  • Thermal pressure welding apparatus and thermal pressure welding method for waists of incontinent pants and training pants
    Patent number: 8709182
    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.
