Schaberanordning för lösgörande av banan från en rörlig yta i en fiberbanmaskin
摘要
In a method for detaching a web threading tail from a moving surface in a fiber web machine, the web threading tail (12) is detached from a moving surface (23) by means of air that flows from a blow-off blow channel (19) included in a blade holder (14). A trailing blow (26) is directed to the web threading tail (12) using air that flows from a trailing blow channel (17) included in the blade holder (14). The blade holder (14) includes a flow surface (32), and the trailing blow (26) is blown to the same direction with or in a small angle relative to the flow surface (32). The invention also relates to a corresponding blade holder and a doctor apparatus for detaching a web threading tail from a moving surface in a fiber web machine.
