PURPOSE: To certainly connect sheets at a high working speed without generating a clogging problem in a drilling tool and to form relatively small connecting holes. CONSTITUTION: In the connection of printed matter 14 consisting of a large number of sheets, the sheets are bonded mutually in a spot like state by introducing an adhesive into the holes formed to the sheets. At this time, the adhesive applied to the outer periphery of a drilling needle 20 is transferred to the sheets 14 over the total length of the holes simultaneously with the formation of the holes by the needle 20 or at a time of the pull-out of the needle 20. |
