Claim Text:
1. A welding system for welding two piece of fabric comprising: a fabric welding machine; a conveyer table adapted to feed an non-welded sidewall fabric to the welding machine at a first speed; a turntable adapted to rotate to feed an non-welded second fabric to the welding machine at the first speed so that an edge of the second fabric overlaps an edge of the sidewall fabric; wherein the welding machine is stationary and is configured to weld the non-welded sidewall fabric to the non-welded second fabric using a first welding temperature as the non-welded sidewall fabric and the non-welded second fabric past through the welding machine at the first speed; a main roller in the welding machine adapted to the roll sidewall fabric and the second fabric that have been welded together as a welded fabric through the welding machine at the first speed; a controller logic configured to detect a single request for a change of a parameter at a user interface, and wherein when the controller detects the single request for the change of the parameter the controller is configured to change at least one of the group of: the first welding temperature to a second welding temperature, change the speed of the turntable so that the second fabric is delivered to the welding machine at a second speed that is different than the first speed, and change the speed of the conveyer table so that the first fabric is delivered to the welding machine at the second speed; and a fabric feed assembly adapted to feed the non-welded sidewall fabric to the conveyer table, wherein the fabric feed assembly comprises: wherein the fixed frame further comprises an alignment detection device configured to determine if an edge of the non-welded sidewall fabric is aligned with a predetermined location as the non-welded sidewall fabric is fed to the conveyer table and wherein an alignment adjustment logic is configured to cause the movable platform to move to align the edge of the non-welded sidewall fabric with the predetermined location when the edge of the non-welded sidewall fabric is not aligned with the predetermined location.
