ABSTRACT:
A level wind spooling device has a housing with lateral end walls, top, bottom, front and back walls forming a lubrication chamber. A spooling shaft journaled in the end walls is adapted to be connected to a rotary drive and has a cam track formed on the surface thereof and a cam track follower is engageable with the cam track and operatively moves the cam track follower back and forth along a linear path. An arm secured to the follower and passing through a slot in the housing and a flexible strand guide is secured to the arm means. Metal-to-metal sliding action is eliminated and thus reducing wear, oil contamination from metal particles and heat generation and is more efficient. The spooling shaft is lower in the oil housing to allow the spooling shaft to be more completely immersed in oil for better lubication of all internal components. The carriage follower assembly utilizes two roller bearing sets on the lower surface of the follower assembly guided by two steel guide bars on the bottom wall. There are no sliding metal-to-metal surfaces and all internal and external forces which tend to distort or damage the spooling shaft are eliminated. This arrangement results in a thinner level winding device having greater life and a higher efficiency.
