However, in the conventional square laver wrapping apparatus described above, the terminal rectangular plate is bent inward only to a substantially horizontal position during the final molding of the cooked rice laver wrapping board. There is a problem as described above.

[0004] Because of the lack of pressure on the cooked rice and the laver sheet, it is difficult to obtain a square laver roll in which the corners of the laver sheet are made uniform and folded almost at right angles.
With the passage of time, each corner and flat portion of the laver sheet expands greatly into a round shape, which is a factor that impairs commercial value.

[0005] In addition, due to the restoring force of the laver sheet, the portion of the upper laver sheet wrapped around the boiled rice (the upper surface portion of the square laver roll) often peels off from the boiled rice during molding and is lifted. There were problems such as disturbing the wrapping and the work.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art. By interlocking with the push-up device so as to descend to the position and stop, it is possible to eliminate insufficient pressure on cooked rice and laver sheets, so that each corner is made uniform and folded almost at a right angle It is an object of the present invention to provide a square laver winding forming apparatus capable of efficiently mass-producing a high-quality square laver winding.
