Abstract

Disclosed is a creel including a plurality of creel bobbins, a plurality of guiding tubes located at the lower end of the creel and a plurality of guiding tubes located at the upper end of the creel, wherein each guiding tube is arranged for receiving a wire from an individual creel bobbin, wherein the lower half of the creel bobbins are arranged to feed their wires to the guiding tubes at the upper end of the creel, while the upper half of the creel bobbins are arranged to feed their wires to the guiding tubes at the lower end of the creel.

First claim

The invention claimed is:

1. A creel comprising a plurality of creel bobbins, a plurality of guiding tubes located at the lower end of the creel and a plurality of guiding tubes located at the upper end of the creel, wherein each guiding tube is arranged for receiving a wire from an individual creel bobbin, wherein the lower half of the creel bobbins are arranged to feed their wires to the guiding tubes at the upper end of the creel, while the upper half of the creel bobbins are arranged to feed their wires to the guiding tubes at the lower end of the creel.

2. The creel according to claim 1 , wherein, for each guiding tube receiving a wire from said individual creel bobbin, the wire in use extends from the creel bobbin towards the guiding tube at a fleet angle with respect to an imaginary center line normal to the axial direction of the creel bobbin, wherein the wire extends at a maximum fleet angle when the wire is unwinding from the extreme left and the extreme right of the creel bobbin, wherein the creel bobbin has a bobbin width and a minimum distance between the circumference of the creel bobbin and the guiding tube, wherein the bobbin width and the minimum distance are chosen such that the maximum fleet angle is less than ten degrees.

3. The creel according to claim 2 , wherein the maximum fleet angle is less than five degrees or less than three degrees.

4. A method using the creel according to claim 1 , wherein the method comprises the steps of:
feeding the wires of the lower half of the creel bobbins to the guiding tubes at the upper end of the creel; and
feeding the wires of the upper half of the creel bobbins to the guiding tubes at the lower end of the creel.
