ABSTRACT OF THE DISCLOSURE At least a substantial proportion of the fibers in papermaking stock are delivered in cross direction orientation to the slice chamber of a headbox and remain in the cross direction orientation for delivery from the slice chamber to a forming surface. The cross direction orientation is effected by a set of partitions defining stock flow passages extending obliquely in the cross direction, receiving the stock flowing in the machine direction and biasing the streams of the stock to flow in generally the cross direction to the downstream ends of the passages from which the streams are diverted in substantially the machine direction towards the slice chamber. The stock with fibers oriented in the cross direction may be supplied to turbulence controlling channels in the slice chamber.
