Abstract: A spool (10) filled with two or more elongated elements (14, 16) such as steel cords wound in parallel and in several windings upon the spool is provided. The distance s between two neighboring elongated elements, as measured along a line parallel to the axis (18) of the spool (10), is not more than 10 mm along 90 % of the length of each elongated element. The advantage is that unwinding problems such as sags and downstream processability problems are avoided.

Abstract: A steel cord (10) adapted for the reinforcement of elastomer products, comprises a core filament (12) with a core filament diameter and 3N layer filaments (14, 16) twisted around the core filament (12) in the same direction and with the same step. N ranges from four to five. The 3N layer filaments are arranged in an intermediate layer of N filaments (14) and in an outer layer of 2N filaments (16). The layer filaments (14) in the intermediate layer have an intermediate layer diameter. The core filament diameter is smaller than the intermediate layer diameter.

Abstract: A steel cord (38) comprises a first group and a second group. The second group is helically twisted around the first group with a cord twisting step. The first group comprises a first number of first steel filaments (10). The first number ranges between three and eight. The second group comprises a second number of second steel filaments (26). The second number is equal to or greater than the first number. The first filaments (10) having a twisting step greater than 300 mm. At least one of the second filaments (26) is polygonally preformed in order to allow rubber penetration.

Abstract: An elongation cord (10) adapted for the reinforcement of elastorner structures has a polymer core (12) and three to nine strands (14) twisted around the core with a cord twisting step in a cord twisting direction. At least one of the strands (14) has a first group (16) of filaments (17, 18) and a second group (20) of filaments (21, 22). The first group (16) of filaments (17, 18) is twisted with a first twisting step in a first twisting direction and the second group (20) of filaments (21, 22) is twisted with a second twisting step in a second twisting direction. The first twisting step is different from the second twisting step or the first twisting direction is different from the second twisting direction, or both. The first twisting direction is equal to the cord twisting direction and the first twisting step is equal to the cord twisting step.
