Abstract
In apparatus 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 contacting stations after the first contacting station each include apparatus for 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 folding and contacting operations, and pressure may be applied to the conductor and tape after the tape has been completely fixed to the conductor.
