ABSTRACT:
Fiber glass insulation batts are packaged by delivering them to the bottom of a stack of batts, then compressing the stack with a compression plate or platen. The compressed stack is pushed by the platen against a web of packaging film and into a hopper. The web adjacent one side of the stack is then moved over the top face of the stack to enclose it, and is heat welded to the web adjacent the other side of the stack. The web is severed intermediate the weld to separate the package from the web, leaving only a single weld in the package. The stack can be compressed by a dished platen to concentrate the greatest platen pressure at the periphery to avoid damaging the major portion of the surface of the batt contacted by the platen.
