ABSTRACT:
A line marking apparatus adapted in use to be advanced relative to a ground surface in a line marking direction includes a discharge opening region formed between first and second side members for discharge of line marking material therebetween onto the ground surface. The side members extend substantially parallel to the line marking direction and adjusting means is provided for moving the first and second side members towards and away from each other so as to adjust the width of a line to be marked by the apparatus. The adjusting means comprises interconnected pivotable arms, at least one of the side members being supported on the pivotable arms such that relative pivoting of the arms causes the at least one of the side members to move towards and away from the other thereof.
