  • Publication number: 20050139706
    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.

  • Patent number: 6889852
    Abstract: A layered filtering structure (10) comprises at least a first layer (12) and a second layer (13). Each layer comprises a web of metal fibers which has been sintered. The two layers (12, 13) are in contact with each other. The first layer, most close to the filter inlet side has a porosity below 55%, and the second layer, closer to the filter outlet side has a porosity which is at least 20% greater than the porosity of the first layer. The first layer is compacted in a separate manufacturing step. The layered filtering structure combines the advantage of a small filter rating with a low pressure drop.
