Equipment / Further Details:
Line Configuration:
1.Roll-to-Stack Feed: Unwinder, merger, Dupla cutter, and book assembly station for the production of book blocks with 2-up printing.
2.Sheet Feeder: A variable number of loose sheets can be added as inserts to the book block. The sheets must have the same size and print run as the book block being processed.
3.Infeed to Binder: Manual feeding station for pre-fabricated book blocks, conveyor with scanning station, book turnover module, and robotic loader at the binder.
4.Variable Binder: For the production of softcover books. The binder is equipped with PUR for the spine and hot-melt glue for the side gluing.
5.Softcover Cover Feeder: Configured with a sheet cover feeder; pre-printed covers are fed, trimmed at the front, side-trimmed, and creased to the exact thickness of the corresponding book block.
6.Cooling Tower: Books are transported from the binder through the cooling tower to the three-knife trimmer.
7.Variable Three-Knife Trimmer: Suitable for trimming books with variable dimensions in three axes and different cover types.

Finishing Line
The entire process is controlled via 2D Data Matrix codes. Through the code, the system receives authorization for the following automatic settings and workflow control:
• Information on book dimensions and inserts (quantity and sequence)
• Binder setup (spine position, thickness, and length)
• Cover preparation: Softcover → creasing, cutting, edge trimming
• Correct book-to-cover matching
• Three-knife trimmer (blade positioning is automatically adjusted to the book dimensions)
