Abstract
The oil pattern laid down by the automatic machine across the width of the lane and along the length of the lane can be precisely controlled and varied through the use of a series of independently controllable wick assemblies that are individually movable into and out of contacting engagement with the oil applicator of the machine. A programmable controller for the wick assemblies determines which of the wick assemblies will be in oil-transferring contact with the applicator and when.
