Embodiment Construction

[0012] figure 1 A portion of a circular drumhead 10 is shown having a center 12 and a generally circular membrane-like material 14 extending outwardly in a generally flat manner and inwardly at the periphery at a collar region 16. Extends down into the hoop 18. The film-like material comprises a plastic (typically Mylar) base film 20 and a coating 22 attached to the base film. The circular area 24 inside the collar 16 forms the striking area of ​​the head after the head 10 is mounted on the shell (not shown).

[0013] A coating 22 is applied to the base film 20 before the film material 14 is attached to the ferrule 18 . According to the invention, said coating 22 is a cured polymeric material obtained by crosslinking during curing, which adheres strongly to the base film 20 as it hardens, thereby providing considerable strength and Durability to withstand the forceful contact of percussionists with sticks, brushes, etc.

[0014] Preferably, the coating 22 is applied to a l...

Abstract

A drumhead and a method for coating a drumhead membrane comprising applying a coating having cross linkable polymeric material to the membrane and applying energy to cross link the polymeric material and thereby permanently adhere the material to the membrane as a play surface. The cross-linking not only hardens the coating to improve durability, but also improves the adhesion of the coating to the base film. Actinically cured coatings can completely harden in a matter of 3 to 5 seconds, with UV cured inks being especially desirable.

Description

technical field [0001] The present invention relates to tympanic heads, and more particularly to the membranes and associated play surfaces of tympanic heads. Background technique [0002] Typically, drumheads are manufactured by treating a plastic film or membrane according to the desired acoustic properties while the membrane is tensioned over the supporting edge of the shell. The treated film sheet is cut and formed with a collar region which is fixed into a circular hoop wherein the part is joined by tensioning the parts on the drum shell. Round hoop. The circular area within the hoop defines a striking surface on which a percussionist can produce various sounds using, for example, drumsticks or brushes. [0003] A plastic film, such as Mylar, is often ink-coated using a mesh screen to achieve coloration and subtle changes in the acoustic response of the drumhead. Typically, inks are dried by evaporation in an oven or under heat lamps. The drying time is usually 3 ho...
