ABSTRACT OF THE DISCLOSURE A method and an apparatus is disclosed for forming a multi-layered container of compressible sheet layers, such as corrugated board. The containers are formed in a single operation and avoids the known techniques of folding the layers before laminating in multistep methods. Furthermore, the container may be folded without the layers separating. The method of forming a multi-layered container having a plurality of flat sides with corners between adjacent sides comprises winding compressible sheet layers on a forming mandrel. In the process, one edge of a layer is attached adjacent to a corner of a mandrel, a shoe plate applies pressure to the layer against the mandrel as it rotates to maintain a substantially constant pressure and tension on the layer. An additional momentary force is applied to the shoe plate as each corner of the mandrel passes over the shoe plate such that the layer at each corner is compressed.
