Elbows in tubular blanks which are filled with a desiccant are formed by clamping a blank at one side of the intended locus of the elbow, by bending the blank at the other side of the intended locus of the elbow relative to the clamped portion of the blank, by propping the blank in the region of the inner wall of the developing elbow, and by plasticizing the material of the blank in the region of the outer wall of the developing elbow so that the material of such outer wall is less likely to exhibit cracks and/or to burst as a result of bending of the blank.

A spacer for use in multiple-pane windows or the like, comprising an elongated member including an elbow and two sections flanking said elbow, said member having a tubular portion, a supply of desiccant at least partially filling said tubular portion, and two extensions extending laterally of said tubular portion, disposed in two substantially parallel planes and being spaced apart from one another, said extensions having outer sides which are adjacent the inner sides of two spaced-apart panes when the spacer is installed in a multiple-pane window and said tubular portion including two sidewalls having outer sides, the distance between the outer sides of said sidewalls being less than the distance between the outer sides of said extensions and each of said sidewalls being adjacent one of said planes and being integral with the respective extension.
