Beschreibung
Zusammenfassung:	The method of present invention comprises forming a mat of a plurality of layers of lignocellulosic material, having first and second outer surfaces. The mat includes first bands of an adhesive bonding material applied on at least one of the first and second outer surfaces, between each pair of adjacent layers, at a location extending adjacent to the longitudinally-extending outer edges of the product. Then, the plurality of layers of lignocellulosic material of the mat are bonded together to form the multi-layer lignocellulosic product which exhibits a relative small difference in the edge swell, after wetting, of at least one of the outer surfaces as compared to at least one of the longitudinally-extending and laterally-extending outer edges, respectively.
