The apparatus for applying to a road, (1), run-way or equivalent a point-formed or dotted paint or marking (M''), especially a traffic indication line comprises a reservoir (R) containing a supply of highly viscous material (M) to be applied to the road (1) and a nozzle section (10,10') in itself comprising conduits (11) ending in orifice zones (11',11'') for forming preliminary stages (M') of highly viscous drops and means (20,20',20'') for flinging the drops down into engagement with the road (1). In a mechanical embodiment the orifice zones (11') of the conduits (11) are placed on a cylinder surface (12) and are mutually separated by means of partition walls (13) and the means (20) for flinging the material down into engagement with the road comprise a rotatory shaft (21) and a number of shovel blades (22). In a pneumatic embodiment the means (30) for flinging the drops down into engagement with the road (1) comprise a plurality of compressed air tubes (20') each leading to an orifice zone (11'') and another plurality of tubes (20'') leading away from the said zone ('11''). These apparatus constitute simple and cheap embodiments of an apparatus which effectively flings the marking mass into contact with the road. |
