The KL pallet wrapper/shrink line from Kurt Lachenmeier (Unna, Germany) can wrap up to 300 pallet loads/hr. Loads are passed though a "curtain" of flat film, then vertical sealing beams move together behind the load to produce a tight sleeve.
Film is sealed and cut then the load is moved to a shrink station. The machine holds two rolls of film at a time. They're automatically spliced together when one is empty.
