Abstract
Abstract A patterned curtain panel is lengthwise pleated in symmetry with a pattern on the panel by providing hooking holes disposed symmetrically with the pattern in a heading strip along the top edge of the panel. Crosswise contraction of the panel automatically forms pleats in the same. By placing the hooking holes so that alternate wide and narrow lengthwise sections or strips of the panels are defined, crosswise contraction of the panel, for instance, by means of a pull string, causes the wide sections to be pleated while the narrow sections remain flat.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
179 words
A curtain comprising: a rectangular panel made of pliable material and including a repeat pattern in the form of a plurality of spaced apart rows of decorations extending parallel to two opposite edges of the panel; a heading strip incorporated in the panel material and extending parallel to a third edge of the panel across the width thereof, said heading strip including a plurality of lengthwise spaced hooking holes, each of said holes being disposed intermediate two adjacent rows of said decoration and grouped in alternate sections of different width; and pull means coacting with the hooking holes the length of said heading strip for crosswise contracting said panel, actuation of said pull means contracting the wide sections while leaving the narrow section substantially flat, contraction of the wide sections causing lengthwise pleating of the respective lengthwise panel portion, the spacing of the rows of decorations and the spacing of the hooking holes being so correlated that the decorations in the flat sections and on the pleats in the pleated sections are centered upon actuation of the pull means.
