Abstract: A conversion station (300) comprising a mechanism (240) operable to support at least some portion of a web (250), a conversion device located above the mechanism (240), the conversion device operable to traverse a conversion zone (244) located below the conversion device to bring a cutting member into contact with the web (250) to convert the web (250) into one or more individual products (201A, 202A; 201B, 202B; 201C, 202C), an image capturing device (260) located above the mechanism (240) and adjacent to the conversion device but outside the conversion zone (244), the image capturing device (260) positioned at a non-perpendicular imaging angle (271) relative to a surface plane (270) of the web (250), the image capturing device (260) operable to capture image information (261, 263) by imaging the one or more features located on the web (250) while the features are positioned within the conversion zone (244), and a control system operable to align the web (250) within the conversion zone (244) based on the image information (261, 263).
