A circular through-hole is provided in the thickness direction of the part, and counter-bore screw holes are provided at intervals around the through-hole on the surface facing the cloth and in the lower part of the holding plate. Place the above-mentioned presser plate around the stock solution supply port on each opposing side of a pair of hazel cloths interposed between the hazel cloths, and insert a countersunk screw through the hazel cloth and the presser plate from the haze cloth side. Make sure that the threaded portions of the presser plates protrude from the opposing surfaces of the presser plates, and that the fabric is slightly inserted into each screw threading hole of each presser plate, and that the fabrics at the attachment parts of the presser plates do not loosen. Attach each presser plate to the cloth so that the through hole of each presser plate fits into the stock solution supply port of each cloth, and then attach the threaded portions of the countersunk screws that are attached to both pressers and face each other. are connected to each other with a nut to form a gap at a constant interval of the same size as the thickness of the nut between the opposing presser plates. Functions and Effects of the Invention According to the present invention, as configured as described above, there is no restriction on the liquid supply path for supplying the raw liquid into the transfer chamber, and there is no restriction on the liquid supply path for supplying the raw liquid into the transfer chamber, and there is no limit to the liquid supply path from the through hole of the presser material to the surrounding area, such as the top, bottom, right, left, etc. It is possible to freely and smoothly supply and integrate the stock solution in both directions, increasing the speed at which the stock solution is supplied into the reaction chamber and improving production efficiency, as well as easily removing the stock solution remaining between both presser members. Can be washed.

In addition, since the nut is rotated, the connection between both holding plates can be easily released by rotating the countersunk screw, and each released stock solution supply plate is fixed to each furnace cloth by the countersunk screw. Since the retaining plate remains in place, it is easy to disassemble and clean the retaining plate, and by removing the blood screws, each stock solution supply plate can be easily removed from each furnace cloth, and the retaining plate can be easily repaired.
