In order to determine whether the strands meet the required production and marketing standards, the weavers use measuring instruments.
This reel can produce hanks of up to one meter in length by turning the crank, which rings a bell for every 100 meters.
The length of the hank being known, it is then possible to determine the titre of the silk thread, i.e. its fineness (measured in deniers), by simply weighing it with a scale.
