ABSTRACT:
For manufacturing printed products such as books or booklets consisting of a stack of paper sheets adhesively joined together and folded along a middle line, a plurality of paper webs are brought together to form a stack of paper layers moving continuously. Into the continuously moving stack a liquid binder is injected along equidistant lines perpendicular to the moving direction of the stack. After binder injection, two,additional webs are brought together with the stack to cover the stack on both sides. Then the stack is cut midway between each pair of junction lines to form individual stacks and the individual stacks are folded along the junction line.
