ABSTRACT:
A method and apparatus for manufacturing individual plates from a mineral wool mat while minimizing the spread of loose fibers. The method comprises the steps of cutting the mat into individual plates, forming the plates into a pile, establishing a region of vacuum for exhausting air from areas adjacent the sides of the pile and causing movement between the pile and the vacuum to vacuum the sides of the pile. The apparatus for performing the method includes a cutting device for cutting the mat into individual plates, a stacking device for combining the cut plates into a pile of plates, a vacuum device positioned to establish a vacuum for withdrawing air and loose fibers from the sides of the pile, and a conveyor for causing relative movement between the pile and the vacuum device.
