Abstract
A process and an apparatus for high speed manufacture of a composite sheet material, which includes a cylindrical cam-driven strand-traverse guide that can loop strands around pins projecting from a pair of advancing pin conveyors which can transfer the strands to the surface of a moving sheet, are provided. When the strands are elastic, the elastic composite sheet material made by this process and apparatus are useful in elastic components of disposable diapers, adult incontinence articles and other garments.
