Patent ID: 8540180

Claim:
An apparatus, comprising: a frame having a vehicle coupling portion and a roller portion, the vehicle coupling portion configured to be coupled to a vehicle, the vehicle configured to move along a surface to distribute a substantially cylindrical roll about the surface such that a diameter of the substantially cylindrical roll is decreased from a first diameter to a second diameter when the substantially cylindrical roll is distributed about the surface; and a plurality of rollers coupled to the roller portion of the frame such that a rotational axis about which a first roller from the plurality of rollers rotates is non-coaxial to a rotational axis about which a second roller from the plurality of rollers rotates, and such that when the vehicle coupling portion of the frame is coupled to the vehicle the first roller from the plurality of rollers and the second roller from the plurality of rollers are each disposed between the vehicle and a vertical center line of the substantially cylindrical roll, the first roller from the plurality of rollers is configured to contact a first contact portion of the substantially cylindrical roll when the substantially cylindrical roll has the first diameter, the first roller from the plurality of rollers being spaced apart from substantially cylindrical roll when the substantially cylindrical roll has the second diameter, the second roller from the plurality of rollers is configured to contact a second contact portion of the substantially cylindrical roll when the substantially cylindrical roll has the first diameter and when the substantially cylindrical roll has the second diameter, the second contact portion of the substantially cylindrical roll disposed between the surface and a horizontal center line of the substantially cylindrical roll.
