DETAILED DESCRIPTION OF EMBODIMENTS

(9) Referring to FIGS. 1 and 2, one embodiment of seaming tape 10 is illustrated. In this embodiment, seaming tape 10 can comprise mesh tape portion 12 overlaid on blocking tape portion 14. In one embodiment, mesh tape portion 12 can be comprised of fiberglass mesh, such as the type used in the installation and repair of stucco although it is obvious to those skilled in the art that any suitable material for joining pieces of floor-covering together can be used for mesh tape portion 12, such as plastic mesh materials (including polypropylene and nylon mesh or webbing), textile materials (including fabrics and the like) or any other suitable materials known for reinforcing the seams between pieces of floor-covering materials.

(10) In a representative embodiment, mesh tape portion 12 can have a width in the range of 2 to 3 although it is obvious to those skilled in the art that mesh tape portion 12 can be of any suitable width for joining adjacent pieces of floor-covering, whether that floor-covering is carpet or of resilient flooring material. In a further embodiment, mesh tape portion 12 can comprise a plurality of openings 13. In a representative embodiment, openings 13 are approximately square although any suitable sized opening for receiving seaming adhesive can be used. In a further embodiment, mesh tape portion 12 can comprise a pressure-sensitive adhesive.

(11) In yet another embodiment, blocking tape portion 14 can be comprised of coated paper that can be disposed on mesh tape portion 12. It is obvious to those skilled in the art that other materials can be used for blocking tape portion 14, which can include plastic tape and/or fabric and other suitable textile materials that can provide a barrier between a floor and mesh tape portion 12. In a representative embodiment, blocking tape portion 14 can be approximately 1 to 1 wide although any suitable width can be used, as obvious to those skilled in the art, that is narrower in width than the width of mesh tape portion 12.

(12) In one embodiment, blocking tape portion 14 can be held in place to mesh tape portion 12 by the pressure-sensitive adhesive disposed on mesh tape portion 12. It is obvious to those skilled in the art that seaming tape 10, when manufactured in volume, can be manufactured using mesh tape portion 12 that is not treated with a pressure-sensitive adhesive, and by applying a suitable adhesive between mesh tape portion 12 and blocking tape portion 14 and then sandwiching the tape portions together thereby bonding them together.

(13) Referring to FIG. 3, an exploded view of seaming tape 10 is shown in the seaming of two adjacent pieces of carpet 16 on floor 20. In this representative embodiment, seaming tape 10 is configured with mesh tape portion 12 facing up towards carpet 16, and blocking tape portion 14 facing down towards floor 20. Floor adhesive 22, as well known to those skilled in the art, is placed on floor 20. Seaming tape 10 is placed on top of floor adhesive 22 along the line where the adjacent pieces of carpet 16 will join together along seam 17. Seaming adhesive 18 can be applied between and beneath the edges of carpet 16 being joined together using a seaming adhesive applicator tip (not shown) as well known by those skilled in the art. Openings 13 in mesh tape portion 12 receive seaming adhesive 18 dispensed between the pieces of carpet 16 and aid in distributing the hot glue to carpet 16. Blocking portion 14, disposed beneath mesh tape portion 12 and above floor adhesive 22 acts as a barrier with at least two functions. A first function of blocking tape portion 14 is to prevent hot glue 18 from passing through openings 13 of mesh tape portion 12, thereby preventing full adhesion of seaming adhesive 18 to pieces of carpet 16. A second function of blocking tape portion 14 is to prevent the intermingling of floor adhesive 22 with seaming adhesive 18 that can prevent seaming adhesive 18 from fully bonding pieces of carpet 16 to each other.

(14) Referring to FIG. 4, an alternate embodiment of seaming tape 10 is shown. In this embodiment, seaming tape 10 can further comprise center line 24 disposed on a top surface thereof. In some embodiments, center line 24 can be disposed along the length of seaming tape 10 substantially in the middle or centered between edges 15 of seaming tape 10. Center line 24 can provide means to visually guide an installer to place seaming tape 10 substantially centered underneath the gap between two pieces of floor-covering to be joined or seamed together. In some embodiments, center line 24 can be a solid line. In other embodiments, center line 24 can be a dashed or dotted line, or combinations thereof. In further embodiments, center line 24 can be a line of printed text, such as the manufacturer's name, the lot number or production run number, the date of manufacture, or any other text, or any other visual marking disposed substantially down the center of seaming tape 10 between edges 15 wherein center line 10 that can function as a visual guide to indicate the center of seaming tape 10.

(15) In some embodiments, center line 24 can comprise a colored thread disposed in mesh tape portion 12. In other embodiments, center line 24 can be printed on blocking tape portion 14. In further embodiments, center line 24 can comprise painting or marking a line of paint or ink on mesh tape portion 12 or on blocking tape portion 14. In further embodiments, center line 24 can comprise a colored tape disposed on mesh tape portion 12 or between mesh tape portion 12 and blocking tape portion 14.

(16) Referring to FIG. 5, marking tool 26 is shown, which can be used in the installation of seaming tape 10 when seaming pieces of floor-covering together. In some embodiments, marking tool 26 can comprise flat substrate 27 and stop 28 disposed on top thereof, thereby forming floor-covering side 30 and marking side 32 further comprising marking edge 34.

(17) Referring to FIG. 6, marking tool 26 is shown being used with piece of carpet 16. Floor-covering side 30 of marking tool 26 can be placed underneath carpet 16 wherein carpet 16 abuts stop 28. In some embodiments, the dimension of marking side 32 can be selected wherein the distance X, as shown in FIG. 6, is approximately the same as the lateral distance between center line 24 and edge 15 of seaming tape 10, as shown in FIG. 4.

(18) When installing seaming tape 10 between abutting side-by-side layers of planar material, such as floor-coverings, carpet, etc., an installer can first place or install one of the side-by-side layers of the planar material. While the planar material is typically installed on a horizontal surface such as a floor or stair treads or other horizontal surfaces as obvious to those skilled in the art, the planar material can also be installed on non-horizontal surfaces as obvious to those skilled in the art. Upon installing the first piece of planar material to be seamed, such as carpet 16 shown in FIG. 6, the installer can run marking tool 26 along an abutting edge of carpet 16 while using marking pen or pencil 36 to draw a guide line along marking edge 34 on the floor adjacent to the abutting edge of carpet 16. Once a line has been drawn on an installation surface (the floor in the illustrated example shown in FIG. 6) along the edge of carpet 16, the drawn line can provide a visual guide to the installer as to where edge 15 of seaming tape 10 should lay underneath carpet 16 when seaming carpet 16 to another piece of carpet. In so doing, center line 24 should lay along the edge of carpet 16 where the seam is to be made to provide a visual guide to the installer that seaming tape 10 is properly positioned underneath carpet 16.

(19) Referring to FIG. 7, an alternate embodiment of a marking tool is shown for drawing a guide line. In some embodiments, marking tool 38 can comprise cylindrical portion 40 disposed on top of flange portion 42, with marking pen opening 44 extending therethrough. In some embodiments, the diameter of cylindrical portion 40 can be selected wherein its radius can be approximately distance X as shown in FIG. 6.

(20) Referring to FIG. 8, marking tool 38 is shown in use to mark guide line 46. Flange portion 42 can be placed under carpet 48 until cylindrical portion 40 abuts edge 50 of carpet 48. Marking pen 36 can be inserted through opening 44 to mark guide line 46 on the floor. An installer can then move marking tool 38 down along edge 50 whereby cylindrical portion 42 rolls along edge 50 resulting in marking pen 36 marking guide line 46 on the floor substantially parallel to edge 50.

(21) In some embodiments, a kit is provided for seaming abutting side-by-side layers of planar material. The kit can comprise a length of seaming tape 10. In other embodiments, the kit can comprise a set of instructions explaining how seaming tape 10 can be used to seam abutting side-by-side layers of planar material. In further embodiments, the kit can comprise marking tool 26. In other embodiments, the kit can comprise marking tool 38. In yet further embodiments, the kit can further comprise a marking pen or pencil for use with marking tool 26 or marking tool 38.
