ABSTRACT:
TECHNICAL FIELD
The invention relates to an arrangement in connection with a fibre process, the arrangement being provided with control and drawing means for guiding a fibre or the like along a desired course, and with cutting means for cutting the fibre or the like at a moment dependent on the fibre process.
BACKGROUND
Arrangements like this are today known particularly in connection with methods of cabling optical fibres, in which the setting times in connection with a change of product are to be rendered as short as possible. The previously known solutions are based on arrangements in which the fibres are arranged to pass through a drawing apparatus, and a cutting apparatus cutting the fibre at a desired moment is connected to the drawing apparatus, more particularly after the drawing apparatus in the travel direction of fibre.
A drawback of the previously known solutions is that, for example, after the cutting the free head of the fibre runs, as it were, from the drawing means, for example to a waste receptacle, whereby fibre is wasted until the fibre line has been stopped. The amount of wasted fibre can be quite large, for line speeds can be hundreds of meters a minute. Further, the solutions are sometimes complicated, for particularly at high speeds it can be difficult to control the free head of the fibre and guide it to the waste receptacle.
SUMMARY OF THE INVENTION
The object of the invention is to provide an arrangement by which the drawbacks of the prior art can be eliminated. The object is achieved with the arrangement of the invention, which is characterized in that the cutting means comprise a body of revolution consisting of two parts between which the fibre or the like is arranged to pass during the process without that it comes in contact with the parts; that the body of revolution is arranged to rotate during the cutting of the fibre or the like about an axis that is essentially transverse to the travel direction of the fibre; that the edge of one part of the body of revolution is rendered so sharp that when the rotating motion of the body of revolution makes the edge press against the fibre or the like, the edge cuts the fibre; and that the free end of the fibre or the like is arranged to wind round the rotating body of revolution.
The main advantage of the invention is that the fibre can be cut in the middle of the process so that no fibre loss occurs. In mechanical proof testing, for example, the invention makes it possible to catch the free end of the fibre during deceleration. Another advantage is that the arrangement is not in contact with the fibres during the process, and that the fibres are cut, the free end is caught and the fibre line is driven down in one step. Yet another advantage of the invention is its simplicity, as a result of which it is cost-effective to use and introduce into use.
In the following the invention will be described in greater detail with reference to preferred embodiments illustrated in the attached drawings.
