Abstract
A system and method for forming a seam between at least first and possibly second pieces of material used to form an inflatable product utilizes at least a first and potentially a second seam forming members that are attached to an inside wall of a piece of product material that comprises the inflatable product proximate each end. The inflatable product is comprised of one or more pieces of product material and one or more seam forming members located at any location where a seam is necessary. A first portion of the seam forming member attaches to a first edge of a first piece of product material and a second portion of the seam forming member attaches proximate a second edge of the first piece of product material. The seal forming can be accomplished by radio frequency, ultrasonic, heat or other types of welding, and adhesive or chemical based bonding.
