Water and gas proofing definite lengths of wiring - applying 2 layered tape having room temp. adhesive on side facing leads and heat-melting adhesive on outer layer

摘要

The wiring system with a number of leads (1) has a defined regim is made lonitudinally water and gas-tight by positioning the leads in a section of the wiring system on a double-layer strip. An inner layer (5) is then adhesive at room temp. An outer layer (6) is of hot-melt adhesive such that the wires are parallel to each other with their axes perpendicular to the longitudinal axis of the strip, in at least one layer over the periphery of a circular support of, e.g. polyurethane foam (3). A hose section (7) is passed over the section and is heat-shrunk over it. ADVANTAGE - Sections of more than 30-40 leads can be sealed without damage to insulation.
