Abstract

The present invention provides a sheet material mounting device having two channels, namely, a mounting channel for receivably engaging a rod for gripping the sheet material and a spacer channel for receivably engaging a spacer support configured to engage a lift cord and, optionally, a spacer cord. The spacer channel may be positioned above the mounting channel such that the center of gravity of the mounting device is located above the center of the mounting channel, thereby reducing asymmetric tilt of the sheet material engaged by the mounting channel and reducing friction against the lift cord. Alternatively, the mounting channel may be positioned above the spacer channel. The mounting channel and the spacer channel are preferably both C-shaped, and each channel has an opening which faces in a direction opposite the direction faced by the opening of the other channel. Thus, a side view of the mounting device may resemble either an 'S' or a reverse 'S'. In accordance with another aspect of the invention, there is provided an apparatus and method for assembling the components of a sheet material mounting device, such that the assembled components of each sheet material mounting device are capable of maintaining vertical alignment with respect to every other sheet material mounting device comprised by the window covering system. Moreover, there is provided an apparatus and method for adjusting and re-aligning assembled components of a sheet material gripping apparatus.
