Abstract

The corrugated pipe is helically coiled from a sheet-metal strip having corrugations extending parallel to its longitudinal direction, in each case at least one corrugation of one side edge of a strip (1) being located in at least one corrugation on the other, overlapping side edge of the following strip turn. In order to prevent the corrugations, located one inside the other, of two neighbouring strip turns from slipping apart, even in the case of very thin sheet-metal strips or pipes of high flexibility, the corrugation peaks of the corrugations, located one inside the other, are pressed down, at at least one point on the pipe circumference, by an amount corresponding to part of the corrugation height such that, in the pressed-down region, the corrugation heads of two corrugations, located one inside the other, are wider than the corrugation necks located therebeneath, the corrugation which is respectively adjacent in the longitudinal direction of the pipe being unchanged at least in the region beside the pressed-down portion (2). <IMAGE>
