Method and apparatus for waterproofing a wire harness

摘要

A plurality of electric wires of a wire harness have a filler applied to predetermined waterproofing portions thereof. A sheet is wound on a peripheral surface of a bundle of electric wires to which the filler has been applied, and the sheet-wound waterproofing portion is repeatedly pressed from opposite sides. By such pressing, a relative displacement of the electric wires and the filler can be accelerated and the filler can be spread and filled securely in the waterproofing portion.
