A production installation (21) produces book blocks (22) in parallel from digital prints on basic sheets (24). Each book block has "n" book sheets aligned through rows (46) and columns (44) and each basic sheet has "m" book sheets (43) equal to the number "m" of book blocks to be produced. Under the control of an electronic unit (56), a point bonding group (51) dispenses adhesive strokes (61) on the basic sheets across the rows and/or the columns, a stacking group (52) stacks the basic sheets and forms a basic block (62) stabilized by the point bonds, while a separation group (53) cuts and separates the book blocks from the basic block along the rows and the columns for following treatments. The basic sheets have machine-readable basic codes (68) and the electronic control unit actuates the point bonding group, the stacking group and the separation group on the basis of information derived from the basic codes.
