Sealing PUR foam components on conductor bundles, comprises spreading the bundle at the point where the foam is injected, so it enters intermediate spaces

摘要

A process for sealing PUR foam components on conductor bundles (3), comprises spreading the bundle at the point where the foam is injected so the foam is pushed through the bundle. The foam passes through the intermediate spaces between the conductors, as well as over the outer circumference, so the intermediate spaces are also sealed.
