To provide for lubrication of a yarn guide follower element, adapted to ride in a spiral track formed on a cylindrical roller, a duct is bored through the follower, the duct communicating with lubricating openings at the bottom of the guide groove. The top of the duct is formed as an enlarged funnel, across which a stripper bar is mounted which reciprocates with the yarn guide follower, in the traverse movement of the yarn guide. A lubricant supply trough is located just above the stripper, formed with openings of such size that drops of lubricant form, therein. The drops are stripped off by the stripper element, to drop into the funnel shaped opening, be sucked into the duct and lubricate the bottom of the spiral groove. |
