  • Patent number: 7481250
    Abstract: A fabric for a horizontal belt filter includes a two-layer structure in which an upper-surface-side weft forming an upper-surface-side layer and a running-face-side weft forming a running-face-side layer are woven together by a warp. An upper-surface-side surface of the fabric includes a warp long crimp portion of a warp which passes over four or more continuous upper-surface-side wefts; and a warp latent portion which passes under one to four upper-surface-side wefts. At least a part of the warp latent portion passes under one or two running-face-side wefts to weave together the upper-surface-side layer and the running-face-side layer. The warp long crimp is formed on the upper-surface-side surface, and a weft long crimp is formed on a running-face-side surface. The fabric exhibits a good peeling property of a treated matter and which is superior in a cleaning property, rigidity, running stability, and wear resistance.

  • Patent number: 5946766
    Abstract: The invention provides a cleaning method for removing dirt on an industrial belt and a cleaning belt used in the same. A cleaning belt having through-holes is provided onto an industrial belt. The cleaning belt comprises structural unit pieces in parallel to one another in a lengthwise direction. Each of the unit pieces is loosely interconnected and has a play such that the unit piece can move. The movement gives vibration onto the industrial belt when the cleaning belt is brought in contact with the surface of a running industrial belt. Then dirt on the industrial belt is removed through the through-holes.

  • Patent number: 5274893
    Abstract: Method for manufacturing a non-woven fabric with irregular patterns by using a belt having projections for providing irregular patterns on the non-woven fabric and applying highly pressurized water and hot air onto a fiber assembly placed on and carried by the belt in order to press the fiber assembly to the belt and entangle the fiber of the fiber assembly.
