Abstract
An endlessly circulating conveying device is provided for strengthening a conveyable fiber lap. The device has first and second converging rollers for conveying the fiber lap. Each roller has an outer surface and at least the first roller is provided with profile elements on its outer surface. The rollers are for subjecting the fiber lap to a pressure when the fiber lap passes through a gap between the rollers, and strengthening the fiber lap by exerting the pressure by the converging rollers and the profile elements.
