Abstract: A furnace for manufacturing ceramics is disclosed. The furnace contains a cylindrical heat resistant container, a furnace body for heating the cylindrical heat resistant container, and driving means for driving the cylindrical heat resistant container. The cylindrical heat resistant container rotates about a central shaft. At the same time, a first end and alternately a second end of the cylindrical heat resistant container are raised and lowered periodically, thus creating a seesaw motion while any material contained in the cylindrical heat resistant container is fired by the furnace body.

Abstract: The invention is directed to a method of firing ceramics and a furnace for manufacturing ceramics. Ceramic forms are first fired in a cylindrical heat resistant container in a furnace core tube by using a lateral tubular furnace to increase their mechanical strength. Then, the container is rotated while the ceramic forms are fired further in a predetermined temperature region, which includes a maximum temperature. In this manner the ceramic forms are heated in a uniform state, both thermally and atmospherically, while receiving moderate impact by rotation, and defective appearance and fluctuations in the characteristics of the ceramics are suppressed. In particular, the container is rotated within a temperature region which is higher than the temperature used to start increasing the mechanical strength of the ceramic forms. Further, the ceramic forms can be packed into the container at a higher rate during the rotation portion of the process than during the first firing.

Abstract: The present invention is directed to a method for preparing cylindrical members for paper containers having a thermoplastic resin layer as the innermost layer by cylindrically forming a preform sheet made up of a laminate comprising at least a paper layer and the thermoplastic resin layer, the laminate is arranged so that the thermoplastic layer becomes the innermost layer of the paper containers and is selected from the group consisting of polyesters and ethylene/vinyl alcohol copolymers. The method includes the steps of folding the innermost layer along one edge of the preform sheet back over itself, irradiating the folded edge and another edge of the preform sheet both of which are made of the thermoplastic resin layer of polyesters or ethylene/vinyl alcohol copolymers using a carbon dioxide gas laser irradiation, thereby softening or melting the thermoplastic resin layer, overlapping the irradiated edges, and pressing the overlapped portion to seal the thermoplastic resin layers together.
