Binding Equipment

The choice depends on the number of pages, desired durability and budget:

- Saddle stitch: 8-64 pages. Medium durability. Low cost. Magazines, catalogs, brochures.
- EVA hot melt (perfect binding): 40-400 pages. Medium durability. Medium cost. Paperback books, reports.
- PUR adhesive (reactive polyurethane): 40-400 pages. Very high durability. Medium-high cost. Reference books, premium catalogs.
- Smyth sewing (section sewn): 40-800+ pages. Maximum durability. High cost. Technical books, Bibles, premium materials.
- Folder-stitcher (booklet maker): 8-32 pages. Medium durability. Low cost. Booklets, manuals, newsletters.

PUR adhesive advantage: 40-60% higher resistance than EVA, does not crack over time, withstands extreme temperatures (-20°C to +80°C) and allows full book opening.

Yes, but it is necessary to check three parameters of the binder:

1. Milling capacity: high-grammage pages (>200 g/m²) or coated stocks require deep milling to expose paper fibers and ensure adhesive bonding.
2. Spine adjustment: thick materials increase the book block thickness, requiring a wider spine and feed clamp adjustment.
3. Adhesive compatibility: laminated or fully UV-coated pages may reduce adhesion. In these cases, PUR adhesive with aggressive milling or thread sewing is recommended as an alternative.

Supported grammages: most automatic binders process papers from 60 to 350 g/m² in the book block.

A folder-stitcher (also called a booklet maker) is a machine that combines folding and stitching functions in a single compact unit.

Advantages: eliminates the need for two separate machines, reduces manual handling between processes, increases productivity for runs of 500 to 10,000 copies and takes up less space in the print shop.

Ideal applications: informational booklets, product manuals, quarterly reports, small catalogs and promotional materials. Limitation: recommended for jobs up to 20 sheets (80 A4 pages), depending on paper grammage.

- Integrated Line: automatic workflow (collating → gluing → drying → three-knife trimming), productivity of 4,000-8,000 cycles/hour, minimal alignment errors, higher initial investment, ROI in 18-36 months for high volume.
- Standalone Machines: manual or semi-automatic workflow between stages, productivity of 500-2,000 cycles/hour, higher alignment errors, lower investment, immediate ROI for low volume.

SAGLIN recommendation: for runs exceeding 5,000 copies/month, the integrated line is more economical in the long run due to reduced labor and waste.

Not necessarily. Each method has its advantages:

- Smyth sewing: offers maximum durability and full book opening (180°). Indispensable for frequently consulted books, Bibles, dictionaries and collector's editions. However, the process is slower and more expensive.
- PUR adhesive: for most commercial and educational books, it offers adequate durability at 30-40% lower cost and 2-3x higher production speed.

Practical decision: if the book will be opened and closed hundreds of times → sewing; for continuous reading or occasional reference → PUR adhesive.
