ABSTRACT:
A method is disclosed for forming longitudinally watertight sealed portions in a cable bundle comprising a plurality of cable strands which employs a composite adhesive strip having at least two layers, a first layer consisting of a mass having good adhesive properties at ambient temperature, and a second layer consisting of a melt adhesive. At the location of the portion to be sealed, the layer of the composite adhesive strip having good adhesive properties at ambient temperature is adhesively secured to the spread-out cable strands of the cable bundle to be sealed. After winding the cable strand layer provided with the composite adhesive strip upon itself or folding it together, an outer heat-shrinkable material (hose or sheet material) is applied about the portion to be sealed. A heat treatment is applied for causing the outer shrinkable material to shrink and the melt adhesive to swell between the cable strands themselves and between the cable strands and the outer heat-shrinkable material are filled with a plastic material.
