Abstract (en)
1. A process for the continuous production of a corrugated member comprising a backing web (3) and a top web (2) which is arranged in a corrugated configuration on the backing web (3), wherein the top web is connected at connecting locations in the region of the depressions which extend transversely with respect to the direction of the web, by the backing web (3) being moved cyclically forwards relative to a shaping station (1) and the top web (2) which is to be connected to the backing web (3) being supplied from a feed means, and by the top web being deformed at the shaping station (1) by means of first and second pressing means (4, 5), over a deforming element (6) disposed between the two webs, and being pressed against the backing web (3) at the connecting locations, characterized in that at the shaping station (1), during a rest phase, a deforming element (6) is inserted laterally between the backing web (3) and the top web (2), that the first pressing means (4) which is downstream of the deforming element (6) in the direction of advance movement is lowered and then the second pressing means (5) which is upstream of the deforming element (6) in the direction of advance movement is lowered, in which operation the top web (2) is deformed and connected to the backing web (3), that the first pressing means (4) is raised and the deforming element (6) is withdrawn laterally, and that then the second pressing means (5) is raised and the backing web (3) is moved on by an advance step, and then the operation at the station begins afresh.
