered on top. When the complete set has been assembled, the saddle conveys the book block to the stitching area. After stitching, the booklet is conveyed through a set of steel spine-pressing rollers to the 3-knife trimmer where it is three-side trimmed. An optional set of center-cut knives and two extra stitch heads may be fitted for true two-up production with full bleed trimming. An advanced error detection system with automatic reject insures that only 100% accurate books are presented to the exit conveyor.
According to David R. Reny, vice president and managing director, Standard Finishing Systems, “The StitchLiner’s speed and quality bring a new level of productivity and professional finish to short-run bookletmaking. Printers and trade binders can avoid signature folding steps and pre-trimming of flat sheets, and the system delivers fast, easy changeovers for maximum efficiency. By eliminating production steps and minimizing changeover time, Horizon has provided a short-run solution that adds more value to the finished product.”
