STRETCHED STRIPS FOR SPACER AND SEALED UNIT |
摘要 |
A spacer for a sealed unit is formed of a stretched elongate strip of material, such as metal. The elongate strip is longitudinally stretched, causing a reduction in the thickness of the material. Stretching is performed by applying a tension across a segment of an elongate strip. The tension can be applied to the elongate strip by passing the elongate strip through at least two spaced sets of rollers. A first set of rollers operating at a first speed engages with the elongate strip and a second set of rollers operating at a second speed applies a tension to the elongate strip to cause stretching of the material. Corrugated rollers can also be used to form the material into an undulating shape. |
