Abstract: Systems and methods of rolling and unrolling secondary flooring surfaces, such as tall pile turf, are provided. The system includes a core onto which the secondary flooring surface is rolled, the core being coupled on both ends to a frame that moves along a track mounted on or in a primary surface. 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 frame adjustable speed drive units for controlling the speed of the movement of the frames along the tracks. 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.
