Methods for calibration and automatic alignment in friction drive apparatus










Image Number 6 for United States Patent #6637634.

A friction drive apparatus includes an edge detection system for determining a lateral position of a strip material advancing in a longitudinal direction. The edge detection system includes a first sensor and a second sensor for monitoring the lateral position of the strip material. The friction drive apparatus also includes instructions for automatically aligning the strip material as the strip material is advanced a predetermined aligning distance and instructions for calibrating the second sensor with respect to the first sensor to compensate for any potential discrepancies therebetween. The apparatus and methods of the present invention ensure that the strip material is properly aligned in the friction drive apparatus and limit waste of strip material during those operations.
