Abstract: A method is disclosed for forming a substantially flush joint or coupling between two profile wall thermoplastic pipes. The method comprises removing substantially all of the helical rib and inner wall of a first pipe for a distance from an end of the first pipe and removing a portion of the helical rib for a distance from an end of a second pipe. By so doing, the outer wall of the second pipe can be deflected radially inward and the end of the second pipe can thereby be coupled with the first pipe by overlapping the outer walls adjacent the ends of the first and second pipes, with the outer wall of the first pipe being on the exterior. When overlapped, the second walls of both the pipes can then be fused together. Alternatively, the outer wall of the first pipe can be removed rather than the inner wall, and the inner wall of the second pipe deflected radially outward such that the inner wall of the second pipe can be positioned around the inner wall of the first pipe and fused thereto.

Abstract: A method is provided for joining two pieces of elastomeric fabric together without the need for sewing or stitching the seam. This is accomplished by cutting a first piece of elastomeric fabric to form a first edge having a predetermined first geometric pattern. Similarly, a second piece of elastomeric fabric is cut to form a second edge having a predetermined second geometric pattern which corresponds with the first geometric pattern. The lateral surfaces of the geometrically patterned first and second edges then have a bonding agent applied prior to mating the patterned edges to one another to create an intersecting seam between the first and second pieces of the elastomeric fabric. The intersecting seam is immobilized to allow the bonding agent to set. Tape may be placed on one or both sides of the seam for additional strengthening.
