Abstract
In one embodiment, a bowling lane dressing apparatus has a carriage. With a lane buffer roller and a transfer roller in rolling engagement with the lane buffer roller and in fluid communication with a reservoir containing lane dressing fluid for transferring fluid from the reservoir to the lane buffing roller. A variable speed drive is connected to the transfer roller for rotating it at variable speeds to vary the rate of transfer of fluid from the reservoir to the lane buffer roller. In a second embodiment, the transfer roller is separated into independently rotatable roller segments, each of which can be driven by separate variable speed motors. The segments may comprise a center roller segment driven by one variable speed motor, a pair of track roller segments at opposite ends of the center roller segment, respectively, driven by a second variable speed motor, and a pair of outer roller segments at opposite outer ends of said track roller segments, respectively, driven by a third variable speed motor. In a third embodiment, each roller is driven by a separate variable speed motor.
