ABSTRACT:
A fibrous work piece, e.g. a glass fiber mat or blanket, is simultaneously cut, sealed and encapsulated using a focused, high energy liquid jet containing a sealant. The sealant in the focused, high energy liquid jet is deposited on and seals the edges of the kerf formed by the cutting operation to encapsulate dust and short length fibers formed by the cutting of the fibrous work piece. The focused, high energy liquid jet is emitted from a nozzle and the sealant is introduced into and mixed with the liquid before the liquid exits the nozzle. Portions of the fibrous work piece can be compressed by hold down shoes or by one or more high pressure air streams directed onto the work piece adjacent where the work piece is being cut to facilitate the formation of a cleaner edge on the kerf being cut in the fibrous work piece.
