<p>The level winder device 100 includes a pair of spaced and opposed side walls 101, 102 connected by an elongate beam 103 and supported for rotation about axes parallel to the longitudinal axis of the beam 103 a pair of upper and lower elongate rollers 104, 105 to control the height at which a hose (not shown) is wound on or paid out relative to the spool 201. Mounted tor reciprocal linear travel along horizontal rails is a carriage 110 comprising a roller housing 41 and a pair of spaced short rollers mounted for rotation about a respective vertical axes. The short vertical rollers 106, 107 are adapted to control the pa> out and the winding on of the hose with regard to lateral placement on the spool 201 and are spaced sufficiently to permit the free passage of the hose defined by the gap between the vertical rollers 106, 107 and the horizontal rollers 104, 105.</p> |
