Abstract
The present invention relates to a thermal pressure welding apparatus for the waist of incontinent pants and training pants and a thermal pressure welding method. The apparatus can thermal pressure weld the waist of incontinent pants and training pants consists of multiple layers of non-woven fabric in a fast, accurate and secure manner. An upper synchronous transmission mechanism and a lower synchronous transmission mechanism are disposed vertically opposed, by means of a shaft, on a side of a vertical frame. The upper synchronous transmission surface of the upper synchronous transmission mechanism and the synchronous transmission surface of the lower synchronous transmission mechanism are opposed. A plurality of toothed pressing blocks are spacedly opposed on the upper synchronous transmission surface and the lower synchronous transmission surface respectively. An electrothermal tube inside the toothed pressing block is connected to supply lines in a conductive ring through extendable wires and wiring flanges, which conductive ring is rotated synchronously with the upper synchronous transmission mechanism and the lower synchronous transmission mechanism. The plane rails moving up…
