Abstract
A device for cleaning a rotary type-carrier, in which a brush which contacts the type-carrier continuously to clean it during normal operation may be moved so that its rotary center is positioned more closely to the type-carrier. As a result, as the brush wears out, it may maintain contact with the type-carrier, obviating the need for frequent replacement.
