Gaf Glass Mat Splice Table Improvements, Grant Haug, Kevin Lansang, Ronald Lam, Michael Mooney
Mechanical Engineering
The GAF asphalt shingle production line in Shafter, CA requires continuous operation in order to maximize production efficiency. The assembly line process begins with feeding a large roll of fiberglass web into an accumulator. However, once the fiberglass roll approaches the end, it must be spliced with a new roll in order to maintain continuous feed into the production line. The splicing process must be fast and reliable to prevent any delay of the production line. Currently, this process is performed by two workers who manually feed the new fiberglass roll, align the two mats, cut the mats, apply glue …
