The invention relates to a method for patching a fibre web, in which method a fibre web (W) is observed by means of a detection device (30) to detect holes in the fibre web. In the method, when the detection device (30) has detected a hole in the fibre web, at least one piece of patching tape (31) is detachably adhered to a tape applicator roll (22). The patching tape (31) is adhered from the tape applica¬ tor roll (22) to the area of the hole in the fibre web (W) when the fibre web (W) is passed over the tape applicator roll (22). The invention also relates to a device for patching a fibre web, which device (20) comprises a detection device (30) to de¬ tect holes in the fibre web (W). The device (20) further comprises an applicator roll (22) for a patching tape (31), over which roll the fibre web (W) is arranged to run. |
