Successive hollow polygonal bodies which are made of a ductile material and each of which has three corners and two straight open-ended terminal portions are converted into rectangular spacer frames for use between the panes of multiple pane windows by orienting the polygonal bodies in such a way that the terminal portions extend downwardly from their open ends, by admitting metered quantities of a flowable desiccant into selected parts of the two terminal portions, by converting one of the terminal portions into an L-shaped frame member with a section which is in register with the other terminal portion, and by inserting sealing plugs into the open ends of the two terminal portions.

A method of making a spacer frame for use between the panes of a multiple-pane window, comprising the steps of transforming an elongated hollow tubular blank of ductile material into a polygonal body with a plurality of corners and mutually inclined first and second terminal portions; introducing a flowable desiccant only into at least one of the terminal portions; thereupon converting the first terminal portion into a substantially L-shaped frame member having a first section extending from one of the corners, a second section abutting or adjacent said second terminal portion, and a corner between said sections; and establishing a seal between said second terminal portion and said second section. Apparatus for making a spacer frame for use between the panes of a multiple-pane window from a hollow polygonal body having a plurality of corners and mutually inclined first and second terminal portions each of which is adjacent a corner, comprising means for introducing a flowable desiccant into at least one of the terminal portions so as to only partially fill the at least one terminal portion; means for converting the first terminal portion into a substantially L-shaped frame member having a first section adjacent the respective corner, a second section abutting or adjacent the second terminal portion, and a corner between the first and second sections; and means for establishing a seal between the second terminal portion and the second section.
