Abstract
Apparatus for gluing together at least two individual sheets of material cut to finished dimensions and intended to form parts of a folder consisting of a spine and two covers. The apparatus includes two reception surfaces situated side by side, each defined by aligning members for aligning the two individual sheets in predetermined positions relative to each other. There is provided a first conveyor for moving one sheet away from its reception surface to a gluing device for coating at least one sheet with a glue bead and a second conveyor for moving the second sheet away from its reception surface. At least one of the conveyors is adapted to move one sheet relative to the other so that both sheets overlap each other in the area of the glue bead. A press is provided for pressing together both sheets in said area. The apparatus also includes locating devices which locate the sheets in said positions and are movable relative to each other and together with the respective sheet for maintaining the locations of the sheets during movement of the sheets, their gluing together and pressing together.
