Abstract
A lane maintenance machine has a cleaning system that includes at least one cleaning liquid dispensing head which reciprocates back and forth transversely of the lane as the machine travels along the length of the lane. In a preferred embodiment the dispensing head emits successive squirts of liquid from a positive displacement pump, such as a peristaltic pump. The positive displacement pump provides accurate, precise metering of the cleaning liquid and affords board-by-board control of the dispensing action. A wiping assembly immediately behind the cleaning liquid dispensing head provides a web of cloth-like material looped under a compressible backup roller to wipe the applied liquid into a thin film and to pick up a measure of the liquid along with oil and dirt. A vacuum squeegee pickup head trailing the wiping assembly lifts the remaining film of cleaning liquid completely off the lane surface, whereupon lane dressing is applied at the rear of the machine utilizing a dressing dispensing head that, like the cleaning liquid dispensing head, reciprocates transversely of the lane to dispense dressing in a pattern preselected by the operator.
