Currently, when manufacturing inflatable products using a wire drawstring, a wire drawstring group (including a plurality of parallel wire bodies and a plurality of pressing strips combined with the wire bodies) is generally directly produced, and then the wire drawstring group is cut (the pressing strips are cut open) to obtain a wire drawstring. The wire drawstring obtained by cutting is welded by a welding device to simultaneously melt the two pressing strips of the wire drawstring with the upper sheet and the lower sheet.
