Description

[Detailed Description of the Invention] This invention relates to a fold position holding mechanism for a seaweed folding device.

Conventionally, the center line of the seaweed at the folding position, which should form a crease, is pushed upward by the upper edge of the folding plate, and the seaweed is moved between front and rear rollers arranged parallel to the upper edge while maintaining a predetermined distance. In the nori folding device, the nori is folded in half and stored in the double-folded nori storage chamber above the roller when the nori is passed through.
In order to prevent the fold from shifting, a pressing rod is provided that moves up and down integrally with the folding plate and can move up and down. A device has been devised to prevent the crease from shifting by sandwiching seaweed between the top edge.
Since the single pressing rod presses the folding plate from directly above the upper edge thereof, it has a weak ability to prevent slippage, and if the pressing force is increased, the seaweed may be damaged such as cracking.

In this invention, the nori pressing part at the tip of the pressing rod is bifurcated to form the front and rear pressing parts, and the nori is slightly bent in the folding direction at three points: the upper edge of the folding plate and the front and rear pressing parts. The present invention aims to provide a fold position holding mechanism for a seaweed folding device that prevents the seaweed from sliding with a slight pressing force by holding the seaweed in place and prevents the seaweed from shifting without damaging the seaweed. .
