Method and apparatus for bias crosslaying a fiber web
Abstract
Abstract A method for bias crosslaying fiber webs is disclosed. This method includes the use of a pair of endless belts between which a fiber web is imprisoned as it is advanced toward a carrier sheet moving at right angles to the belts. Each belt has an end roller which defines a nip from which the fiber web is discharged and the end rollers are journalled in a support element mounted for reciprocation transversely over and across the moving carrier sheet to crosslay the fiber web thereon at a resulting bias angle. A second pair of belts may be provided parallel to the first pair to bias crosslay a second fiber web on the carrier sheet in substantially edge-to-edge relation to the first web. In the preferred embodiment additional webs of material may be deposited on the carrier sheet in longitudinal relation and bonded to the bias crosslaid components. The edges of the composite material may also be cut and stripped away.
