ABSTRACT:
A machine and process is provided for sinuously folding a batt of bulky non-woven fibrous material such as glass fiber and inserting the folded batt into a container such as a bag. The machine has a support table having first and second sections separated by an intermediate section, and the intermediate section has a first series of stationary, transversely extending rotatable rollers arranged along it, and a second series of movable, transversely extending rotatable rollers supported by vertically movable mountings which allow the movable rollers to be moved from an initial raised position, in which they are raised above and separated by a gap from the stationary rollers, to a lowered position in which they are below the stationary rollers so that the stationary and movable rollers are over-lapped. Means are provided for pulling the batt along the support table when the movable rollers are in the raised position, so that the batt extends between the stationary and movable rollers and along the first and second sections of the support table, and means are provided for sequentially lowering the movable rollers starting with those closest to the center of the batt so as to form the batt into sinuous curves. A copaction chamber is provided alongside the intermediate section and a plate is provided for pushing the folded batt into the compaction chamber. The compaction chamber has a spout onto which a bag can be fitted, and has a piston movable to compact and push the folded batt through the spout and into the bag.
