发明名称 Laminated head of plastic sheet material and a synthetic fabric material having random fiber orientation
摘要 A head for a drum or similar musical instrument comprising a synthetic plastic sheet material and a synthetic fabric material having a random fiber orientation which is laminated thereto. The synthetic plastic sheet material remains the primary tension load carrier while the fabric material having nonorientated fibers is laminated thereto to distribute load without transferring stress into the plastic sheet material, thereby reducing the tendency of the plastic sheet material to dent as well as damping undesirable overtones, and to provide an improved brush surface. The synthetic fabric material is preferably impregnated with a water-based resin emulsion system to insure that the nonorientated individual fibers are elastomerically bonded together, thereby increasing the fabric materials' intralaminar integrity and to further enhance the tone quality of the laminated head. Lamination and impregnation in this manner provides a laminated head having an improved sound by increasing resonance and projection with a reduction of harmonic dissonance and provides a playing surface having improved brush response, thereby also resulting in improved brush sound.
