Four production lines—401, 402, 403, and 405—were located in the center portion of the southern half of
the plant. Production line 416 was located near the west wall (Figure 1). The production lines included
material feeders, separating and mixing machines, curing ovens, and trimming equipment connected by
conveyors. Lines 401, 402, and 403 were adjacent to each other; line 405 was approximately 80 feet east
of line 403. The open area between lines 403 and 405 was used to store racks of semi-cured acoustical
insulation, referred to as “pelts.” The molding department, where hydraulic molding presses and water jet
cutters were used to shape and size the automotive insulation products, was located in the northeast
quadrant of the plant.
