Abstract
Disclosed are cover systems for covering product such as grain. An example cover system includes a cover having at least one perforated tunnel extending across at least a portion of the cover (e.g., with an end to or beyond an edge of the cover). The perforated tunnel can include a bottom membrane with perforations, a cap strip membrane attached to the top side of the bottom membrane, and an air permeable filler material between the bottom membrane and the cap strip membrane. The perforated tunnel can have an air inlet at its end for drawing in air to hold down the cover by suction.
Claims39
Cover System with Perforated Tunnels
- A cover system, comprising:
- a cover having at least one cover section with a perforated tunnel extending across a at least a portion of the cover section, wherein the cover section includes:
- a bottom membrane with perforations,
- a cap strip membrane attached to the bottom membrane, the cap strip membrane and bottom membrane defining the tunnel therebetween;
- an air permeable filler material in the tunnel between the bottom membrane and the cap strip membrane;
- and
- an air inlet at an end of the tunnel.
Method of Manufacturing a Cover System with Perforated Tunnels
- A method of manufacturing a cover system, comprising:
- a) perforating a bottom membrane with a strip of perforations;
- b) placing a strip of air permeable filler material adjacent the strip of perforations and between the perforated bottom membrane and a cap strip membrane;
- and
- c) attaching the cap strip membrane to the bottom membrane to form a cover membrane with a perforated tunnel having a bottom side with the strip of perforations.
The cover manufacturing method of 28, wherein the bottom membrane includes sides extending beyond the edges of the cap strip membrane, wherein a first one of the sides is welded to a first cover section and a second one of the sides is welded to at a second cover section.
Method of Installing a Cover System with Perforated Tunnels
- A method of installing a cover system over a product, comprising:
- placing a cover over the product, the cover including multiple perforated tunnels including first and second perforated tunnels;
- cutting the cover along a side of each of the first and second perforated tunnels;
- and
- rolling up a portion of the cover between the first and second perforated tunnels.
