Libra One is a complete and integrated system for producing pre-glued book blocks, ready for nearline binding.
Libra One can operate inline or nearline to digital printers at speeds up to 130 m/min (430 ft/min). The system starts from a roll up to 19.7” wide, printed in 2-up and 3-up, and generates 12 page and 18 page signatures.
Each book block can be composed of a variable number of signatures, and each signature can vary in length to produce book blocks on demand, variable in thickness and size.
Book blocks are pre-glued and offset-stacked to facilitate operator handling and transportation to the next finishing phase.
With its innovative processing (patent pending) and on the fly adjustment of cross and vertical perforation position, along with dynamic length cutting and folding, Libra One supports mixed impositions in the same roll with on the fly change from 2-up to 3-up, fully automated and at speed.
In a unique feature of Tecnau’s Libra One, waste pages are minimized by reducing the size of the last signatures. Depending on the number of pages of each book, the last signatures may be shortened in length to 8 page (2-up) and 12 page (3-up) signatures, minimizing the number of white pages at the end of each book.
