ABSTRACT:
The roller screen arrangement includes a plurality of roller systems and a motor for driving the rollers of the roller system. Each roller system includes a drive shaft drivable by the motor driver and a roller associated with the drive shaft. One end of the drive shaft is disposed adjacent to one end of the roller and insert means are inserted into a hollow core of the roller at the one end of the roller. A threaded opening extends through the insert means and centrally thereof. A central screw is mounted in the hollow core of the drive shaft such that a threaded portion of the central screw extends outwardly of the drive shaft at the one end of the drive shaft, the threads of the central screw mating with the threads of the threaded opening and the central screw being rotatable relative to the drive shaft when mounted in the hollow core of the drive shaft. To connect the roller to its associated drive shaft for rotation therewith, the central screw of the drive shaft is screwed into the threaded opening of the insert of its associated roller.
