StreamFolder 5152 plow-folds the web once or twice along the travel direction, enabling efficient use of a web-fed press at its maximum print width. This folded web is very strong as the paper is up to three times thicker for system reliability (especially for lighter weight papers) feeding through the cutter and stacker.
The system efficiently produces short-run digital book printing jobs of varying run lengths including ‘books of one.’ Available with a tack-gluing option, the StreamFolder 5152 operates, in-line or near-line, at speeds up to 230 mpm (750 fpm) to take full advantage of the emerging generation of high-speed inkjet presses.
In addition, all modules operate in taut web to generate the exceptionally smooth paper ﬂow required for high-speed operations. Curl is cancelled out as the web is folded back onto itself, for reliably flat books. The StreamFolder 5152 also features ‘north/south job offsetting’, offsetting sets/book-blocks back and forth in the direction of travel to maintain full speed even for multiple consecutive small sets.
The system includes Tecnau’s StreamFolder f50 plow-fold module, Cutter c51 single-cutting cutter, and shingling Stacker s52. StreamFolder f50 is based on Tecnau’s popular and proven StreamFolder f20 product, with a next-generation controls package enabling Internet of Things connectivity, offering features such as remote monitoring and diagnostics and automatic software updates. Stacker s52 offers a tack-gluing option to keep loose sheets or signatures together for automated conveying to an inline perfect binder or other finisher, or to maintain book block integrity and registration during manual handling. An optional signature jogger also may be added for signature registration.
