  • BLIND ASSEMBLY AND METHOD OF ATTACHING A SHADE MATERIAL TO A WINDING CORE OF A BLIND
    Publication number: 20150361717
    Abstract: Blind assembly comprising a shade material, a winding core and/or a bottom rail, and compensation means. The shade material is attached to the winding core and/or the bottom rail by attaching the compensation means to the shade material in a first condition in which the compensation means extend along a first line with a first shape. The compensation means can be attached to the winding core and/or the bottom rail in a second condition in which the first line has a second shape, different from the first shape. As a result, the shade material is loaded with compensation forces that can counteract any sagging forces exerted on the shade material by the sagging winding core and/or bottom rail.
