Abstract
An apparatus for glueing together two different material layers, of which one is intended to form a first cover in a folder, file or the like and the other a second cover and/or a spine in the folder, file or the like, the glueing being carried out in an area where the layers overlap each other, by a glueing device included in the apparatus, said device coating one side of one layer with a glue strip along or close to one edge thereof. The apparatus also includes an aligning means (23, 25), which aligns both layers relative each other so that they overlap each other in an area which is at least as wide as the width of the glue strip, a pressing means (26, 28) pressing both layers towards each other in the area for the glue strip therebetween, and a feed means (6-10, 15-18, 29-32) for feeding the layers through the apparatus.
