<p>In a packaging material made from dewatered pulp, said material being generally in sheet or web form and comprising a number of mutually intersecting, rectilinear rows of hollow posts (2), the main new feature is that at least one side wall (3) of each hollow post (2) converges towards the remaining side walls and/or forms such an angle (4) with the general plane of the material, that when the hollow posts on one piece of the material are inserted in the hollow posts on another piece of the material, the outside surface on said side wall or side walls (3) in said other piece enters into engagement with the inside surface of said side wall or side walls (3) in said first piece in such a manner, that the bringing together of said outside and inside surfaces will produce a locking interengagement between them. With this arrangement, a number of pieces of packaging material may be joined together so as to form sheets or webs of larger dimensions, especially for use as an intermediary layer between a packaged article and e.g. a corrugated-paper box, the dimensions of which usually differ from the dimensions of the moulds, with which articles of pulp are manufactured.</p> |
