A method of manufacturing the layer () in question, in which method at least two separate webs () of opened and into a layer spread-out tow are fed into a bonding station (), which webs exhibit different web tensions and/or web speeds, and that the webs () with maintained relative difference in web tension and/or web speed are bonded together in said bonding pattern () into a laminate.
