Abstract

A window shade sheet member formed from a material having the characteristics, with respect to strength, formability and shape retention, of plastic, and having a non-planar surface comprising raised portions and recessed portions is provided with one or more continuous cut lines, the penetration of which is so controlled that the contour of the cut which forms the cut-line substantially reflects the contour of the surface in which the cut is made, whereby the sheet member can be quickly and accurately sized to width at the time of installation by the final user, by separating the sheet material along a cut line. In a method of manufacturing said sheet member, the material is temporarily and locally flattened during the cutting operation by simultaneous application of pressing and stretching forces.
