Abstract
Abstract An athletic mat is made up of uniform plastic foam slabs that are coated with plastic on each face and covered with adhesive along their edges. A mat of the desired shape and color is then assembled by abutting adhesive coated edges of selected slabs to bond together the foam; and the plastic coatings on each face of the bonded slabs are heated, and a heated plastic tape is pressed against the heated coatings to form a fused union between the tape and the coatings on each face of the slabs. The top and bottom coatings along the peripheral edges of the mat are heated, and a heated edge tape is formed into a channel shape and pressed over the peripheral edges and against the heated plastic coatings to form a fused union between the edge tape and the plastic coatings.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
30 words
The method of claim 1 wherein said coating is plastisol, and said plastisol is heated to form a solid, plastic coating on said slab without substantially softening said foamed plastic.
Claim 2
Dependent Claim
13 words
The method of claIm 2 wherein said seam and edge tapes are feather-edged.
Claim 3
Dependent Claim
13 words
The method of claim 2 including using radiant heat for heating said plastisol.
Claim 4
Dependent Claim
13 words
The method of claim 1 wherein said seam and edge tapes are feather-edged.
Claim 5
Dependent Claim
29 words
The method of claim 1 wherein said adhesive is applied to all edges of said slabs to form an adhesive bond between said foamed plastic and said edge tape.
Claim 6
Dependent Claim
54 words
The method of claim 1 including heating said plastic coating of said mat along a line to be marked on said mat, heating a plastic marking tape, and pressing said heated marking tape against said plastic coating along said mark line to form a fused union between said marking tape and said plastic coating.
Claim 7
Dependent Claim
33 words
The method of claim 1 including confronting a pair of edge-taped portions of said mat along a hinge line, and securing a fabric hinge strip across said hinge line of said mat portions.
Claim 8
Dependent Claim
20 words
The method of claim 8, including coating said fabric hinge strips with plastic before said adhesion to said mat portions.
Claim 9
Dependent Claim
37 words
The method of claim 1 wherein said seam tape is pressed in place by a heated roller on a portable tool that includes a heated platen for heating said plastic coatings for fusion to said seam tape.
Claim 10
Dependent Claim
46 words
The method of claim 1 wherein said edge tape is applied by feeding said abutting slabs through a machine that heats said plastic coatings along said peripheral edge, heats said edge tape, and presses said edge tape against said heated plastic coatings along said peripheral edge.
Claim 11
Dependent Claim
30 words
The method of claim 11 wherein said coating is plastisol, and said plastisol is heated to form a solid, plastic coating on said slab without substantially softening said foamed plastic.
Claim 12
Dependent Claim
18 words
The method of claim 12 wherein said seam and edge tapes are feather-edged and formed of said plastisol.
Claim 13
Dependent Claim
13 words
The method of claim 2 wherein said seam and edge tapes are plastisol.
