ABSTRACT:
A process for the manufacture of apertured, three-dimensional substrates having an extrusion coating material thereon, the coated substrate and an apparatus for making the coated substrate are disclosed. Successive portions of a continuous sheet of the apertured substrate which has a top surface and a bottom surface are passed into contact with a continuous moving perforated member. The coating material is supplied onto the top surface of the continuous moving substrate. The bottom surface of the substrate is subjected to a vacuum. The vacuum causes the coating material to flow onto the top surface of the substrate material and in certain embodiments, at least partially into the apertures in the substrate. The vacuum is maintained for a period of time sufficient for the coating material to bond to the substrate. The coated portions of the substrate are continuously removed from the moving member.
