  • Method of using zoned hot air knife
    Patent number: 6066221
    Abstract: A zoned hot air knife assembly and process include a plurality of discrete, spaced apart air knives is useful for the inter-filament bonding of nonwoven webs, for the thermal bonding of laminates including nonwoven webs, and other applications. The zoned hot air knife assembly and process facilitate the manufacture of low bond area, low density nonwoven webs and laminates having high structural integrity. The zoned hot air knife also reduces the amount of heated air and, thus, energy required for the production of thermally bonded nonwoven webs and laminates.
