Abstract

See full text

There is provided a drum head assembly. The drum head assembly has an outer member and an inner member. The outer member has an L-shaped step on its inside surface with posts extending outward from the base of the step. The depth of the inside edge of the outer member determines the amount of tension on the head. A die cut head or skin with holes punched to match the posts is inserted into the outer member. The inner member with holes that match the posts in the outer member is pressed onto the underside of the outer member. The pressure forces the inner member into the inside edge of the L-shaped inside surface of the outer member. There is also provided a method in which the die cut head or skin gets pulled at the same time, thus creating tension. While the assembly is still under pressure, a heated mandrel melts the post ends onto the inner member, thus holding the three components of the assembly in place.
