A drive motor is individual to each thrust member for rotating each thrust member to move the flexible lip toward or away from the other lip. A universal joint directly connects an output shaft of each motor to its respective thrust member. The output shafts are at oblique angles to their respective thrust members and some of the output shafts are disposed at substantial angles to others of the output shafts, whereby the motors are staggered. |
