[Problems to be solved by the invention]
However, in the configuration of the prior art, the split piece of the wrinkle forming device that wears according to the work frequency is integrated with a metal material, so in order to replace the worn split piece, the whole wrinkle forming device must be replaced. Because it was heavy, it was heavy and it was heavy labor, and it took a lot of time for the replacement work. In addition, since the wrinkle forming device that becomes a consumable part has an integral structure, it is expensive.
[0005]

It has a conical surface with a large directing diameter, and the surface is divided into a plurality of continuous pieces that are radially divided. This piece is a combination of a resin material at the front and a metal material at the rear with respect to the rotational direction. With this configuration, the weight of the wrinkle forming apparatus can be reduced, and only worn parts can be replaced, so that the maintainability is improved.
[0007]
By using a stainless steel material as the metal material that constitutes the divided pieces, the metal material is excellent in wear resistance, and can form a clean cocoon with good soil separation when the cocoon is formed.
[0008]
The metal material that constitutes the split piece has a pressing surface that coincides with a conical surface that increases in diameter outward from one end of the upper surface forming body, and the resin material is polymerized below the pressing surface of the metal material to form a cone.
