ABSTRACT:
Method and apparatus for producing a protective covering for beds or the like comprised of a first thermoplastic web, a pair of fibrous mats of substantial loft, said web and mats being bonded together in accordance with a quilted pattern utilizing a thermoelectric bonding technique. The bonding layer, which is preferably polyurethane or a derivative thereof, forms an excellent bond with both the web and the fibrous mats. The fibrous mats provide excellent moisture absorbency and are breathable since the fibrous mats are bonded to the web only at the limited areas defined by the pattern. The first web provides an excellent waterproof barrier, while the mats provide an array of puffed-up regions each delineated by the bonding pattern to yield an aesthetically appealing cover which may be used with either fibrous web exposed. The web is of a color which makes an aesthetically pleasing contrast with the colors of the mats to yield an aesthetically pleasing protective cover in which the color of the moisture barrier layer "bleeds through" the moisture absorbing layers to yield an aesthetically pleasing product.
