Abstract
Multiple, single fiber webs, consisting of parallel fiber bundles and non-wovens connected by an adhesive thread grid, positioned on a common shaft for simultaneous unwinding. The single webs are dispensed under tension from a primary unwinding drum while, in the same process, an additional adhesive thread grid of non-woven or fiber mat is dispensed and, using tension winding, combined with the single webs into a homogeneous laminate.
