Claims13
A method for forming a honeycomb-shaped core suitable for being included in a honeycomb panel, wherein webs or plates of deformable material are provided with continuously or otherwise extending glue strips, wherein, for every two plates or webs to be mounted onto each another, said glue strips are disposed in a laterally regularly mutually staggered manner on faces thereof having the same orientation and wherein the plates or webs are pressed onto each other in order to allow them to adhere to each other locally wherein the glue strips are applied by means of glue spout nozzles, wherein the glue strips each comprise two glue tracks which are laterally spaced and are kept spaced with their opposing longitudinal edges at a distance in the order of magnitude of a width of a side of a honeycomb cell.
Apparatus for use for forming a honeycomb-shaped core suitable for being included in a honeycomb panel, said core being composed of an expanded stack of bands of deformable material, said stack of bands being cut from a stack of plates of said deformable material, said plates being adhered to each other by means of glue strips applied on said plates, the apparatus comprising a conveyor for said plates and a glue station located above the conveyor for said plates, said glue station being provided with a series of glue spout nozzles arranged laterally adjacent one another and a primary glue supply means therefor, in which the glue spout nozzles are connected to the primary glue supply means in groups via secondary glue supply means, in which the secondary glue supply means are provided with selectively operable valves for passing glue.
