Abstract
In method for application of a tape of insulating material provided with a heat fixing binder to a substantially elongated rectangular electrical conductor in the longitudinal direction thereof, the conductor is heated, a portion of the tape is contacted with the first side of the conductor and other portions of the tape are successively contacted with other respective sides of the conductor. The successive steps of contacting after the first contacting step each include a first step of folding a portion of the tape about an edge of the conductor and then contacting a portion of the tape with a side of the conductor including that edge. The conductor may be additionally heated after several steps of folding and contacting, and pressure may be applied to the conductor and tape after the tape has been completely fixed to the conductor.
