Abstract:
1. A device for covering an object to be transported in an air stream generated by forward or backward movement of the object, the device comprising: a cover which at least partially traverses the object; and a differential pressure device disposed on the cover which creates a pressure differential between air under the cover and air passing over or around the cover; wherein the pressure differential causes the air under the cover to exhaust to an exterior of the cover, drawing the cover toward the object; and wherein the pressure differential device creates the pressure differential when the direction of transport is at least one of forward or backwards; wherein the pressure differential device comprises a body member and wherein the cover comprises at least one aperture formed therethrough, the body member delimiting at least one pathway from the at least one aperture to the exterior of the cover; wherein the differential pressure device further comprises a base affixed to the cover proximate to the at least one aperture such that the body member extends at least partially over the aperture; wherein the pressure differential device further comprises at least one open end, the at least one pathway extending from the aperture to the at least one open end, wherein the at least one pathway is positioned substantially perpendicular to a direction of the air stream and the direction of transport, the at least one pathway being configured and positioned on the cover to remain substantially perpendicular to the direction of the air stream and the direction of transport when the object is vertically tilted 0 to 15 degrees upwards or 0 to 15 degrees downwards.
