US Patent 7793926 Page stacking and binding apparatus

A page stacking and binding apparatus for stacking and binding pre-glued pages includes a frame. A support tray is mounted on the frame and is configured to receive the fed pages such that the pages fed into the tray can rest in an aligned condition. The support tray is movable with respect to the frame. A vibrator is engaged with the support tray to impart vibratory movement to the support tray so as to facilitate said alignment. A binding press is operatively positioned with respect to the support tray to press the aligned pages against each other.
