Abstract:
1. A honeycomb filter production apparatus used for producing a honeycomb filter, the apparatus comprising: a workpiece securing section for securing a base of a honeycomb filter; a powder transfer section disposed on one side of the workpiece securing section, and transfers a powder together with an air current by utilizing pressurized gas, wherein the powder transfer section includes an ejector as a powder-dispersing means; an introduction section provided between the powder transfer section and the workpiece securing section, wherein the powder transferred from the powder transfer section together with the air current is mixed with air in the introduction section, wherein the introduction section has a speed adjusting means for adjusting the speed by swirling the powder transferred by the air current from the powder transfer section and introduced into the base of the honeycomb filter secured by the workpiece securing section when the apparatus is used, wherein the introduction section has an open space formed between the powder transfer section and the workpiece securing section, such that a flow rate of the air current that flows through the powder transfer section and a flow rate of the powder with air current passed into cells of the honeycomb filter are independently controlled; a suction section disposed on the other side of the workpiece securing section, for sucking the gas that has passed through the base secured by the workpiece securing section by reducing pressure on the other side of the workpiece securing section as compared with the one side of the workpiece securing section using suction means.
