The Alpha Saddlestitcher is a fully automatic, high speed, heavy-duty saddlestitch bookletmaker that can produce up to 6,000 books per hour. Its three-knife trimming and saddlestitching modules produce full-bleed flat books. Each parallel tower configuration has its own individual set transfer unit and folder and scoring unit, allowing for two complete sets to be transported simultaneously onto the saddle. Folded and scored sets are then transferred onto the moving saddle by a belt and finger system, with no risk of losing set registration even when feeding from multiple towers.
The modular design allows it to be configured as needed, with optional units such as the gutter cutter for two-up applications and a pre-collated sheet feeder. No adjustments for belt pressures, book retaining guides, or book thickness are required. Accepting a range of media, the Alpha can process sheet sizes ranging from 5.51x8.11" to 13.90x24.20" and deliver booklets of up to 200 pages.
