Illustrative graphicSignature gathering
The Signa 5K-RH inline gatherer has 20 stations. Folded signatures are collected in sequence to form a book block that moves directly toward stitching or the perfect binder, with a maximum gathering thickness of 50 mm.
Illustrative imageCamera-assisted verification
The BSRS (Bindwel Signature Recognition System) uses a camera and is designed to identify gathering errors. The line includes a reject gate for books that are flagged. Like any inspection system, it supports quality control and does not remove the need for checks.
Illustrative imageStitching and pinning
A side stitching attachment with Hohner stitching heads allows stitched work on the line, and the gatherer supports pinning at a mechanical speed of 1,600–2,500 cycles per hour. The book block feeder handles thread-sewn and stitched books.
Illustrative graphicPerfect binding
The Freedom 5K is an inline automatic high-speed perfect binder with 12 clamps, handling spine thicknesses of 3–50 mm. It binds the gathered book block into an adhesive-bound book.
Illustrative imageAutomated trimming
The Trimit 50C is an inline high-speed three-knife trimmer running at 20–50 cycles per minute. It trims bound books on three sides, accepting untrimmed books up to 410 × 320 mm.
Illustrative graphicInline transfer
An inline conveyor carries books from the binder to the trimmer, connecting binding and trimming into a single continuous line.
