Abstract
A method of forming a cover sheet over an opening of a rotary electric device such as a trimmer capacitor or a variable resistor. The rotary device includes a rotor located in a housing or case which is accessible through the opening and adjustable by a screwdriver or similar tool. To form the cover sheet, pliable resin is extended while in an unhardened state to form a film. The case is pressed against the film to introduce a part of the film into the opening. Then the resin material forming the film is allowed to partially harden before the case is separated from the film. As a result, part of the film remains in the opening of the case to form the cover sheet. As the film is completely hardened a functional cover sheet over the opening is produced.
