Abstract
The present invention pertains to the art of floor coverings, and, more particularly to an apparatus for use in securing floor covering units to an underlay and a method of manufacturing said floor covering units and said underlay. More particularly, the present invention relates to an apparatus, method, and method of manufacturing magnetized floor covering units and magnetized underlays for securing magnetized floor covering units.
Claims18
A method for manufacturing an underlay comprising:
- blending a binding compound, the binding compound comprising a plasticizer and a magnetizable metallic compound;
- heating the binding compound to a semi-solid state;
- unrolling and stretching a scrim layer;
- continuously extruding the binding compound over the stretched scrim layer;
- spreading the extruded binding compound evenly over the stretched scrim layer;
- heating the binding compound and scrim layer as the binding compound and scrim layer pass through a heating element to set the binding compound into a solid state and form a combined binding compound and scrim layer;
- and pressing a vapor barrier layer onto the combined binding compound and scrim layer to combine the vapor barrier layer with the combined binding compound and scrim layer to form the underlay.
