3. Web Guiding and Tension Control in Converting Industries

With its extensive sensing range (up to 1000mm) and line reflective capabilities, the LS-H22F is well-suited for monitoring the position and width of continuous webs (e.g., paper, film, textiles) in converting machinery. The line beam can span a segment of the web, making it robust against minor surface imperfections.

Problem Solved

Maintains consistent web alignment and tension, which is crucial for high-efficiency printing, coating, or slitting operations, thereby minimizing material waste and improving overall product quality.
