Method for the automated weaving of a woven structure (30) by means of a weaving machine (1), comprising the insertion of a weft thread during the opening of a shed of warp threads, and prior steps of optimization, by an optimization tool (20), of an objective function having a first member evaluating the balance of said warp threads during the shed opening, said balance of the warp threads being evaluated by differences in elongation between the warp threads of an upper opening (10a) of said shed, and of a lower opening (10b) of said shed, and a second member evaluating constraints specific to the weaving machine (1). This optimization comprises the determination of a set of opening parameters that, at least locally, minimize said objective function, and this set of opening parameters is used to set the parameters of the weaving machine (1).
A method for automated weaving (100) of a woven structure (30) using a weaving machine (1), comprising the insertion of a weft yarn during the opening of a shed of warp yarns, and prior steps (110, 120, 130) of optimizing an objective function having a first member evaluating a balance of said warp yarns during said shed opening, said balance of the warp yarns being evaluated by differences in elongation between the warp yarns of an upper opening (10a) of said shed, and of a lower opening (10b) of said shed, and a second member evaluating constraints specific to said weaving machine, said optimization comprising the determination of a set of opening parameters (43) minimizing, at least locally, said objective function, and said set of opening parameters being used to parameterize said weaving machine.
A weaving tool including a weaving machine (1) with a woven structure (30) adapted for inserting a weft yarn during the opening of a shed of warp yarns, and an tool (20) of optimizing an objective function having a first member evaluating a balance of said warp yarns during said shed opening, said balance of the warp yarns being evaluated by differences in elongation between the warp yarns of an upper opening (10a) of said shed, and of a lower opening (10b) of said shed, and a second member evaluating constraints specific to said weaving machine, said optimization comprising the determination of a set of opening parameters (43) minimizing, at least locally, said objective function, and said set of opening parameters being used to parameterize said weaving machine (1).
