Abstract
A forming belt and/or a transfer belt which are belts for a forming part of an apparatus for manufacturing a construction material, prevent stains caused by entry of raw material particles and has excellent rigidity and cleanability.
Claims12
A woven net forming belt suitable for use in manufacturing a construction material comprising:
- monofilament yarn as a weft on a traveling surface side of said belt;
- yarn in which a dehydrating space is formed between bundles of plain yarn as a weft on a forming surface side of said belt;
- and
- monofilament or monofilament twist yarn as a warp, wherein said belt includes a plurality of weft layers and at least one warp layer.
A transfer belt for manufacturing a construction material capable of receiving wet materials formed by a forming part and joining at least two of said construction materials together sequentially, said belt comprising a woven net formed by using i) monofilament yarn as a weft on a traveling surface side of said belt, ii) yarn having dehydrating space formed between bundles of plain yarn as a weft on a forming surface side of said belt, and iii) monofilament or monofilament twist yarn as a warp, and wherein a plurality of weft layers and at least single warp layer are arranged in said woven net.
A woven net belt, comprising:
- at least one belt surface comprising an aggregate of fibers,
- an intermediate layer, and
- a woven network structure which as a whole makes up for a remainder of said belt, wherein wefts are interwoven with warps and warps are interwoven with wefts in a cycle,
- wherein said intermediate layer is a weft layer selected from the group consisting of spun yarn, multifilament yarn, rasing yarn, monofilament twist yarn, chenille yarn, filament processed yarn, yarn formed by winding spun yarn around a monofilament core, yarn formed by winding multifilament yarn around a monofilament core and yarn formed by twisting at least two yarns together that is arranged between a weft layer on a traveling surface side of the belt and a weft layer on a forming surface side of the belt.
A method for preparing a woven net forming belt, comprising:
- providing a woven network structure wherein wefts are interwoven with warps and warps are interwoven with wefts in a cycle, that is attached to an intermediate layer, that is attached to at least one surface layer comprising an aggregate of fibers,
- wherein said intermediate layer is a weft layer selected from the group consisting of spun yarn, multifilament yarn, rasing yarn, monofilament twist yarn, chenille yarn, filament processed yarn, yarn formed by winding spun yarn around a monofilament core, yarn formed by winding multifilament yarn around a monofilament core and yarn formed by twisting at least two yarns together that is arranged between a weft layer on a traveling surface side of the belt and a weft layer on a forming surface side of the belt.
A woven net belt, comprising:
- at least one belt surface comprising an aggregate of fibers,
- an intermediate layer, and
- a woven network structure which as a whole makes up for a remainder of said belt, wherein wefts are interwoven with warps and warps are interwoven with wefts in a cycle,
- wherein said intermediate layer is a weft layer made of monofilament yarn and selected from the group consisting of monofilament spun yarn, multifilament yarn, rasing yarn, monofilament twist yarn, chenille yarn, filament processed yarn, yarn formed by winding spun yarn around a monofilament core, yarn formed by winding multifilament yarn around a monofilament core and yarn formed by twisting at least two yarns together that is arranged between a weft layer on a traveling surface side of the belt and a weft layer on a forming surface side of the belt.
A method for preparing a woven net forming belt, comprising:
- providing a woven network structure wherein wefts are interwoven with warps and warps are interwoven with wefts in a cycle, that is attached to an intermediate layer, that is attached to at least one surface layer comprising an aggregate of fibers,
- wherein said intermediate layer is a weft layer made of monofilament yarn and selected from the group consisting of monofilament spun yarn, multifilament yarn, rasing yarn, monofilament twist yarn, chenille yarn, filament processed yarn, yarn formed by winding spun yarn around a monofilament core, yarn formed by winding multifilament yarn around a monofilament core and yarn formed by twisting at least two yarns together that is arranged between a weft layer on a traveling surface side of the belt and a weft layer on a forming surface side of the belt.
