2. Description of the Related Art Generally, there are known nori-maki sushi, which have a columnar shape (hereinafter referred to as "nori-maki") and a substantially loose-cone shape, so-called hand-rolled sushi.

At present, in the above-mentioned seaweed roll, automation of the seaweed roll forming machine is in progress in order to meet the large demand.

The conventional seaweed roll forming machine supplies a fixed amount of cooked rice onto the seaweed sheet placed on the cooked rice seaweed roll wrapping plate in the forming mechanism, and wraps it with the cooked rice seaweed roll wrapping plate. It is a structure for manufacturing a cylindrical laver roll.

[0005]

However, since the conventional seaweed roll forming machine described above cannot be used for hand-rolled sushi which has a fundamentally different shape from seaweed roll, it has become popular in recent years. In order to meet the growing demand for hand-rolled sushi, establishment of an automated sushi manufacturing apparatus is desired by those skilled in the art.

The present invention has been made in view of the above-mentioned conventional circumstances, and is an automated hand-rolled sushi product capable of efficiently producing high-quality hand-rolled sushi products having a certain hardness and shape. An object is to provide a manufacturing apparatus.
