摘要

Starch coating system for a paper machine (100), preferably for a board machine arranged in a sheet forming region (110) of the paper machine comprising at least one first top former (120) and a fourdrinier former (130), comprises at least one first starch coating device (170) for applying a starch suspension on a first fibrous web of the fourdrinier former and at least one first edge-side suction device for suctioning edge-side starch mist. The first starch application device is positioned in the machine direction before a first couched part of the first fibrous web. Starch coating system for a paper machine (100), preferably for a board machine arranged in a sheet forming region (110) of the paper machine comprising at least one first top former (120) and a fourdrinier former (130), comprises at least one first starch coating device (170) for applying a starch suspension on a first fibrous web of the fourdrinier former (130) and at least one first edge-side suction device for suctioning edge-side starch mist. The first starch application device is positioned in the machine direction before a first couched part of the first fibrous web with a second fibrous web of the first top former. The first edge-side suction device is arranged in the machine direction after the first starch coating device and immediately before the first couched part. A machine operatable deflector is provided for sucking the air, which is introduced to at least one first top former.
