Abstract
The present invention relates to a detector for measuring the characteristics of a linear product of very great length relative to its other dimensions, on a production machine or the like. The detector operates without contact with the linear product and is provided with at least one means (1) having zones (2 and 3) for measurement relative to a mean position of the moving filament (4) and measuring the variation of the complex morpho-dimensional and/or positional characteristics of the filament (4), this latter varying, either by vibrating movement, or by displacement induced by the mean position of the axis of movement. The invention is applicable to the field of the measurement of the characteristics of linear products of very great length.
