  • Patent number: 8221589
    Abstract: 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.

  • Patent number: 6955107
    Abstract: Support and positioning means (10) and a cutting head (13) supported on them extend in the operating position of the area of the edge part (14?) of a paper web (14). In the cutting head (13), there is a support surface (16) and at least one nozzle (17), which is set in such a way that the edge part (14?) travels between the support surface (16) and the nozzle (15). The equipment includes mechanical cleaning means (20) and/or a cleaning construction (21) for keeping the support surfaces (16) clean. The cleaning means (20) and/or cleaning construction (21) are arranged on the opposite side of the paper web (14) to the nozzle (17).
