<p>A plate assembly (2) and a method for manufacturing such plate assembly (2) is disciosed. The plate assembly (2) comprises: - a first plate member (4) provided with a number of protrusions (10) and a number of indentations (12) arranged side by side; - a second plate member (6) provided with: a number of protrusions (14) and a number of indentations (16) arranged side by side, where the protrusions (14) are configured to be mechanically attached to a corresponding number of indentations (12) of the first plate member (4), where the indentations (16) are configured to be mechanically attached to a corresponding number of protrusions (10) of the first plate member (4). The indentations (12, 16) and the protrusions (10, 14) are circular arced, and that the circular arcs of the indentations (12, 16) are basically equal to the circular arcs of the protrusions (10, 14). The smallest width (t) of the indentations (12, 16) corresponds to the radius (r) of the circie corresponding to the circular arc of the protrusions (10, 14).</p> |
