Abstract
Abstract A pleated fabric window covering for an angular top or ceiling wall has the pleated fabric upper part cut at the required angle and the pleat lines are cut from the angular edge inwardly a fixed distance forming tabs. The tabs are overlapped and stapled to the upper rail flat surface. Manipulation of control cords positions the pleated fabric at any desired location below the upper rail lower end.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
180 words
A method of making a pleated window covering having an extent of pleated material, a first rail interconnected with a lower edge of the pleated material for generally horizontal disposition and a second upper rail from which the pleated material hangs for arrangement with respect to a wall surface and oriented for disposition at a predetermined angle with respect to the horizontal, comprising the steps of: laying a length of pleated material onto a horizontal surface, with each pleat being defined by a pair of pleat lines; securing the first rail to a lower edge of the pleated material; forming a strip with outer and inner parallel sides on an upper surface of the pleated material, with said strip being arranged at the predetermined angle relative to a pleat line; severing the pleated material along the outer side of the strip; severing the pleated material along each pleat line from the outer side of the strip to the inner side of the strip thereby forming a plurality of tabs; and securing the tabs to one surface of the second rail.
Claim 2
Independent Claim
180 words
A method of making a pleated window covering having an extent of pleated material, a first rail interconnected with a lower edge of the pleated material for generally horizontal disposition and a second upper rail from which the pleated material hangs for arrangement with respect to a wall surface and oriented for disposition at a predetermined angle with respect to the horizontal, comprising the steps of: laying a length of pleated material onto a horizontal surface, with each pleat being defined by a pair of pleat lines; securing the first rail to a lower edge of the pleated material; forming a strip with outer and inner parallel sides on an upper surface of the pleated material, with said strip being arranged at the predetermined angle relative to a pleat line; severing the pleated material along the outer side of the strip; severing the pleated material along each pleat line from the outer side of the strip to the inner side of the strip thereby forming a plurality of tabs; and securing the tabs to one surface of the second rail.
Claim 3
Dependent Claim
32 words
A method as in claim 1, including the further step of forming the tabs into a sequence of overlapping adjacent pairs of tabs prior to securing the tabs to the second rail.
Claim 4
Dependent Claim
37 words
A method as in claim 1, in which the strip is formed by pressing a straight edge with parallel sides onto the pleated material and marking the pleated material along each of the straight edge parallel sides.
Claim 5
Dependent Claim
17 words
A method as in claim 1, in which severing of the pleated material is accomplished by cutting.
Claim 6
Dependent Claim
18 words
A method as in claim 1, in which the tabs are secured to the second rail by stapling.
