ABSTRACT:
For the connection of the sheets of a multi-sheet printed product (14), such as magazines, brochures and the like, the sheets are adhesively connected together point-wise by the introduction of an adhesive into perforations formed in them. During this, the adhesive applied to the outer side of the penetration and drilling needles (20) is transferred onto the sheets over the whole length of the perforations simultaneously with the formation of the perforations by means of these needles (20) and/or on retraction of the needles (20).
