Title
(EN) METHOD OF MAKING FABRIC VENETIAN BLINDS
(FR) PROCEDE DE FABRICATION DE STORES VENITIENS
Abstract
(EN)
In a method of making rolls or strips of material having no flaws except joints of supply of material, such as a roll of fabric is inspected for flaws. If any flaws are discovered portions of the material containing the flaws are cut away. The material is attached together after each portion is removed to create a joint for each reattachment. The portions that are cut away are sized so that the joints will be separated by a multiple of a selected distance from one another. The resulting material can then be fabricated into a panel of window covering material in which all the joints are co-linear along a perpendicular to the surface of the material. The joints are positioned so that they will be on a cut line for subsequent processing. In one embodiment the material is wound into a tubular structure that is cut along the joints to form a panel of window covering material.

La présente invention concerne un procédé de fabrication de rouleaux ou de bandes de matière sans défauts présentant néanmoins des joints de matière supplémentaire, telle qu'un rouleau de tissu, ayant subi un contrôle pour détecter les défauts. Si des défauts sont détectés sur certaines parties de la matière, les parties de matière comportant des défauts sont coupées. La matière est réunie après élimination de chaque partie de matière, de façon à créer un joint pour chaque nouveau raccord. Les parties coupées sont dimensionnées pour que les joints soient séparés les uns des autres par un multiple d'une distance sélectionnée. On peut alors utiliser la matière obtenue pour constituer un couvre-fenêtre pour panneau fenêtre, dans lequel tous les joints sont co-alignés perpendiculairement à la surface du matériau. Les joints sont placés de façon à ce qu'ils se situent sur une ligne de coupure, en vue d'un traitement ultérieure. Dans un des modes de réalisation, la matière est enroulée pour former une structure tubulaire découpée le long des joints et constituer ainsi un couvre-fenêtre pour panneau.
