Abstract: The invention relates to a sealing element to be applied when feeding at least one elongated object through a vacuum apparatus, the sealing element comprising a casing with a first detachable part having a projection on its underside that tapers from a first end of the casing to a second end of the casing and a second detachable part having a hollow portion that tapers from the first end of the casing to the second end. The projection fits in and partially fills the hollow portion creating a gap between the projection and the hollow portion. The second detachable part has a groove around a portion of its perimeter on an upper surface which contains a resilient sealing means that allows the first and second detachable parts to be sealed when abutted against one another.

Abstract: The invention relates to a steel substrate with metal coatings for the reinforcement of vulcanizable elastomers, as well as a method for the continuous manufacture of a thus coated substrate and elastomer objects reinforced with said substrate.The substrate is provided with a first coating and a second coating at least covering part of the first one and a bonding layer being present between the two said coatings. The second coating comprises e.g. cobalt that can be applied by plasma sputtering. The coating combination can be easily adapted to the specific elastomer compositions and the reinforcement requirements aimed at.
