Abstract
Abstract An apparatus arrangement and method for the generation of a fiber containing foam and the draining of the foam substantially immediately following its formation is disclosed. The draining on a foraminous support commences within about 100 milliseconds of the termination of the aciton which generates the foam. The conveying of the foam from the generation zone to the foraminous support is such that the fibers are not significantly changed in their orientation by movement to the foraminous support. The foam is formed in a wide, thin ribbon so that lateral spreading of the foam to attain sheet width is not necessary.
