creel bobbin brake according to claim 1, wherein the strap body and the opening taper from the first end towards the second end at a taper angle which is the same for both the strap body and the opening. ### Claim 8 (depends on 1) The first creel bobbin brake according to claim 1, wherein the strap body is symmetrical in a lateral direction perpendicular to the longitudinal direction of the strap body. ### Claim 9 (depends on 1) The first creel bobbin brake according to claim 1, wherein the first inner edge and the second inner edge are parallel to the first outer edge and the second outer edge, respectively. ### Claim 10 (depends on 1) The first creel bobbin brake according to claim 1, wherein the first outer edge, the second outer edge, the first inner edge and the second inner edge taper inwards in a lateral direction perpendicular to the longitudinal direction over each revolution with a pitch distance, wherein the distance between the first outer edge and the first inner edge and the distance between the second outer edge and the second inner edge in said lateral direction is equal to or smaller than the pitch distance. ### Claim 11 (depends on 1) The first creel bobbin brake according to claim 1, wherein the strap body is made from a single piece of material. ### Claim 12 (depends on 1) The first creel bobbin brake according claim 1, wherein the strap body comprises reinforced synthetic resin or rubber based material. ### Claim 13 (depends on 1) The first creel bobbin brake according to claim 1, wherein the strap body comprises leather. ### Claim 14 (depends on 1) The creel bobbin assembly comprising the first creel bobbin brake according to claim 1, wherein the creel bobbin assembly further comprises a first shaft for supporting a first creel bobbin and a base member for supporting said first shaft with respect to a creel plane, wherein the first shaft is provided with a brake surface, wherein the strap of the first creel bobbin brake is arranged to be wound around said brake surface over the at least two revolutions. ### Claim 15 (depends on 14) The creel bobbin assembly according to claim 14, wherein the brake surface has a circumference, wherein the opening in the strap body has a length in the longitudinal direction of the strap body that is equal to or larger than two times the circumference of the brake surface. ### Claim 16 (depends on 14) The creel bobbin assembly according to claim 14, wherein the brake surface is formed by a brake drum that is rotationally fixed to the at least one shaft. ### Claim 17 (depends on 14) A creel comprising a plurality of creel bobbin assemblies according to claim 14 and further comprising a plurality of creel bobbins, a plurality of guiding tubes located at a lower end of the creel and a plurality of guiding tubes located at an upper end of the creel, wherein each guiding tube is arranged for receiving a wire from an individual creel bobbin, wherein a lower half of the creel bobbins are arranged to feed their wires to the guiding tubes at the upper end of the creel, while an upper half of the creel bobbins are arranged to feed their wires to the guiding tubes at
