ABSTRACT:
A cover system for covering open topped containers such as truck trailers carrying particulate material such as dirt, gravel, grain and the like. The cover is a flexible sheet material sized to cover the open top and can extend over the end and down the sides of the container, if desired. A roller is provided at one end of the open top for rolling up the cover to store the cover with the top open. A transverse rod runs through a hem at the opposite end of the cover. Edge guides on the rod maintain the cover in alignment with the container top when the cover is unrolled over the top. At least one freely rotatable roller or slide is provided on the rod near the rod center. A rope, strap or the like is secured to the rod to pull the rod and cover over the open top. The roller or slide allows the leading end of the deploying cover to ride up and over any heaped granular material in the container to avoid the edge digging into the material, which could prevent further deployment of the cover and could result in spillage of material forced onto the top of the cover.
