(57) A line marking applicator (10) comprising a frame (12) having an axle (30) on which
is journalled a pair of surface contacting wheels (32) and a marker fluid aerosol
mounting (14,16) positioned on the frame so that, when fitted with an aerosol (15),
marker fluid can be sprayed between the wheels onto a surface, the width of the sprayed
line being defined by, on each of said pair of wheels (32), an integral inner surface
(40) extending continuously from the axle (30) to a rim (42) having a smaller diameter
than that of the wheel rim (44) and which is axially inwardly offset from the wheel
rim to provide a circumferential groove (46); preferably each wheel (32) is provided
with a tyre (44), the diameter (D2) of which is greater than the diameter (D1) of
the inner surface rim (42) and which is axially offset from the inner surface rim
to form the peripheral groove (46).
