Is it all over or just in a few places? A few places can be fixed by inserting a straight pin into the sandwich close to the beard and swishing the pin sideways to pull the beard back into the sandwich. If it is all over than one of the sweater de-fuzzers with the rotating blades may work. A sticky roller may just pull more of the batt fibers through rather than remove them. You will have to test to see which works best.
