The arrangement is for the axial driving of a supply hose (11) for pressure medium or application medium in the form of fluid, gaseous or solid, granule-formed or powder-formed, material. The supply hose (11) is connected to a displaceable cartridge (42) provided with at least one spray nozzle (43). The cartridge (42) is arranged in a guide tube (41) along an object that is to be sprayed. The arrangement has three driving wheels (21), where at least one driving wheel (21a) is driven by driving means and where each driving wheel (21) has a concave jacket surface (27) congruent with the supply hose (11). The concave jacket surface (27) surrounds the supply hose to at least 100° degrees of the circumference of the supply hose (11).
