A post-processing apparatus comprises a first processing tray on which fed paper is placed; a paper binding section configured to bind a plurality of sheets of paper stacked on the first processing tray into one bundle; a second processing tray which a plurality of paper bundles bound on the first processing tray are sequentially conveyed to and placed on; a paper bundle gluing section configured to coat glue at a given position of the top surface of a first paper bundle placed on the second processing tray before a second paper bundle is placed on the first paper bundle; a pressing section configured to press and bind the first paper bundle with the second paper bundle between which glue is coated; and a control section configured to control the timing for conveying the second paper bundle onto the first paper bundle after the glue is coated.

The present invention concerns the high speed packaging of folded paper articles such as tissues, napkins and the like, and more precisely it concerns an apparatus for continuously feeding such articles, arranged in stacked groups(P, P1) coming from folding machines, towards packaging machines, for example with a rotating drum, arranged downstream.
