Title:
APPARATUS AND METHOD FOR PRODUCING STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2022/196806
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an apparatus and a method whereby it becomes possible to reduce the difference between the length of a slurry layer formed in an inside part of a wall-flow-type substrate when observed in the direction of diameter of the wall-flow-type substrate and the length of the slurry layer formed in an outside part of the wall-flow-type substrate when observed in the direction of diameter of the wall-flow-type substrate. In the apparatus and the method, when a slurry M supplied to a first edge surface (T1) of a porous substrate (1) is absorbed from the side of a second edge surface (T2) of the porous substrate (1), a flow straightening member (40) that covers a center region (T12, T22) of either one of the first edge surface (T1) or the second edge surface (T2) and exposes at least a portion of an outer edge region (T11, T21) of the edge surface is provided on the side of the first edge surface (T1) or the second edge surface (T2).
