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.
