Abstract
Abstract An adhesive backed removable carpet tile comprising a foam backing and a carpet layer is disclosed which may be applied to a subfloor and subsequently removed therefrom without delaminating the foam backing. The adhesive provides a release strength lower than the delamination strength of the foam backing. To provide the proper release strength, the adhesive is applied to the foam backing by a figurated roller to cover between 10 and 50 percent of the foam backing.

Claim 1
Independent Claim
111 words
A PROCESS OF APPLYING ADHESIVE TO A FLOOR COVERING HAVING A FOAM BACKING OF 8.5-19 POUND.CUBIC FOOT DENSITY AND A TRAFFIC BEARING LAYER BONDED TO THE FAOM BACKING HAVNG A DELAMINATION STRENGTH OF 1.0-2.25 POUND/INCH, THE PROCESS COMPRISING THE STEPS OF APPLYING AN EFFECTIVE AMOUNT OF A LIQUID ADHESIVE TO THE FOAM BACKING IN A MULTIPLICITY OF DISCRETE PORTIONS EACH HAVING AN AREA OF LESS THAN ABOUT 0.1 SQUARE INCHES AND SEPARATED FROM THE NEXT ADJACENT PORTION BY A ONPERCENT OF THE AREA OF THE FOAM BACKING; AND ADHESIVE AREA, THE PORTIONS AGGREGATING LESS THAN 50 SOLIDIFYING THE ADHESIVE TO PRODUCE A RELEASE STRENGTH FOR THE FLOOR COVERING BETWEEN .1-.9 POUND/INCH.

Claim 3
Dependent Claim
146 words
A process of applying adhesive to a floor covering having a foam backing of 8.5-19 pound/cubic foot density and a traffic bearing layer bonded to the foam backing having a delamination strength of 1.0-2.25 pound/inch, the process comprising the steps of placing a liquid adhesive having a dry tack level between 1.25-1.75 pounds/inch at .001-.002 inch thickness of application in a multiplicity of adhesive carrying cups provided by a roller, each of the cups having an area less than about .01 square inches and aggregating between 10-50 percent of the effective area of the roller; contacting the roller and the foam backing; transferring the adhesive from the cups to the foam backing to produce a multiplicity of discrete adhesive areas on the foam backing; and solidifying the adhesive to produce a release strength for the floor covering less than the delamination strength of the foam backing.
Claim 4
Dependent Claim
146 words
A process of applying adhesive to a floor covering having a foam backing of 8.5-19 pound/cubic foot density and a traffic bearing layer bonded to the foam backing having a delamination strength of 1.0-2.25 pound/inch, the process comprising the steps of placing a liquid adhesive having a dry tack level between 1.25-1.75 pounds/inch at .001-.002 inch thickness of application in a multiplicity of adhesive carrying cups provided by a roller, each of the cups having an area less than about .01 square inches and aggregating between 10-50 percent of the effective area of the roller; contacting the roller and the foam backing; transferring the adhesive from the cups to the foam backing to produce a multiplicity of discrete adhesive areas on the foam backing; and solidifying the adhesive to produce a release strength for the floor covering less than the delamination strength of the foam backing.
Claim 5
Dependent Claim
23 words
