Abstract
A method of forming wood flooring. The flooring has foam applied to one side by adhesive. The adhesive is cured and a chemical bond forms between the wood and foam to provide a consolidated unit. This facilitates easier cutting of the consolidated product without dissociation of the foam from the wood. The result is an improved flooring product having sound suppression qualities.
Description
1 File No. 9-16066-4CA-1 SOUND SUPPRESSING FLOORING AND METHOD OF
MANUFACTURING SAME
The present invention relates to a flooring product and, more particularly, the present invention relates to a sound suppressing flooring arrangement.
Wood flooring is clearly attractive in a home and in most instances such flooring adds value to a house or other structure within which it is placed.
A characteristic of wood flooring is a lack of sound suppression. In view of the fact that the flooring is hard, acoustic transmission is very high. Attempts to circumvent this problem have been proposed in the art. One solution previously presented involved the use of underlayment. This proved to be useful; however the solution presented another complication, namely installation of the two materials.
Any form of underlay is difficult to position properly and this situation is compounded with the exactness required for hardwood flooring positioning.
Other efforts to formulate such products have developed into wood planks having rubber or foam attached to the floor facing side. The difficulty here is that the rubber often becomes disconnected from the wood during shipping thus leading to on the spot repairs or waste from having to discard the product.
It would be desirable to have a flooring product capable of retaining a sound insulation function together with a high degree of consolidation with an organic foam backing. The present invention addresses this need.

curable adhesive to a major face of said major faces to form a chemical bond therewith; and a plurality of spaced apart air cells between said major face of said wood member and said cross linked polyolefin foam material adhesively engaged to said major face which includes the air cells.
The provision of a texture allows for a random or alternating pattern of adhesive surrounding closed air cells. The cell of air is effectively encased by a cured adhesive, the foam and the wood panel major face. This results in a lighter flooring panel or other such panel which can be used in different constructions and further provides a high degree of insulation with an increased R
value over existing arrangements. In terms of the texturing, the same can take any suitable shape and may exist in any pattern, i.e. a regular pattern with a textured section followed by a non-textured and subsequently with a textured section or any variation on this or further, even any random pattern. This will depend on the final use of the product.

providing a source of wood suitable for use as flooring;
applying an adhesive material to one side of the flooring to effect chemical fusion between the flooring and the foam, and

cutting the wood having said foam consolidated there with into segments for flooring.
Suitable adhesives include MapeiTM #965.
In view of the fact that the flooring product is mold, mildew and moisture resistant, no vapor barrier is required.
In respect of the foam, examples which have provided the desired combination of factors include polyamide foam, polyethylene/polypropylene blends, such as that manufactured by Toray Plastics (America), Inc., and Voltek, a division of Sekisui America Corp. Other suitable examples of closed cell polyolefin foams will be appreciated by those skilled in the art.

5 numerals.
The process to effect the formation of the plank is illustrated in Figure 1. Numeral 10 references a material supply, in this case wood flooring, to be exposed on one side to adhesive at 12. Once the adhesive has been applied, the material is passed to a foam application stage where foam 14 is applied to the adhesive surface to chemically fuse with the foam. Preferably, the adhesive is an ultraviolet curable adhesive for effecting fusion. The product is subsequently cut at 16 into a desired shape. In this case that shape is planks for use as flooring. For enhanced consolidation, the cut material may be pressurized at 17 by roller nibs (not shown) or other suitable means such as gas pressurization or vacuum. This operation has the benefit of ensuring that the maximum degree of contact is attained between the wood and foam material by forcing any trapped gas out of the interface between the materials.
As an optional step, the cut planks may be heat treated at the edges, globally indicated at 18 in order to melt or otherwise thermally degrade the material. This has the advantage of toughening the material to prevent disengagement from the wood plank, referenced by numeral 20 in Figure 2.
Having set forth the details of the invention in one embodiment, reference will be made to the table below

Referring now to Figure 4, shown as a further embodiment of the present invention where the foam material 14 includes a texture 22, shown in Figure 4 as short line segments and in Figure 5 as a circular or spherical pattern. It has been found that by providing a texture, adhesive material effectively alternates with the texture as shown in Figure 6. This, accordingly, provides sections of individual air pockets or cells 26 dispersed amongst the adhesive and foam material. Advantages have been realized in terms of enhancing the surface area for bonding to the flooring material with a concomitant reduction in the amount of adhesive required while providing enhanced surface area. Further, by making use of the air pockets, a greater degree of insulation can be realized with the laminate wood flooring. This is particularly advantageous in situations where the laminate is used on radiantly heated flooring. In the absence of the air cell design according to this embodiment of the present invention, passive radiantly heated flooring does not provide for adequate heat efficiency.
In terms of the manufacturing, Figure 7 illustrates an example of a process that could be used to manufacture the material where the process is very similar to that previously discussed. In this instance, a further unit operation, globally denoted by numeral 26 may be included where the operation is directed to texturing the foam material. As a further option this step may be eliminated from the process and the texture imparted to the foam at 17 by providing textured nib rollers.
