Abstract
A weaving installation includes a loom that receives a series of strands, and at least one device for measuring the diameter of a strand having a defined number of filaments. The device includes a diaphragm having an external ring forming a support on which a series of strips forming an iris are fixed. The strips are movable and allow a substantially circular space with variable dimensions to be defined at the center of the iris. The diaphragm is configured to adjust the dimensions of the space so as to allow a strand of the loom to pass through it, and to encircle the profile of the strand so as to allow the number of filaments in the strand to be determined.
