Abstract

An apparatus for the installation of a defroster of the resistive type on the rear window of a completely assembled motor vehicle. The defroster comprises heating conductors in the form of thin pre-glued strips of solid copper or copper alloy applied to the inside surface of the rear window in a first direction with two spaced apart connecting conductors in the traverse direction. The apparatus is used for applying the various parallel heating conductors to the inside surface of the window. It comprises a guide member temporarily retained against the inside surface of the rear window, and a carrier having a head which receives and applies the strips of pre-glued copper conductor to the rear window, a base adapted to roll along the guiding edge defined by the guide member, and an upright shaft for supporting the head affixed, adjustable distance away from the base. The head is free to rotate around the axis of the shaft at least within limits, and it is also pivotable about an axis which is perpendicular to the shaft and parallel to the window engaging member of the head.
