<p>Apparatus for insertion of at least one flexible sheet (12) into at least one container (60) comprises a sheet grasping surface (22) having a plurality of undulations on it which cause the effective width of a sheet maintained on the surface by vacuum ports (50) to be reduced, so as to facilitate insertion of the sheet into an aperture (60) in the container. Sheets (12) are provided to the sheet grasping surface (22) from a magazine by a pick and place device (24). The sheet grasping surface (22) is formed on a thin plate member (20) which is moved by conveyor belts (62) to slide the plate into the aperture (60) in the container, whereupon the sheet is released from the surface and remains in the container on subsequent retraction of the plate. Prior to insertion of the plate (20) the container (18) is located by a grasping device (52) which bends the container to expose the aperture (60). The apparatus provides for simultaneous insertion of several sheets in a corresponding number of containers. The containers may be video cassette containers or envelopes and the flexible sheets may be cardboard title inserts or letters respectively.</p> |
