  • Nonwoven web with improved cut edge quality, and process for imparting
    Patent number: 10329711
    Abstract: A process for producing a nonwoven web material with improved edge quality, and the product thereof, are disclosed. The process may include the steps of forming a batt of polymeric fibers; consolidating the batt in a z-direction and thereby forming a nonwoven web material, conveying the nonwoven web material to a nip between a bonding roller and anvil roller, and impressing a pattern of bond impressions into the nonwoven web material, the bond impressions lying along a cut path. When the web is subsequently cut along the cut path, fibers proximate the cut path are immobilized by the bonds, providing for relatively neater, cleaner cut edges and reducing the number of loose fibers that may be released into the plant environment in downstream processing operations.

  • Method for cutting and sealing an absorbent member
    Patent number: 6562168
    Abstract: A web including a fibrous material and superabsorbent material is fed to a station. The web has a first surface, a second surface, a first side edge and a second side edge. At the station, the operation of applying a superabsorbent material movement obstruction agent and cutting the web into individual absorbent members having a pair of opposing cut ends are carried out simultaneously.
