Method for producing honeycomb structure
A method for producing a honeycomb structure including producing an unfired pillar shaped honeycomb body; placing the unfired pillar shaped honeycomb body on a receiving table such that the unfired pillar shaped honeycomb body stands thereon; conveying the unfired pillar shaped honeycomb body placed on the receiving table; drying the unfired pillar shaped honeycomb body after the conveying step, or drying the unfired pillar shaped honeycomb body during the conveying to obtain a honeycomb dried body; and firing the honeycomb dried body to obtain a honeycomb structure. The receiving table includes at least one protrusion. In the honeycomb formed body conveying step, the unfired pillar shaped honeycomb body is conveyed while supporting it by inserting the at least one protrusion of the receiving table into a bottom surface of the unfired pillar shaped honeycomb body placed on the receiving table.
RECEIVING TABLE FOR HONEYCOMB FORMED BODY, METHOD FOR PRODUCING HONEYCOMB FORMED BODY, AND METHOD FOR PRODUCING HONEYCOMB FIRED BODY
A receiving table 100 for supporting a side surface of a honeycomb formed body, the side surface being parallel to a cell extending direction. The receiving table 100 comprises: a body portion 10 having a groove 11 extending in one direction; a support portion 20 comprising: a flexible sheet substrate 21 in contact with a surface of the groove 11 of the body portion 10; and a foam layer 22 attached to the flexible sheet substrate 21, the foam layer 22 being brought into contact with the side surface of the honeycomb formed body; and fixing members 30 for fixing the support portion 20 to the body portion 10. The support portion 20 is provided in a non-adhesive state to the body portion 10.

METHOD AND APPARATUS FOR AUTOMATIC EXTRUDATE LOADING AND ALIGNMENT
Disclosed herein is a method and apparatus for automatic extrudate loading and alignment. An extrudate handling system includes a head end assembly and an imaging device (which may be part of the head end assembly). The imaging device is configured to image an end face of an extrudate, and generate, during translation of the extrudate, an imaging output signal indicative of a rotational position of the end face of the extrudate. The head end assembly includes a rotational effector to rotate the extrudate during translation thereof and a fixed effector rotationally fixed relative to a track. The extrudate handling system is able to determine the rotational position of the web angle of the extrudate and precisely adjust the rotational position while linearly translating the extrudate along the track. The extrudate handling system provides greater accuracy, reduced costs, and improved results.
METHOD FOR PRODUCING HONEYCOMB STRUCTURE
A method for producing a honeycomb structure including producing an unfired pillar shaped honeycomb body; placing the unfired pillar shaped honeycomb body on a receiving table such that the unfired pillar shaped honeycomb body stands thereon; conveying the unfired pillar shaped honeycomb body placed on the receiving table; drying the unfired pillar shaped honeycomb body after the conveying step, or drying the unfired pillar shaped honeycomb body during the conveying to obtain a honeycomb dried body; and firing the honeycomb dried body to obtain a honeycomb structure. The receiving table includes at least one protrusion. In the honeycomb formed body conveying step, the unfired pillar shaped honeycomb body is conveyed while supporting it by inserting the at least one protrusion of the receiving table into a bottom surface of the unfired pillar shaped honeycomb body placed on the receiving table.
ASSEMBLY AND USE OF A GEOMETRICALLY COMPACT POWDER LAYER
The invention relates to an additive production method involving the production of a layer of geometrically compact particles, having the following steps: a) providing a particle layer depositing arrangement, comprising a first and a second semi-chamber, wherein a partition separates the first semi-chamber from the second semi-chamber, and the partition is permeable for a dispersion medium and impermeable for particles dispersed in the dispersion medium; b) providing a particle dispersion comprising the dispersion medium and particles dispersed therein in the first semi-chamber, the particle dispersion being distributed substantially homogenously in the first semi-chamber; c) generating a pressure gradient between the first and the second semi-chamber such that the pressure gradient in the first semi-chamber causes a particle dispersion flow directed towards the partition; and d) depositing a particle aggregate material comprising geometrically compact particles on the partition by transporting a dispersion agent into the second semi-chamber.
