Production installation and method for block books in parallel from digital print

A production installation for book blocks in parallel from digital prints on basic sheets, wherein each book block has a given number “n” of book sheets and each basic sheet has a number “m” of book sheets equal to the number “m” of the book blocks to be produced and wherein said installation comprises a stacking group for the basic sheets, a separation group for the book blocks, and an electronic control unit for the stacking group and the separation group,

• the book sheets are distributed on the basic sheets by aligning through aligning rows and aligning columns and separation areas adjacent to the book sheets;
• and
• the stacking group is actuatable for stacking the basic sheets and forming a basic block;
• wherein
• the book blocks and the basic sheets are in association with data derived from machine-readable basic codes, while said installation further comprises a bonding station including a point bonding group for the basic sheets and code detectors for the reading of the basic codes;
• and wherein:
• the point bonding group is provided for dispensing adhesive strokes on the basic sheets across the aligning rows and/or the aligning columns, in correspondence of the separation areas, while the stacking group stacks the basic sheets, without sliding, forming said basic block in which the book sheets are aligned and stabilized by the adhesive strokes;
• the separation group is provided for cutting the book blocks from the basic block along the aligning rows and the aligning columns of the book sheets and separating said book blocks for following treatments;
• and
• the electronic control unit responds to signals from said code detectors for actuating the point bonding group, the stacking group and the separation group on the basis of information from said basic codes.
