Zusammenfassung:	Paper stock enters a tapered header at the large end and, except for a small percentage that is recirculated, is delivered to a papermaking machine through a large number of flow channels or hoses divided into two groups. The hoses of one group are connected to the header along a first row of openings, and the hoses of the second group are connected to the header along a second row of openings. The openings are spaced apart from each other both circumferentially and longitudinally of the header. The downstream ends of all the hoses lie in a single plane, and the hoses of the two groups lie respectively in surfaces curved concavely towards each other.
