    • The manufacturing method of the plugged honeycomb structure for DPF wherein a plugging depth thereof can easily be made uniformly and briefly at low costs. In the method for manufacturing a plugged honeycomb structure having a plugging portion formed in one opening end portion of each of predetermined cells of a cylindrical honeycomb structure including a plurality of cells partitioned and formed into a honeycomb shape by porous partition walls to form fluid passages, holes 3 of a perforated elastic porous member 2 are impregnated beforehand with a slurried plugging material 5, and the elastic porous member 2 is pressed on an end surface of the honeycomb structure 6 to thereby fill the slurried plugging material 5 filled into the holes of the elastic porous member 2 into cell 7 passages of the honeycomb structure 6 to form the plugging portions 7a.
    • 用于DPF的堵塞蜂窝结构体的制造方法,其中其堵塞深度可以容易地以低成本均匀和短暂地制成。 在具有形成在圆筒形蜂窝结构体的每个预定单元的一个开口端部中的封孔部的封孔部的制造方法中,所述圆筒状蜂窝结构体具有多个分隔壁分隔成蜂窝状的多个单元,形成流体通路, 穿孔弹性多孔构件2的孔3预先用浆状堵塞材料5浸渍,并且弹性多孔构件2被压在蜂窝结构体6的端面上,从而填充填充到蜂窝结构体6的孔中的浆状堵塞材料5 弹性多孔构件2插入到蜂窝结构体6的单元7通道中,以形成堵塞部7a。
