Abstract

A method for applying a thermoreactive seam tape to a seam is provided. The thermoreactive seam tape may be positioned adjacent to the seam, which may include a first fabric surface and an adjacent second fabric surface. The thermoreactive seam tape may include an interior planar surface that engages both the first fabric surface and the second fabric surface of the seam. The thermoreactive seam tape may further include an exterior surface opposite the interior surface, where the exterior surface is substantially non-planar with respect to the interior planar surface along a length of the thermoreactive seam tape. Heat and pressure may be applied to the thermoreactive seam tape, wherein the heat and the pressure facilitate adhesion of the thermoreactive seam tape to the first fabric surface and the second fabric surface of the seam.

First claim

The invention claimed is:

1. A method for applying an extruded, single-layer, thermoreactive seam tape to a seam, the seam comprising a first fabric surface and an adjacent second fabric surface, the method comprising:
positioning the extruded, single-layer, thermoreactive seam tape adjacent to the seam, the extruded, single-layer, thermoreactive seam tape comprising:
an interior planar surface that engages both the first fabric surface and the second fabric surface of the seam; and
an exterior surface opposite the interior surface, the exterior surface being a continually non-planar surface with respect to the interior planar surface along a length of the extruded, single-layer, thermoreactive seam tape, the exterior surface being an outwardly facing concave surface extending between a first side and a second side of the thermoreactive seam tape; and
applying heat and pressure to the extruded, single-layer, thermoreactive seam tape, wherein the heat and the pressure facilitate adhesion of the extruded, single-layer, thermoreactive seam tape to the first fabric surface and the second fabric surface of the seam.

2. The method of claim 1 , wherein the pressure is applied to the extruded, single-layer, thermoreactive seam tape in a direction that is perpendicular to the exterior surface.

3. The method of claim 1 , wherein a heated seam tape roller is used to apply the heat and the pressure to the extruded, single-layer, thermoreactive seam tape.

4. A method for applying a thermoreactive seam tape to a seam, the seam comprising a first fabric surface and an adjacent second fabric surface, the method comprising:
positioning the thermoreactive seam tape adjacent to the seam, the thermoreactive seam tape comprising:
an interior planar surface that engages both the first fabric surface and the second fabric surface of the seam; and
an exterior surface opposite the interior surface, the exterior surface being a continually non-planar surface with respect to the interior planar surface along a length of the thermoreactive seam tape, the exterior surface being an outwardly facing concave surface extending between a first side and a second side of the thermoreactive seam tape;
positioning a heated seam tape roller adjacent to the exterior surface of the thermoreactive seam tape; and
rolling the heated seam tape roller along the length of the thermoreactive seam tape in order to facilitate adhesion of the thermoreactive seam tape to the first fabric surface and the second fabric surface of the seam.

5. The method of claim 4 , wherein the heated seam tape roller engages the exterior surface of the thermoreactive seam tape.

6. The method of claim 4 , wherein the heated seam tape roller is used to apply heat and pressure to the thermoreactive seam tape.

7. The method of claim 6 , wherein the heated seam tape roller is used to apply the pressure to the thermoreactive seam tape in a direction that is perpendicular to the exterior surface.

8. The method of claim 6 , wherein the heat and the pressure facilitate the adhesion of the thermoreactive seam tape to the first fabric surface and the second fabric surface.

9. The method of claim 8 , wherein the heat causes the interior surface to melt and adhere to the first fabric surface and the second fabric surface along the length of the thermoreactive seam tape.

10. The method of claim 9 , wherein the exterior surface is less thermoreactive than the interior surface.

11. The method of claim 10 , wherein the heat does not cause the exterior surface to melt.

12. A method for applying a thermoreactive seam tape to a seam, the seam comprising a first fabric surface and an adjacent second fabric surface, the method comprising:
positioning the thermoreactive seam tape directly adjacent to the seam, the thermoreactive seam tape comprising:
an interior planar surface that engages both the first fabric surface and the second fabric surface of the seam; and
an exterior surface opposite the interior planar surface, the exterior surface being a continually non-planar surface with respect to the interior planar surface along a length of the thermoreactive seam tape, the length extending from a first end to a second end of the thermoreactive seam tape, the exterior surface being an outwardly facing concave surface extending between a first side and a second side of the thermoreactive seam tape;
positioning a heated seam tape roller directly adjacent to the exterior surface of the thermoreactive seam tape at the first end of the thermoreactive seam tape; and
rolling the heated seam tape roller along the length of the thermoreactive seam tape toward the second end of the thermoreactive seam tape in order to facilitate adhesion of the thermoreactive seam tape to the first fabric surface and the second fabric surface of the seam.

13. The method of claim 12 , further comprising applying tension to at least one of the thermoreactive seam tape, the first fabric surface, or the second fabric surface in order to prevent wrinkling.
