Arrangemang och anordning i en arkformningsmaskins torkparti för kontroll av luftflöden vid spetsdragning

摘要

The invention relates to an arrangement in a dryer section of a web forming machine for controlling air flows during tail threading. A tail is arranged to be taken from a dryer cylinder (10) to a turning roll (12) in several positions of the dryer section (32) over an interval (16) supported to the fabric (14), and the dryer cylinder and the fabric form an opening gap (15, 15.1). The gap is arranged to be covered at least partially on the outside of the tail for restricting air flows in the cross-machine direction in connection with the opening gap. In addition, the invention also relates to a corresponding method and device.
