Abstract: A method of integrating a plurality of wires (40) of an electrical round cable (4) provides a jig (1) comprising an upper block (3) and a lower block (2). The lower block has a jig plane (20) in which a plurality of receiving grooves (22) is defined. The wires of the round cable are placed into the receiving grooves of the lower block. An adhesive strip (5) is placed onto insulative sheaths of the wires. The upper block is moved downwardly to depress the adhesive strip against the insulative sheaths. Simultaneously, the adhesive strip is heated so that it partly melts and integrally joins with the insulative sheaths.
