Method and apparatus for pin-hole prevention in zone laminates
Abstract
The method and apparatus of the present invention prevents the formation of pin-holes during stretching of strip laminates in the cross-machine direction (CD). Pin-holes are prevented by creating slack areas (10a) along the length of the laminates (10) where the edges of the non-woven strips (14) meet with the polymer film (12), pressing the slack areas (10a) into the interdigital stretching rollers (26) without stretching the slack areas (10a), and stretching the remainder of the laminate (10) in a typical manner. The slack areas (10a) are formed prior to interdigitation by, for example, formation of a furrow, a fold or a corrugation.
