を矯正している。Here, in order to correct the slight meandering of the hoop-shaped porous core to the left and right that occurs when applying paste, the hoop-shaped porous core is wrapped around one or two rollers, and the roller is moved to the hoop-shaped porous core. The meandering of the hoop-shaped porous core is corrected by a method (end pivot or center pivot) in which the core moves linearly or circularly in a direction perpendicular to the traveling direction of the core.

蛇行量の解消、減少には限度があった。In this method, the position detection unit of the hoop-shaped porous core body and the correction device unit have a positional relationship in front and rear or up and down with respect to the paste application unit (application position). The position where the paste is applied to the porous core and the position where the paste is corrected are different, and a time lag occurs in the meandering correction of the hoop-shaped porous core,
There was a limit to the elimination and reduction of the meandering amount.

焼結多孔体が得られないという問題があった。In addition, since one or two rollers on which the hoop-shaped porous core of the straightening device is wrapped are forcibly moved by a motor or a cylinder, the hoop-shaped porous core is twisted and permanent deformation occurs in the porous core. There is a problem that a balanced sintered porous body cannot be obtained.

幅に向上できる。FIG. 2 shows a paste coating apparatus for obtaining a constant paste coating thickness in this manufacturing apparatus. FIG. 2 is an explanatory view of the paste coating apparatus of the present invention. As is clear from the figure, the hoop-shaped porous core 2 and the doctor knife 4 are different from each other.
A positioning jig 10 composed of a U-shaped cross-section frame integrally provided on the left and right sides of the core is set equal to the width of the porous core body, and is inserted into the left and right ends of the core body inside the respective frame bodies, and The body is slidably provided with the core so that the body can pass smoothly from below to above. Therefore, the jig 10 also follows the slight meandering of the core 2, and a fixed positional relationship that the doctor knife integrally mounted with the jig 10 moves to the left and right as the core meanders is always maintained. In order to make the doctor knife immediately follow the meandering of the porous core, the sliding shaft
A follow-up device 13 composed of the slide bearing 11 and the sliding bearing portion 12 is preferably provided on the doctor knife, so that the follow-up performance of the doctor knife 4, which follows the meandering of the core body 2 sensitively, can be greatly improved.

方向への力より小さいことは言うまでもない。The paste coating device of the present invention is adapted to follow the hoop-shaped porous core by a force in a direction (left and right direction) perpendicular to the traveling direction of the porous core when the hoop-shaped porous core slightly meanders left and right. Needless to say, the force (resistance) at the time of starting is smaller than the force in the direction perpendicular to the porous core.

This realizes the state, and the misalignment of the porous core with the doctor knife due to the meandering of the porous core is completely eliminated as compared to the conventional core meandering correction device. Since no distortion occurs, a balanced sintered porous body can be obtained.
