The multi-sheet, folded printed product arranged on the supporting member is penetrated by a penetration tool, from the direction of a supporting member. A pressure-exerting element acts on the printed product with a lateral compressive force. This results in a widening of the through-passage produced through the printed product. Upon withdrawal into the rest position of the penetration tool, adhesive present on the surface of the penetration tool is transferred onto the sheets in the through-passage. Once the lateral compressive force has been eliminated, the through-passage closes, which results in good distribution of the adhesive and reliable adhesive bonding.
