Abstract
A movable retaining wall is used in a first position in a compression baler to retain a compressed mass, such as microfibers, and is then moved to a second position into an opening in a wall of a packaging chamber filling the opening such that a gap between the edges of the interior surface of the retaining wall and the edges of the opening is too small to allow the compressed material to enter the gap when it passes through the packaging chamber and past the gap. To accomplish this requires the use of hidden hinges to guide the retaining wall as it moves from the first position to the second position and back to the first position. The hidden hinges allow the retaining wall to move essentially straight out of the opening in the wall of the packaging chamber before it begins to pivot towards the second position, thus allowing the tight fit. This feature prevents damage to the material being packaged since if it enters a gap while compressed, agglomerates will be formed when the compressed mass is moved through the apparatus which agglomerates cause processing problems and product defects.
