ABSTRACT:
An improved hand-held flat conductor applying apparatus for applying to the receiving surface of a glass pane such as the rear window in a motor vehicle, a plurality of equidistant essentially straight lengths of pre-glued flat conductor for defining the heating lines of a rear window resistive defroster. The apparatus uses a confining guide edge of predetermined configuration for setting a datum or base line for the heating lines, a translation carrier mounted to the confining guide edge and confined thereto except for translation therealong, a rigid bar secured to the translation carrier through a suitable pivotable foot and locking means therefore, and a conductor laying head supported to the rigid bar and positioned at anyone of a plurality of predetermined points along the rigid bar. The translation carrier is mounted to the confining guide edge by means of two widely spaced apart pairs of rollers which are suitably offset to prevent binding of the translation carrier when moving along the guide edge, and the guide edge is configured so as to present a flat main body having a top edge, and a T-shaped flange extending along the top edge and adapted to receive, on either sides thereof, the carrier rollers. The conductor laying head is of simple construction using a single pressure roller in the region of a glass engaging crescent which is nearest the receiving surface of the glass pane, and the mounting means for the conductor laying head relative to the rigid bar is such as to prevent rotation of the head about the axis of the rigid bar.
