Standard Finishing Systems, a leading supplier of post-press and paper handling solutions, recently announced the release of the Hunkeler Starbook Plowfolder Book Block Solution which is designed to run inline or near-line in high-volume digital print environments.
The Starbook Plowfolder combines unwinding, plowfolding, dynamic cutting, and starwheel book delivery into a solution that produces glued book blocks from 4- , 6-, or 8-page signatures. On the front end, the Hunkeler UW8 Unwinder can handle web widths up to 22.5” and up to 1,980 lbs. For wider media or continuous production, the UW7 Unwinder, RS8 Automated Roll Splicer, or RX8 Automated Media Changer are also compatible. Next, the Hunkeler PF8 Plowfolder’s fold pressing units ensure a tight, high-quality fold. The PF8 also features a web guide for continuous fine adjustment of the web edge for accuracy and stability. In the cutting section, the Hunkeler CS8-B Rotary Cross Cutter converts the folded paper web into 4-up, 6-up, or 8-up signatures. The CS8-B’s Dynacut function allows for dynamic changes in signature cut length during continuous production. Book blocks are delivered individually or in stacks of multiple book blocks via the Hunkeler BD8 Book Delivery Module. The BD8, featuring Hunkeler’s patented starwheel delivery system and a modular design, delivers glued, flat book blocks with straight spines.
The Starbook Plowfolder Book Block Solution is optimal for short or long run lengths, including book-of-one and variable thickness applications. It can run at speeds of up to 820 feet per minute.
“We’ve already overseen the successful installation of two Starbook Plowfolder lines in North America since the end of 2022,” said David Reny, Executive Vice President, Standard Finishing Systems. “With book-of-one demand increasing alongside printer speeds, we’re excited to bring this powerful offering to the high-volume digital print industry.”
