US 8,403,249 B2 · System and method for storage and temporary installation of secondary flooring surface

Abstract

Systems and methods of rolling and unrolling secondary flooring surfaces, such as tall pile polyethylene turf, are provided. The system includes a drive system that allows for the conversion of a primary surface into a secondary flooring surface in a relatively short period of time. The drive system includes core adjustable speed drive units for controlling the speed and torque of the motors that drive the core, as well as roller adjustable speed drive units for controlling the speed of the front roller. The core adjustable speed drive units control the torque of the core motors during roll up and control the speed of the core motors during roll out.
