ABSTRACT:
A drive roller unit for driving an article on a conveyor track includes a drive roller which can be driven in rotation by an electric motor. The drive roller is in the form of a hollow circular cylinder and the motor is accommodated in the interior thereof. The drive roller is non-rotatably connected to the stator of the motor in concentric relationship with the axis of rotation of the rotor of the motor. A runner wheel disposed at least at one axial end of the rotor shaft is in engagement with a guide track mechanism which is fixedly connected to the base of the unit and which leads upwardly with respect to the base, the runner wheel rolling along the guide track mechanism to raise the drive roller into an upper operative position to engage an article to be driven thereby. The guide track mechanism may be in the form of a guide wheel co-operable with the runner wheel.
