A straight-line insert machine for inserting materials (600) into a newspaper jacket (100). The jacket is positioned in a moving pocket (300) which is hinged but closed at the bottom such that when the pocket opens, as vacuum is applied to the walls of the pockets, the jacket opens. Vacuum flanges moving at the same linear speed as the pockets mate with vacuum stems attached to the pockets for a predetermined time and apply vacuum to the walls (320, 340) of the pocket so that the front and rear portions of the newspaper jacket are held against the fixed (340) and movable (320) walls, respectively, as the pocket opens. The pockets and vacuum system are synchronously driven. Camming action is used to open and close the pockets. Insert hoppers (500) place insert materials into the open jackets. Because the machine is modular, additional insert hoppers and pockets can be added. A gripper-conveyor system (700), which is also synchronously driven with the pockets and vacuum system, picks up the newspaper with inserts from the top of a closed pocket and delivers the newspaper with inserts to a drop-off point such as a tray (780) or a stacker. |
