<p>Longitudinal corrugating system for laminar strips or webs, characterised by at least one roller or drum (1), around which are juxtaposed, in a sector of its circumferential area, a series of peripheral rollers (2) of smaller diameter which have some corrugating elements in the way of annular grooves which are increased in number from the first peripheral roller to the last; these peripheral rollers (2) are pressed against the drum (1) which has its surface profiled to correspond to the corrugating elements of the peripheral rollers (2) or is resiliently deformable to take the shape of the corrugating elements; all this in such a way that passing a laminar strip or web between the peripheral rollers (2) and the drum (1) causes a progressive corrugation of the said strip, with corrugations aligned in the direction of advance of the strip.</p> |
