The paper machine as in DT 1921378 for producing laminated fibre strip, particularly cardboard, comprises a series of superimposed, sieve sections each producing a separate layer, two successive sieve sections running in opposite directions and a sieve forming a combining zone for bringing the layers together, while two further successive sieve sections are displaced relatively in the length direction of the machine in such a way that they are only covered over a prt of their length particularly the region opposite the pulp feed, at least the uppermost of such sieve sections being supported on its own staging with its covered region projecting over the staging on which it is supported, and incorporates the improvement whereby the staging supporting an individual sieve section is arranged approx. at the same height as the upper strip-producing length of the next succeeding sieve section. |
