Bubble-type foam generator has foam generating space of constant volume. Area of diametrical surface of foam generator bubbler is equal to or smaller than area of foam generation annual surface. Foam accumulators are made in the form of telescopic joint of at least two tubular members with at least one plated foam stabilizer arranged at outlet end of outer tubular member. Foam applied onto field surface is of high quality allowing wide range and kinds of marks to be formed, beginning from discrete marks of various lengths to continuous flow of foam.
