Patent ID: 6892589

Claim:
A proof testing method for optical fibre where a fibre is guided in a direction of motion to a first pulling device and further to a second pulling device and then onto a reel, whereby the pulling devices subject the fibre to a desired amount of tensile stress, as a result of which the fibre breaks if a strength of the fibre is insufficient, and in which method in the case of a fibre break a first fibre end positioned after the break relative to the direction of motion is guided between the first and the second pulling device by a first channel section, which guides the first fibre end to the second pulling device, and after the second pulling device the first fibre end is guided into a second channel section which is off a normal fibre track and along which the first fibre end is guided into a scrap fibre processing system, and at a desired moment the fibre with the first fibre end is cut and a second fibre end positioned after the cut relative to the direction of motion is guided to the normal track, along which the second fibre end is guided onto a reel.
