print head at either side of the page this would greatly reduce the likelihood of adhesive blockages in the flow channels the adhesive or respective parts of a two part adhesive can be provided in a chamber of a replaceable ink cartridge providing ink to the print head the print head 13 should be as close a possible to the pinch rollers 12 this is because the rollers 12 provide a mechanical constraint upon the page 11 to enable accuracy of printing the pinch rollers 12 print heads 13 and adhesive applicator 16 are illustrated in fig7 alongside a page support tray 18 that is the page support tray 18 receives pages 11 that exit the paper path 10 the tray 18 is suspended from a frame 21 by means of respective dampers 22 at each corner the dampers could be elastomeric dampers or small hydraulic or pneumatic cylinders for example the floor of tray 11 is not level it has a lower most corner 23 beneath which there is provided a vibrator 19 the vibrator 19 might be a subsonic vibrator ie a vibrator having a frequency below 20 hz or an out of balance electric motor for example a binding press 20 is situated above the tray 18 over the at rest position of the respective leading edge of the pages 11 however as an alternative the binding press 20 could be provided so as to be situated over the trailing edge of the pages in fig8 a first page 11 is shown in its trajectory toward tray 18 page 11 has a strip of adhesive 17 on its upper surface adjacent the leading edge the page 11 might tend to catch a pocket of air beneath it as it floats into position and the leading edge 28.
