Abstract
An apparatus for increasing the width, or cross-machine-direction dimension of a fluid-entrained (e.g., air-entrained) stream of fibers to form a fibrous web that is wider than the stream of fibers. A rotatable spreading roll having a foraminous outer surface obliquely intercepts the open downstream end of a conveying duct through which the fluid-entrained stream of fibers is directed, and an intermediate web, wider than the stream of fiber in the first conveying duct, is deposited on this foraminous surface. The spreading roll is rotated to direct the intermediate web into communication with the upstream end of a second conveying duct, and a pressure differential established through the apparatus functions to relaunch the fibers of the intermediate web into the second conveying duct, and ultimately onto a foraminous forming surface to form a fibrous web product that is wider than the initially formed stream of fibers in the first conveying duct.
