Patent number: 4130915Abstract: This invention relates to a carding process for forming a nonwoven fibrous structure including a blend of short fibers under 1/4 inch in length and longer reinforcing fibers. In accordance with the process fibers are separated from a fibrous feed by engaging the feed with projections on the periphery of a main carding drum that is rotating at a surface speed of at least 12,500 feet/minute. The rotating main drum directs the fibers into a working section in which projections on rotating worker and turner satellite rolls cooperate with the projections on the main drum to individualize the fibers and blend them together. The necessary interaction between the projections of the main drum and the projections of the satellite rolls to both individualize and blend the fibers is achieved by pressurizing the working section to a level that minimizes undesirable air flow characteristics about the satellite rolls.Type: GrantFiled: September 19, 1977Date of Patent: December 26, 1978Assignee: Scott Paper CompanyInventors: Joel P. Gotchel, Henry J. Norton
