or the like has enhanced resiliency and support at strategic locations due to the use of coil springs interlocked and held within a densified heat bonded low melt fiber batt used as the core or cover of the resilient structure the densified fiber batt core includes low melt fibers which when heated to the melting point and then cooled intersect and interlock with the coil springs the coil springs function as an integral part of the fiber batt eliminating the need for lattice wires and the like to interlock the springs in the structure the invention also increases the capability of manufacturing resilient structures in a wide variety of shapes and sizes application_number US 91051597 A description according to a preferred embodiment of the invention applicant uses a moderately densified heat bonded low melt fiber batt as a starting material such a fiber batt may be formed from a bale of dual polymer fibers 30 as shown in fig1 a such as celbond u00ae staple fibers manufactured by hoechst celanese corporation alternatively high melt or heat stable fibers may be mixed with low melt fibers preferably if a dual polymer fiber is used a bale of the dual polymer fibers is picked and fluffed to a desired degree then tumbled and fed to a feed hopper thereafter the fiber mass is carded by a garneting machine until a desired volume and or density is achieved as is known in the industry densifying a fiber batt of this type involves various stages of heating and compressing to form a predetermined shape the celbond u00ae dual polymer fiber includes a low melt polymer sheath which surrounds a thermally stable polyester.
