Slit-merge and double cutter on the TC 7800 system
The High-Speed TC 7800 book-block production system from Tecnau increases web speed and reduces book block assembly cycle time, resulting in a throughput improvement of up to 30%.
Mainly targeted as a roll-input channel for the Libra 800 book finishing solution, the new system was developed to meet customer demand for more variable and productive solutions.
Configured with a high-speed unwinder, slit-merge and dual web cutter, the system can produce books-of-one variable in height, width and thickness at speeds up to 180m/min. Based on the Cutter TC 7800 series, the system includes a new tight web merging module, which ensures stable paper handling at high speeds over a broad paper weight range, from lightweight to heavy stocks.
The new system supports web widths up to 640mm and can also produce book blocks to feed third-party binders, with fully automated non-stop book-by-book delivery, or can be used as a standalone production line for short runs.
