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.

Method of applying a tape of insulating material provided with a heat-fixing binder to a substantially elongated rectangular electrical conductor in the longitudinal direction thereof in apparatus comprising a series of successively positioned operating stations, comprising the steps of:

heating the conductor at a heating station to fix said binder upon contact of said tape with said conductor;
contacting a tape portion with a first conductor side at a contacting station subsequent to said step of heating to fix said tape portion to said conductor;
subsequently successively contacting in turn the respective other tape portions with at least two other respective adjacent conductor sides at successively positioned contacting stations;
and
conveying the conductor through said heating station, and conveying the conductor and tape through said contacting station, and said successively positioned contact stations.
