Abstract

In a liftable window drape (10), such as a window shade with straight pleats or a curtain with rounded pleats, a fabric web (11) is employed which, on its rear side, has several parallel, vertical rows (16,17) of loops with guide elements. The latter can be produced by a folding band affixed to the rear side of the fabric web (11). The drawstring (21) is secured at the lower marginal region of the fabric web (11) and extends to a carrier (29) secured in the upper marginal region of the fabric web (11). In order to assure a satisfactory appearance of the window drape (10) and to easily adjust this to changing window heights, it is proposed to let the loops in the rows extend horizontally and to form each loop from a bundle of weft threads (24) which float over the fabric web (11) or over the folding band. A connector is threaded through at least two vertically spaced weft bundles (24) and guides these towards one another while the region of the fabric web therebetween is gathered to form a permanent horizontal pleat (44).

A window drape, comprising a web of flexible material having opposed first and second marginal portions, one of said marginal portions being mountable on a carrier to suspend said web with the other of said marginal portions below said one marginal portion;

at least one row of projecting bundles extending in a direction from said first to said second marginal portion on one side of said web;
said projecting bundles being spaced from one another when said web is flat, and each of said projecting bundles including a group of weft threads mounted on said web and projecting outwardly from said one side;
and a holding element engaging two of said projecting bundles in such a manner that the portion of said web intermediate said two projecting bundles defines a pleat in all positions of said web when said web is suspended, said holding element comprising a guide section for said line, said line extending through the guide section of each said holding element.
