Abstract
In the production of a nonwoven fabric of thermally bonded fibers, a heavy web of fibers is continuously fed to a toothed cylinder at a slow speed to form a layer of fibers, and a portion of this layer is removed and formed into a lightweight uniform web at a faster speed. The second web is conveyed without draw to a calender having a bonding nip, and the fibers of the web are rearranged by compression and heating and are supported on a hot surface of one of the calender rolls prior to entering the nip to additionally improve uniformity.
