Abstract: An apparatus for applying a longitudinal line or strip of marking material on a roadway which employs a fluid marking material and which provides spaced transverse strip areas of increased depth, the apparatus comprising a supply hopper for the marking material which opens at the rear to allow material to flow onto the roadway surface between spaced side edge defining members and a rear end plate member which is mounted for intermittent vertical reciprocation so as to provide for deposit of cross strips of the marking material which are of different depth or height. The end plate is also mounted for reciprocation longitudinally of the apparatus so as to push the marking material back into the hopper at the end of each section of the longitudinal strip.
