Abstract
An apparatus which facilitates the raising and lowering of a pull-up band for a blind. An axially rotatable winding shaft is disposed generally parallel to the section rail by which the apparatus is attached to a wall. At least one winding roller is disposed along the winding shaft, having an axis of rotation extending generally horizontally and perpendicular to the winding shaft, and is adapted to extend and retract a pull-up band wound onto the winding roller responsive to a drive mechanism which transfers motion from the winding shaft to the winding roller. The winding roller is rotatably mounted in a holder, and the drive mechanism is housed in a housing which is detachably fastened to the section rail.
