Abstract
A heavy roll dispenser is designed to attach to a tractor via a three-point hitch. The base of the dispenser rides above the earth and supports a chassis, which can move left and right via a hydraulic actuator. The chassis has a pair of powered cradle rollers to receive a heavy roll and dispense the heavy roll with the powered cradle rollers. A guide roller is mounted on the chassis behind the cradle rollers. A pair of powered adjustable width pincer arms stabilizes the heavy roll atop the cradle rollers.

A method of lining a surface by dispensing a roll of a geosynthetic clay liner over said surface comprising:
- top loading a roll of said geosynthetic liner onto a pair of cradle rollers that are supported by a dispenser chassis, at least one of said cradle rollers being driven by a motor for unrolling the roll of geosynthetic clay liner onto said surface, said dispenser chassis being carried by a moving base, for dispensing said roll of geosynthetic clay liner during movement over said surface;
- said dispenser chassis including a transverse mounting assembly including a powered actuator for moving the roll of geosynthetic clay liner transversely left and right with respect to a direction of said moving base while dispensing said geosynthetic clay liner onto said surface,
- wherein the chassis is powered by left and right powered actuators, each actuator powered by a hydraulic piston.
A method of lining a surface by dispensing a roll of a geosynthetic clay liner over said surface comprising:
- top loading a roll of said geosynthetic liner onto a pair of cradle rollers that are supported by a dispenser chassis, at least one of said cradle rollers being driven by a motor for unrolling the roll of geosynthetic clay liner onto said surface, said dispenser chassis being carried by a moving base, for dispensing said roll of geosynthetic clay liner during movement over said surface;
- said dispenser chassis including a transverse mounting assembly including a powered actuator for moving the roll of geosynthetic clay liner transversely left and right with respect to a direction of said moving base while dispensing said geosynthetic clay liner onto said surface,
- wherein the chassis further comprises a pair of adjustable width alignment arms and including the step of sandwiching the roll of geosynthetic clay liner to be dispensed between the alignment arms.
A method of lining a surface by dispensing a single roll of a geosynthetic clay liner over said surface comprising:
- top loading a geosynthetic clay liner consisting of said single roll of said geosynthetic clay liner onto a pair of cradle rollers that are supported by a dispenser chassis, at least one of said cradle rollers being driven by a motor for unrolling the roll of geosynthetic clay liner onto said surface, said dispenser chassis being carried by a moving base, for dispensing said roll of geosynthetic clay liner during movement over said surface;
- said dispenser chassis including a transverse mounting assembly including a powered actuator for moving the roll of geosynthetic clay liner transversely left and right with respect to a direction of said moving base while dispensing said geosynthetic clay liner onto said surface,
- wherein the chassis is powered by left and right powered actuators, each actuator powered by a hydraulic piston.
A method of lining a surface by dispensing a single roll of a geosynthetic clay liner over said surface comprising:
- top loading a geosynthetic clay liner consisting of said single roll of said geosynthetic clay liner onto a pair of cradle rollers that are supported by a dispenser chassis, at least one of said cradle rollers being driven by a motor for unrolling the roll of geosynthetic clay liner onto said surface, said dispenser chassis being carried by a moving base, for dispensing said roll of geosynthetic clay liner during movement over said surface;
- said dispenser chassis including a transverse mounting assembly including a powered actuator for moving the roll of geosynthetic clay liner transversely left and right with respect to a direction of said moving base while dispensing said geosynthetic clay liner onto said surface,
- wherein the chassis further comprises a pair of adjustable width alignment arms and including the step of sandwiching the roll of geosynthetic clay liner to be dispensed between the alignment arms.
A method of lining a surface by dispensing rolls of a geosynthetic clay liner, one at a time, over said surface comprising:
- top loading a roll of said geosynthetic play liner onto a pair of cradle rollers that are supported by a dispenser chassis, at least one of said cradle rollers being driven by a motor for unrolling the roll of geosynthetic clay liner onto said surface, said dispenser chassis being carried by a moving base, for dispensing said roll of geosynthetic clay liner during movement over said surface;
- said dispenser chassis including a transverse mounting assembly including a powered actuator for moving the roll of geosynthetic clay liner transversely left and right with respect to a direction of said moving base while dispensing a first layer of said geosynthetic clay liner onto said surface;
- after dispensing said first layer of the geosynthetic clay liner, dispensing a second layer of the geosynthetic clay liner onto an area of said surface adjacent to the first layer of said geosynthetic clay liner, while operating the powered actuator motor to properly position the second layer thereby overlapping the first and second layers of the geosynthetic clay liner,
- wherein the chassis is powered by left and right powered actuators, each actuator powered by a hydraulic piston.
