Abstract
To prevent splatter of oil from a traverse spiral drum upon rapid rotation of the drum in high-speed spooling machines, an oil retention plate is provided extending parallel to the axis of the drum and having an oil wiping edge engaging the surface thereof, the drum being located in advance -- with respect to rotation of the drum -- of the position of the slider block engaged in a spiral groove of the rotating drum to provide for the traverse movement, the plate being of sufficient width to block spray of oil centrifugally thrown off the surface of the drum upon rotation thereof, a bead of oil being formed at the engagement edge of the drum and the plate, the bead penetrating the spiral groove in the drum to provide, due to the rotation of the drum, lubrication of the lateral surfaces of the groove and hence lubrication for the slider block while preventing contact of lubricating oil with the yarn being spooled.
