A bowling lane maintenance machine utilizes flexible wick segments to transfer lane dressing to the applicator roll of the machine. The wick segments are caused to flex into and out of contacting engagement with a transfer roll associated with the applicator roll by rotatable cams that engage cam followers associated with the wick segments. The cams are all secured to a common cam shaft and are rotated in unison through successive short segments of rotational travel by an indexing motor that responds to a controller. Each wick segment has at least one spring that urges the segment into contacting engagement with the transfer roll, while the cam for that segment is disposed to engage the follower and flex the wick segment off the transfer roll against the action of the spring when the lobe of the cam is in contacting engagement with the follower.
