Abstract
A method of making an enclosed, hollow insulating spacer for spacing apart panes of a multiple pane unit. The method includes steps of forming metal into first and second leg members for a spacer, preheating the first and second leg members of the spacer near the melting point of one of a synthetic resin material and a composite synthetic resin material, feeding the preheated first and second leg members of the spacer into a crosshead extruder together with one of the resin materials to embed by crosshead extrusion only a portion of each of the first and second leg members into the material, to affix the embedded portion of each of the leg members to the material and to form from the material a first bridge member that extends between the leg members and spans across one end of each of the leg members, and providing a second bridge member that connects the opposite ends of the leg members. Thereby defined is an enclosed channel portion of an insulating spacer, which has a hollow interior, by a configuration of the first bridge member, the first and second leg members and the second bridge member.
