Abstract
The invention deals with problems arising in lubrication of the helical cam grooves of cam drums used in thread traversing mechanisms of winding machines. The drum is provided with an internal space acting as a lubricant reservoir. A passage extends between the space and the groove so that centrifugal force urges lubricant outwardly along the passage from the space towards the groove. Flow along the passage is controlled by a porous sintered metal body which permits a desired degree of a given lubricant to pass along the passage at a given rotational speed.
