Reinforced synthetic inlays and seams
View Patent ↗A reinforced seam/inlay and method for forming such seam/inlay to join pieces of synthetic turf material together are disclosed. The reinforced seam/inlay structure comprises abutted edges of first and second synthetic turf pieces having a backing joined together; a seaming cloth/tape material coated with an adhesive/glue, volatile solvent or heat activated material applied is positioned beneath the abutted edges of synthetic turf pieces wherein said abutted edges are adhered to said seaming cloth/tape material; and reinforcement fastener elements inserted through both the backing of the synthetic turf material, through the adhesive and the seaming cloth/tape material; or seam/inlay structure comprises of overlapping edges of first and second synthetic turf pieces having a backing joined together; the backing without seaming cloth/tape material can be coated with an adhesive/glue, volatile solvent or heat activated material or not and reinforcement fastener elements inserted through both the backing of the synthetic turf material.
1. A reinforced seam structure comprising:
abutted together edges of a first synthetic turf piece and a second synthetic turf piece joined together, each piece having a backing wherein said backing has a topside and an underside;
a seaming cloth/tape material having a topside and an underside positioned beneath the abutted edges of said first and second synthetic turf pieces wherein said abutted edges are pressed down into an adhesive applied to the seaming cloth/tape material; and
reinforcement fastener elements inserted through the backings of said first and second synthetic turf pieces, through the adhesive and the seaming/cloth tape material,
wherein the reinforcement fastener elements comprise a vertical rod-shaped flexible filament portion connecting horizontal cross bars at the top end and bottom end thereof.
2. The reinforced seam structure of claim 1 , wherein the reinforcement fastener elements range in length from ⅛ up to 2.5 inches, wherein the lengths represent the distance of the rod shaped flexible filament portion located between the cross bars, maintaining the fastened items the backing and seaming material/tape within a range of 3/64 inches to 2 and 7/16 inches.
3. The reinforced seam structure of claim 1 , wherein the reinforcement fastener elements are inserted through both the turf backing, the adhesive and the seaming/cloth tape material such that the rod shaped portion vertically passes through both the turf backing material and the seaming/cloth tape material and the horizontal cross bar at the top end of the filament is on the topside of the turf backing material and the horizontal cross bar at the bottom end is at the underside of the seaming/cloth tape material
4. The reinforced seam structure of claim 1 , wherein the reinforcement fastener elements have a tensile strength of from 2 lbs to 25 lbs.
5. A method for forming a reinforced seam structure according to claim 1 , said method comprising:
a) abutting the edges of synthetic turf pieces to be joined together, each piece having a backing wherein said backing has a topside and an underside;
b) positioning a seaming/cloth tape material beneath the abutted edges of said synthetic turf pieces;
c) applying an adhesive material for said backing on said seaming/cloth tape material beneath the abutted edges of said synthetic turf pieces;
d) calibrating spacing between the backing of the artificial turf pieces providing maximum contact between both backings of the synthetic turf pieces;
e) inserting at least one reinforcement fastener element through both the backings of the synthetic turf pieces the adhesive material and the seaming cloth tape material;
f) allowing the adhesive material to cure and set up while said abutted edges are in contact with said seaming cloth tape material,
wherein the at least one reinforcement fastener element comprises a vertical rod-shaped flexible filament portion connecting horizontal cross bars at the top end and bottom end thereof.
6. The method of claim 5 , wherein the at least one reinforcement fastener element is inserted through the backing of the synthetic turf pieces, adhesive and the seaming cloth tape material such that the rod-shaped flexible filament portion vertically passes through the backings of the synthetic turf pieces, the adhesive material and the seaming/cloth tape material and the horizontal cross bar at the top end of the filament is on the topside of the backing of synthetic turf pieces and the horizontal cross bar at the bottom end of the filament is at the underside of the seaming/cloth tape material.
7. The method of claim 5 , further comprising applying a force along at least a portion of the abutted edges of the synthetic turf pieces to thereby urge said abutted edges into contact with the adhesive on the seaming/cloth tape material.
8. The method of claim 5 , wherein the at least one reinforcement fastener element has a tensile strength of from 2 lbs to 25 lbs.
