Abstract: This invention relates to an improved device for measuring the length of yarn absorbed by a textile machine, comprising in known manner a rotating member driven by the yarn during displacement thereof. It presents three fixed guides over which the yarn passes and which are positioned near the rotating member so that the yarn is in contact with the rotating member along two substantially equal arcs of low value, for example from 20.degree. to 50.degree. and advantageously 30.degree.. The device is more particularly applicable to measuring the length of yarn absorbed per stitch on flat knitting machines.

Abstract: The method comprises the steps of impregnating spooled threads with a cold treatment liquid inside a kier, leaving an air cushion above the liquid inside the kier, discharging the liquid from the kier through a liquid discharge outlet by feeding steam above the air cushion, stopping the discharge when the steam reaches the liquid discharge outlet, and treating the spooled threads with steam inside the kier.
