摘要

A process and apparatus for laying highly ordered webs wherein a fibrous strand forwarded towards a collecting surface is caused to oscillate up to an amplitude equal to the desired web width and by passing between two closely spaced plates is laid in successive courses with a very high degree of parallelism and precision. A plurality of the laying devices may be used to produce thicker or wider webs or webs having layers of differing orientation directions. Various bonding methods may be applied to the ordered webs.
