Abstract
A device for feeding a liquid thread-treating medium to the thread in a double thread twisting machine has a wiping head of a wear-resistant material arranged in a housing and extending from below into an annular recess of the overflow plate and into the thread running plane. The wiping head has an opening in the top thereof which extends substantially parallel to the spindle axis and has an insert in the opening which induces a capillary action that transports the thread-treating medium from a supply pipeline to the upper port of the opening. The insert is a pin made of a rigid material and of noncylindrical cross section so that between the outer surface of the pin and the inner surface of the opening small gaps are formed which produce the capillary action.
