ABSTRACT:
A two-layer drum cover and a method of producing the same are provided. The two-layer drum cover includes a backing wire constructed of a relatively high grade metal alloy in the warp direction and alternating relatively low grade metal alloys in the shute direction. The two-layer drum cover also includes a face wire constructed of a relatively high grade metal alloy in the warp direction and alternating relatively low grade metal alloys in the shute direction. All the metal alloys used in the face wire have a higher grade than the metal alloys used in the backing wire.
