Abstract
A bowling lane maintenance machine has a cleaning assembly in which liquid cleaner is deposited on the lane surface at the front of the machine as the machine moves down the lane. Immediately behind the point of application of the cleaning solution, a wiping web assembly spreads the solution across the entire surface of the lane and presses the solution down into the conditioner for subsequent pickup by a suction pickup head behind the wiper web assembly. The web is looped under a backup roll having an exposed fibrous pile face that engages the inside surface of the web while the outside surface engages the lane. The fibrous pile encourages the web to remain in intimate contact with the lane surface at all times while accommodating surface irregularities such as depressions and other variations in lane contour.
