Abstract: There is disclosed cutting means of a honeycomb dried body in which cracks are not easily generated in the honeycomb dried body, even when a grindstone continues to be used for a long period of time, a cutting speed is raised and a cutting object is a honeycomb dried body having a large diameter. There is provided a cutting method of a honeycomb dried body to cut the honeycomb dried body while applying a force Pm which resists a thrust force Pt required for the cutting and a weight Pw of a cutoff section, to a portion which becomes the cutoff section.

Abstract: The drying method performs drying the honeycomb formed article by such an arrangement that superheated steam or mixed gas of steam and hot air, temperature and humidity of which is regulated so that wet-bulb temperature thereof becomes 70° C. or higher, is made to pass through the cells of the honeycomb formed article. The drying apparatus includes a steam supply unit that supplies the superheated steam, a buffer chamber that aligns the superheated steam supplied from the steam supply unit, an upper chamber disposed above the buffer chamber to locate the honeycomb formed article, and a hood unit that recovers the superheated steam which has passed through the honeycomb formed article.

Abstract: There is disclosed a conveyer and a conveying method that enable conveying a lengthy honeycomb formed article extruded at a high speed with a simple apparatus without causing cracks and deformation. The conveyer of a honeycomb formed article includes a plurality of lengthy cradles that are sequentially supplied and then sequentially support and convey the honeycomb formed article, and a fixed support that is fixed so as to extend from the extruder to a supply position of the lengthy cradles, supports the honeycomb formed article just after being extruded, and conveys it to one of the lengthy cradles, and the fixed support is an air float having a supporting face and a plurality of air ejection pores formed on the supporting face that conveys the honeycomb formed article by feeding air from the air ejection pores.

Abstract: A method of drying a honeycomb formed article, in which the honeycomb formed article can be dried in a short time while prohibiting occurrence of defects such as deformation, breakage and the like. There is provided a drying method of an unfired honeycomb formed article including raw material composition containing ceramics raw material, water, and binder, and having a plurality of cells, the cells being separated by partition walls to be passage of fluid, and electromagnetic wave drying is performed to dry the honeycomb formed article after the honeycomb formed article is preheated by steam.

Abstract: There is disclosed a conveyer and a conveying method that enable conveying a lengthy honeycomb formed article extruded at a high speed with a simple apparatus without causing cracks and deformation. The conveyer of a honeycomb formed article includes a plurality of lengthy cradles 3a that are sequentially supplied and then sequentially support and convey the honeycomb formed article 5, and a fixed support that is fixed so as to extend from the extruder 2 to a supply position of the lengthy cradles 3a, supports the honeycomb formed article 5 just after being extruded, and conveys it to one of the lengthy cradles 3a, and the fixed support is an air float 4 having a supporting face 14 and a plurality of air ejection pores 24 formed on the supporting face that conveys the honeycomb formed article 5 by feeding air from the air ejection pores 24.
