An apparatus and method for minimizing entanglement and bunching of a retracting or extending cable (10, 11) for a swimming pool cover, comprises a shaft (4) with a roller (5, 6) to guide the cable. The roller slidably rotates on the shaft so that it rotates and moves axially in response to any forces provided by the cable when being retracted or extended, to minimize entanglement and bunching. |
