Their medium frame case erector bottom sealer utilizes a horizontal
erecting method to create a square case. The hopper has a standard
two-stack capacity, and is infinitely increasable to ensure there is no
downtime when adding knockdown cases. Cases are erected, bottom flaps
are folded quickly and securely sealed, and the case enters the
compression section before exiting the machine. After the cases are
filled, they can be fed into the FOL case sealer where the top flaps
are automatically folded and sealed.
