A system and corresponding method are disclosed for blowing or spraying loose-fill insulation (e.g. fiberglass) into wall cavities and the like the system, including a fiber recovery or recycling subsystem that vacuums up overspray or waste fibers and forwards them back toward the hopper. A fiber collector device having a fiber inlet and outlet is mounted above the hopper and, receives the recovered waste fibers and utilizes a baffle system to redistribute the recovered fibers back into the hopper so that they mix with virgin fibers therein. The mix of recovered and virgin fibers is then blown through the blow hose toward a wall cavity or the like to be insulated.

Why it's free to use
- Filed January 6, 1998 and granted June 11, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 6, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 6, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
