Abstract
A skew adjustment mechanism is used for adjusting the length of a lift cord on a window covering. The lift cord extends from a lift spool at a first end to an anchor drum at a second end. A cord wrap post is provided between the lift spool and the anchor drum so that the lift cord can be wrapped around the cord wrap post to provide friction between the lift cord and the cord wrap post when the lift cord is taut in order to reduce the amount of holding force that is needed to prevent the anchor drum from rotating.

A method for adjusting the skew of a covering including a rail, a cord wrap post, a lift cord extending from the rail and being wrapped around the cord wrap post, and a skew adjustment mechanism coupled to the lift cord, said method comprising:
- relieving a cord tension on the lift cord to reduce an amount of friction provided between the lift cord and the cord wrap post;
- adjusting an orientation of the rail using the skew adjustment mechanism while the cord tension on the lift cord is relieved;
- and
- reestablishing the cord tension on the lift cord to increase the amount of friction provided between the lift cord and the cord wrap post.
A method for assembling a covering including rail, a lift spool, a lift cord, a cord wrap post, and a skew adjustment mechanism, said method comprising:
- coupling a first portion of the lift cord to the lift spool;
- wrapping the lift cord at least once around the cord wrap post;
- coupling a second portion of the lift cord to the skew adjustment mechanism, the lift cord being wrapped around the cord wrap post at a location along a cord path of the lift cord defined between the lift spool and the skew adjustment mechanism;
- and
- selectively adjusting the skew adjustment mechanism to adjust an orientation of the rail.
