Paint roller

A painter holds the roller by the handle section.

It is possible to clean and reuse a roller cover, but it is also typically disposed of after use.

An innovation of the cylindrical core has allowed it to contain paint inside, with the cover absorbing paint from the inside and filtering it through (naturally by wicking) to the cover's exterior when the roller is rolled, and thence onto the surface being painted.

[2] In the United States, Richard Croxton Adams produced a paint roller in a basement workshop in 1940[3] and patented it in the United States.

[4] However, a similar paint roller patent application was filed in the United States two years earlier in 1940 by inventor Fride E.
