Title: Formation of adjustment-free head
Inventor: DONARUDO RICHIYAADO HAATORII
IPC: G10D1/10
Filed: 1982-04-02
Abstract: A method of forming a non-tunable head for a drum, banjo, tambourine, or similar musical instrument is described. A highly oriented crystalline polymeric film (12) is immersed into a liquid solvent bath containing a halogenated methane compound until the film swells to become sufficiently soft so that it can be draped. The film is then removed from the solvent bath and preferably mechanically wiped to remove solvent remaining on its surface. The film is securely attached to an annular member (20) before it dries, and is then dried by allowing the solvent to evaporate. As the film dries, it shrinks to substantially its original dimensions to provide a constant tension in the head. The heads formed by this method have sufficient tension to provide an effective musical tone without the utilization of clamping or stretching means which mus be periodically readjusted to maintain a desired tension in the head.
