Abstract: A bowling ball surface treatment device for abrading, polishing or cleansing a bowling ball includes a housing, a ball displacing unit movably mounted to the housing for holding the bowling ball in a rotatable manner and for reciprocatingly displacing the bowling ball between a temporary waiting region and a surface treatment region, a surface treatment disc for supporting and spinning the bowling ball in the surface treatment region, the surface treatment disc having a surface treatment element for making frictional contact with the bowling ball, a temporary support disc for temporarily supporting the bowling ball in the temporary waiting region when the bowling ball is moved out of the surface treatment region, and a disc drive unit for rotatingly driving the surface treatment disc and the temporary support disc.

Abstract: A bowling ball surface treatment apparatus is designed to uniformly abrade and polish a bowling ball. The apparatus includes a housing and a ball movement guider provided inside the housing for guiding movement of a bowling ball and confining the bowling ball within a limited surface treatment area, and a surface treatment disc arranged below the ball movement guider for supporting, rotating and revolving the bowling ball. The surface treatment disc has a disc shaft and a surface treatment element for abrading or polishing the bowling ball. The apparatus further includes a disc rotating device for rotating the surface treatment disc about a disc center axis and a disc revolving device for rotatably holding the disc shaft of the surface treatment disc and for causing the surface treatment disc to make revolving movement around a sun axis offset from the disc center axis.

Abstract: A bowling ball surface treatment machine includes a housing and a ball movement guider provided inside the housing for guiding movement of a bowling ball, the ball movement guider having a guider center axis and an inner circumferential surface. A surface treatment disc with a surface treatment is arranged below the ball movement guider for supporting and rotating the bowling ball. The surface treatment disc has a disc center axis deviating from the guider center axis. The machine further includes a disc driving motor for rotating the surface treatment disc about the disc center axis and a controller for allowing the disc driving motor to repeatedly accelerate the surface treatment disc to a target rotation speed, rotate the surface treatment disc in a surface treatment position at the target rotation speed for a predetermined running time and then decelerate the surface treatment disc toward a zero speed.

Abstract: A ball cleaning and polishing machine is provided comprising a housing, a cleaning barrel extending vertically upwards from the housing and having a cylindrical interior surface, a turntable adapted to support a plurality of game balls within the cleaning barrel and provided with a cleaning fabric remaining in contact with the game balls, an impeller coaxially mounted above the turntable for rotation relative to the turntable and for keeping the game balls isolated from one another, and an electric motor drivingly connected to the turntable for causing the turntable to rotate such that the game balls can be rubbed with the cleaning fabric. Provided on the interior surface of the cleaning barrel is a cushion lining which has a plurality of protuberances each substantially uniformly spaced apart in a circumferential direction of the lining. The machine also employs a squeezable see-through fluid container which can be replaced with a new one when the cleaning fluid runs dry.
