    • Pipe coating apparatus including a concrete applicator station, a pipe conveyor adapted to longitudinally advance and axially rotate a section of pipe alongside the concrete applicator station, and an overhead container adapted to receive and dispense a supply of mixed concrete to the concrete applicator station. The concrete applicator station includes one or a plurality of concrete applicators, each concrete applicator being adapted to extrude a layer of concrete onto a carrier band, and to horizontally convey the layer of concrete on the carrier band to the underside of the pipe to form a continuous helical wrap of the layer of concrete on the carrier band around the pipe as the pipe is advanced and rotated, and in the case of the plurality of concrete applicators, each concrete applicator being laterally spaced one from another alongside the pipe such that the helical wrap from a first of the plurality of concrete applicators is successively covered by the helical wrap from each of an adjacent concrete applicator of the plurality of concrete applicators.

    • An object of the present invention is to provide a manufacturing method of a honeycomb structural body which makes the profile of a cross section perpendicular to the length direction thereof less likely to generate dispersion, and also makes the thickness of its sealing material layer thinner, and a sealing material that is suitably used in the manufacturing method of the honeycomb structural body. According to the present invention, the manufacturing method of a honeycomb structural body with a sealing material layer formed on the peripheral portion of a pillar-shaped porous honeycomb member includes a sealing material applying step of applying a paste-like sealing material, which is a raw material of the sealing material layer, onto a circumferential face of the pillar-shaped porous honeycomb member, and a scraping step of fitting a ring-shaped scraper, which can be brought into contact with the circumferential face of the pillar-shaped porous honeycomb member so as to slide thereon, to the pillar-shaped porous honeycomb member and moving said ring-shaped scraper in the length direction, thereby expanding the paste-like sealing material applied onto the circumferential face of the pillar-shaped porous honeycomb member so as to spread over the entire circumferential face of the pillar-shaped porous honeycomb member.
    • 本发明的目的是提供一种蜂窝状结构体的制造方法,其使与其长度方向垂直的截面的轮廓不太可能产生分散,并且还使得其密封材料层的厚度更薄,以及 适用于蜂窝结构体的制造方法的密封材料。 根据本发明,在柱状多孔质蜂窝构件的周缘部形成有密封材料层的蜂窝结构体的制造方法包括:施加膏状密封材料的密封材料施加工序,所述膏状密封材料为 密封材料层的原料在柱状多孔质蜂窝构件的周面上,以及与可与柱状多孔蜂窝体的周面接触的环状刮刀的刮削工序, 将其滑动到柱状多孔蜂窝构件上并沿长度方向移动所述环形刮刀,从而使施加到柱状多孔蜂窝构件的圆周面上的糊状密封材料膨胀,从而 分散在柱状多孔质蜂窝构件的整个圆周面上。
