ABSTRACT:
BACKGROUND OF THE INVENTION
The invention relates to a roller for applying paints or similar application masses to surfaces or articles.
It is an object of the present invention to provide a roller which with economical execution and simple handling enables time-saving, uniform and drip-free application of paints or other application masses.
SUMMARY OF THE INVENTION
To accomplish this objective, a roller is made with an inner drum which forms a reservoir for the paint and with a peripheral surface which is made rotationally symmetrical to a drum axis, and with an outer drum which turns freely and has openings in a peripheral surface which surrounds the inner drum.
In the invention, the outer drum can turn on the inner drum, i.e. the inner drum forms, for example, the bearing of the outer drum, by which an especially good distribution of the paint or application mass results.
