Abstract (en)

[origin: EP0942087A2] In the production of blinds, the separate material sections (2) are produced in the required shape in a coherent fabric web (1), with an edge zone (12) to manipulate it. Separation channels (13) are worked into the material web (1) between the edge zone (12) and the edge of the material section (2) and between the material sections (2), for them to be detached from the web (1). A number of material sections (2) are formed in the material web, next to each other. The edge (21) of the material section (2) is worked into a firm bond, by the yarn structure or an applied reinforcement. The edge (21) of the material section (2) has a yarn with a lower melting point than the surrounding fabric, to be separated by heat and the fused yarn material strengthens the edge (21) of the material section. A separation row is in the channels (13) between the material sections (2), using a yarn which dissolves during subsequent fabric treatment to separate the fabric sections (2) from each other and/or the edge zone (12) of the fabric (1). The fabric sections can be worked to include a tubular pocket, to take a stiffening or guide rod along its width and/or length, at the start or end of the fabric section. The pocket can be curved, and the ends of the pocket are secured by a locking edge. Before the fabric is coated, the fabric web is hot ironed, at least at the pocket zones. The fabric web is of texturized fiber or filament material, at least at the pocket zones. The pockets have one or more interruptions and are produced using the fabric warps, without the wefts. An indent at the rod takes part of the pocket with the bonded edge, to fix the front rod in place, with an elastic clamp which closes the indent. Eyelets are worked in the edges (21) of the fabric sections (2), for blind holders, and blind mounting ribbons are worked along extensions of the section edges (21). Reinforcements are worked into the material at the mounting points. The fabric web (1) is produced on a warp knitter, with selected needles working the fabric section edges (21) and an additional weft at the edges (21). The fabric (1) can also be produced on a loom, with denser warps at the section edges (21), taken from the adjacent zones to form the separation channels (13). An Independent claim is also included for a roller blind rod, with an indent along its length, with projections at the opening into the indent. Preferred features: The fabric lock has a central recess, for compression on insertion between the projections at the indent opening. The body of the lock has a central opening to allow the body to spread outwards.
