Abstract

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.

First claim

The invention claimed is:

1. A receiving table for supporting a side surface of a honeycomb formed body, the side surface being parallel to a cell extending direction, the receiving table comprising:
a body portion having a groove extending in one direction;
a support portion comprising: a flexible sheet substrate in contact with a surface of the groove of the body portion; and a foam layer attached to the flexible sheet substrate, the foam layer being brought into contact with the side surface of the honeycomb formed body; and
fixing members for fixing the support portion to the body portion,
wherein the support portion is provided in a non-adhesive state to the body portion;
the flexible sheet substrate has a thickness of 0.1 to 1.0 mm;
each of the fixing members comprise an L-shaped angle that is in contact with an upper surface of the body portion and the flexible sheet substrate of the support portion, and opening/closing plates provided on two end faces of the body portion perpendicular to a direction where the groove of the body portion extends configured to fix the support portion between the two end faces; and the L-shaped angle portion of each of the fixing members is separate from the opening/closing plates.

2. The receiving table for the honeycomb formed body according to claim 1 , wherein the foam layer is a resin foam layer or a rubber foam layer.

3. The receiving table for the honeycomb formed body according to claim 1 , wherein the foam layer has open cells.

4. The receiving table for the honeycomb formed body according to claim 1 , wherein the flexible sheet substrate is formed of a flexible resin.

5. The receiving table for the honeycomb formed body according to claim 1 , wherein the body portion is formed of a hard resin.

6. The receiving table for the honeycomb formed body according to claim 1 , wherein the flexible sheet substrate is formed of a flexible resin selected from the group consisting of a PP resin, a PET resin, a PC resin, and an acrylic resin.

7. A method for producing a honeycomb formed body, the method comprising conveying a honeycomb formed body resulting from extrusion molding while supporting a side surface of the honeycomb formed body by the receiving table for the honeycomb formed body according to claim 1 , the side surface being parallel to a cell extending direction.

8. The method for producing the honeycomb formed body according to claim 7 , wherein the method comprising cutting the honeycomb formed body supported by a cutting table.

9. A method for producing a honeycomb fired body, the method comprising firing the honeycomb formed body obtained by the method for producing the honeycomb formed body according to claim 7 .
