DRIVE UNIT FOR A CONVEYOR OF THE TUBE-ENCASED CABLE TYPE WITHSPACED-APART CONVEYING ELEMENTS FOR MATERIALS OF FLUID BEHAVIORABSTRACT OF THE DISCLOSUREA drive unit for distribution systems for materials of fluidbehaviour, such as livestock feed materials, in which a cableprovided with spaced-apart conveying elements is caused to slideinside a tube, said drive unit being of the type comprising ageared motor, on the output shaft of which there is fixed a toothedwheel about which said cable winds.The geared motor is mounted on a supporting structure in afreely oscillating manner such that as the tension in the slackbranch of the cable varies, the position of the axis of saidtoothed wheel varies by virtue of its rotation about an axis passingessentially through the point of tangency between the toothed wheeland the taut branch of the cable.
