Abstract
A ball feeding arrangement () comprising: a rotor element () for pushing a ball (); a transmission element () connected to the rotor element; and a drive element () for driving a rotational movement of the rotor element () via the transmission element (), which drive element () is intended to be driven by a drive motor (), wherein one of the drive element () and the transmission element () has at least one protrusion (-), and the other of the drive element and the transmission element () has a guiding surface () adapted to guide the at least one protrusion (-) during relative rotation between the drive element () and the transmission element (), wherein the at least one protrusion (-) is yieldingly biased against the guiding surface (), wherein the biasing force, a shape of the guiding surface () and a shape of the at least one protrusion are adapted to enable transfer of a rotational force of a given magnitude from the drive element () to the transmission element () such that a relative rotation between the drive element () and the transmission element () occurs when the rotor element () is subject to a rotational resistance greater than the given magnitude, wherein the biasing force, a shape of the guiding surface () and a shape of the at least one protrusion (-) are further adapted such that, occasionally during relative rotation between the drive element () and the transmission element (), a pressure is generated between the at least one protrusion (-) and the guiding surface () that urges the transmission element () to rotate in a rotational direction opposite a rotational direction of the drive element ().
