PF7 Book production line

Roll unwinding is the first step in the production line. The Hunkeler UW7 unwinder unwinds the paper rolls with a web width of up to 762 mm (30 in). The subsequent PF7 Double Plow Folder is a double folding module designed specifically for book production. This unit enables the production of signatures with 1, 2 x 4 (double production), 6 or 8 pages. Depending on the paper grade and fold type, the PF7 double folding module can process substrates weighing up to 150 gsm. The following CS6 cross-cutting module cuts the folded paper web with a rotary action and the utmost precision.
However, the key to connecting the book production line to the adhesive binder in an inline configuration is the signature gluing process in the newly developed SD7 nonstop stacker. A starwheel delivery is used to gather the cross-cut folded sheets at a speed of up to 200 meters per minute and to create book blocks via the integrated signature gluing unit.
