An embedment device (20) for use in a structural panel production line (10) wherein a slurry (16) is transported on a moving carrier (14) relative to a support frame (12), and chopped fibers (18) aredeposited upon the slurry (16), includes a first elongate shaft (22) secured to the support frame (12) and having a first plurality of axially spaced disks (32), a second elongate shaft (24) secured tothe support frame (12) and having a second plurality of axially spaced disks (32), the first shaft (22) being disposed relative to the second shaft (24) so that the disks (32) intermesh with each oth er. The intermeshing relationship enhances embedment of the fibers (18) into the slurry (16) and also prevents clogging of the device by prematurely set slurry particles.
