Abstract: A method for depositing at least two components having dissimilar compositions on a cylindrical surface is disclosed wherein the method comprises the steps of:(a) rotating the cylindrical surface about its axis;(b) locating a mixing head a short distance from the cylindrical surface, said mixing head being connected to separate supply means for each of said components via flow controlling means;(c) opening a first flow controlling means thereby supplying a first component to the mixing head;(d) moving the mixing head in the axial direction along the cylindrical surface while depositing the first component from the mixing head onto the cylindrical surface;(e) opening a second flow controlling means to the extent necessary to supply a second component to the mixing head at a flow rate lower than that at which the first component is supplied;(f) gradually decreasing the flow rate of the first component while gradually increasing the flow rate of the second component until the flow of the first component is termi
