Description of the Related Art Conventionally, in an automatic laver winding machine, plate rice cooked by a compression transfer mechanism is conveyed by an intermittent carry-out conveyor belt, and the plate rice is cut into a fixed amount (length) by a cutting mechanism. A certain amount of cooked rice is conveyed by the supply conveyor belt, dropped and supplied onto the laver sheet placed on the rice cooked laver wrapping plate of the forming mechanism, and folded up inward by the raising of the push-up arm. It is known that a part of the laver is folded at the same time and is wrapped with a laver sheet to produce a laver roll having a substantially square cross section.

According to the above automatic laver winding machine, a thick or thin laver can be manufactured by forming the plate-like cooked rice into a thick or thin plate.
