Abstract
Abstract A knitted metalized yarn gasket fashioned from a core, a first tubular layer formed from a hot melt yarn around the core, and a second tubular structure knitted from a conductive yarn and disposed over at least a portion of the first tubular layer and core assembly. The hot melt yarn forming the first tubular layer adheres the second tubular structure to the core such that fraying of the knit gasket is substantially prevented.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
113 words
A gasket structure for shielding against electromagnetic and radio frequency interference, said gasket structure comprising: a core; a first tubular layer formed from a hot melt yarn and having a length and a transverse dimension, said first tubular layer circumferentially and longitudinally enveloping said core; and a second tubular structure formed from a conductive yarn and having a length and a transverse dimension, said second tubular structure being disposed over at least a portion of said first tubular layer; wherein said hot melt yarn forming said first tubular layer adheres said second tubular structure to said core at a plurality of contact points such that fraying of said gasket structure is substantially prevented.
