Abstract
A method of strengthening a conveyable fiber lap in an endlessly circulating conveying device is provided. The method includes conveying the fiber lap using first and second converging rollers, each roller having an outer surface, at least the first roller being provided with profile elements on its outer surface, the profile elements being non-continuous in an axial direction of the first roller; subjecting the fiber lap to a pressure when the fiber lap passes through a gap between the first and second rollers; and strengthening the fiber lap by exerting the pressure by the converging rollers and the profile elements.
