StitchLiner Mark IV Saddlestitcher

Production speeds:

The Mark IV can run at speeds of up to 6,000 booklets per hour for A4 portrait applications and 5,300 booklets per hour for A4 landscape applications.

True variable production:

Stitch length, balance adjustment, registration guides, trim size, and more can all be changed automatically from booklet to booklet during operation for true variable booklet production.

Increased up-time:

The Mark IV can maintain production speeds even while in variable thickness mode or when cover sheets are inserted. The Mark IV can also run continuously even if a booklet with an error such as a dropped stitch or sheet misalignment is detected by seamlessly rejecting the booklet to a tray.

Consistent quality:

The Mark IV can stitch booklets up to 10 mm thick (about 50 sheets at 50lb offset). Across all booklet sizes, the system’s scoring function reduces cracking on the spine and allows for a tighter fold. Depending on the substrate, the gap and scoring pressure can be adjusted for consistent scoring quality. The sheet-alignment section of the Mark IV features 4-directional jogging for a tighter jog and more accurate alignment across stocks. Improvements to the Mark IV’s transport system also allow for stable sheet transport across substrates, even for coated sheets.
