[0003]

However, in the above-mentioned conventional square-shaped laver roll forming apparatus, the terminal rectangular plate bends inward only to a substantially horizontal position in the final forming of the cooked rice laver roll wrapping plate. There are problems as described in.

Since the pressure on the cooked rice and the seaweed sheet is insufficient, it is difficult to obtain a square seaweed roll in which each corner portion of the seaweed sheet is made uniform and folded almost at right angles.
With the passage of time, each corner of the laver sheet greatly expanded into a round shape, which was a factor of deteriorating the commercial value.

In addition, due to the restoring force of the seaweed sheet, the upper seaweed sheet portion (the upper surface portion of the square-shaped seaweed roll) wrapped around the cooked rice is often peeled off from the cooked rice during the forming process, which is accurate for cooked rice. There were problems such as hindrance to the wrapping and its work.

The present invention has been made in view of the above-mentioned problems of the above-mentioned prior art, and is the upper surface of the terminal rectangular plate of the cooked rice laver wrapping plate of the square-shaped laver roll forming apparatus, or the rectangular shape of the central portion. On the upper surface of both the plate and the terminal rectangular plate,
By providing a pressing plate that further presses the cooked rice in the terminal rectangular plate that is bent into a square shape at the time of molding, it is possible to eliminate the pressure shortage on the cooked rice or seaweed sheet, so that each corner is made uniform.
