Cleaning roller in bowling lane maintenance system
First Claim
1. A cleaning roller rotatably driven to wipe off a liquid cleaner being applied to a floor, said cleaning roller comprising an elongated core rotatably supportable at the opposite longitudinal ends thereof and an elongated resilient body mounted about said core, said resilient body being made of a cleaning material operable to wipe off said liquid cleaner from said floor and to effect a cleaning action on said floor, said resilient body having a central portion and longitudinal ends inwardly spaced away from each of the opposite longitudinal ends of said core, the external diameter of said resilient body progressively increasing from each of the opposite longitudinal ends of said resilient body toward said central portion to thereby provide for substantially equal pressure contact between said floor and said resilient body along substantially the entire longitudinal length of said resilient body.
