PCT No. PCT/US86/00374 Sec. 371 Date Feb. 21, 1986 Sec. 102(e) Date Feb. 21, 1986 PCT Filed Feb. 21, 1986.A vacuum device (15, 15') and method for avoiding sheet flutter in an on-running tangent pocket (14, 14') defined between the perimeter of a dryer roll (9, 9'), and a free transitional span (13, 13') of a dryer felt (7, 7') travelling toward the dryer roll and carrying a wet paper sheet web (8, 8') on the face of the felt outside of the tangent pocket. The device comprises an elongate hollow manifold (17, 17') arranged to extend longitudinally within the pocket (14, 14') parallel to the felt (7, 7') and web (8, 8'). The air in the pocket (14, 14') is vacuumed into a chamber (16, 16') within the manifold (17, 17') through an arrangement of ports (21, 21', 22, 22') communicating with the vacuum chamber. A suction member (20, 20') draws the air from the vacuum chamber (16, 16') and communicates with a vacuum source (34).
