2. Description of the Related Art In many cases, raw cotton collected from a cotton field is stored in the form of a cotton module compressed and formed in a predetermined shape for two weeks to six months before being sent to a cotton mill. Cotton module still contains raw cotton seeds, needs to be waterproofed to germinate due to moisture such as rainwater and reduce the quality of raw cotton, and because it is piled up, it prevents scattering by wind Measures are needed. The cotton module is usually a rectangular parallelepiped of about several to 10 tons suitable for being directly transported by a truck container.
It has a shape like a height of 2.3 m.

As a method of covering the cotton module, a method of covering the surface with a sheet or a cross sheet made of a waterproof synthetic resin and tying it with a rope or the like can be considered. In the method in which the rope is wound and fixed by tightly covering the rectangular parallelepiped, the sheet is difficult to position, the workability is poor, and the sheet is peeled off by the wind pressure or by the wind. Therefore, attempts have been made to use covers of various shapes according to the shape of the rectangular parallelepiped.

[0004] Many of the conventionally known covers are formed by sewing one sheet so as to cover the upper part of the rectangular parallelepiped. However, when the cover is shallow, the cover is lifted by wind from the side. When the cotton module is transported in a truck container, the lower part of the cotton module is scraped up by a conveyor provided at the lower part of the container, and the length of the cotton module is lengthened. There was a problem that it was stretched and stretched and it was damaged accordingly.

[0005] As described above, the raw cotton needs to be waterproof, and the rainfall on the ceiling surface of the cotton module penetrates into the inside of the cotton module and causes a deterioration in quality. Since the raw cotton has an oil and fat attached thereto and has water repellency, there is a case where a coating is not necessarily required around the lower part of the cotton module except for high quality cotton.

Further, in order to prevent the cover from peeling off due to the wind, a connecting cord is provided on the lower edge of the side of the cover to be locked by a locking member provided at the lower end of the cotton module, or the side of the cover. Is also known as a mesh sheet, but there are problems such as difficult handling, insufficient locking effect, and excessive cost for production, and further improvement is desired. I have.
