1 Automatic machines for wrapping with stretch film Customer benefits Characteristics Customer benefits Very robust and flexible machine frame in large-dimension steel profiles Fully automatic process: Film inserting, wrapping, roping, welding and cutting of the film end The pallet remains stationary while being spirally wrapped Wrapping can be started and finished at any height required Gentle wrapping without load edge pressing due to Power-pre-stretch system Slip ring system Display with clear text for program flow and malfunction indication Monitoring by photocells Suitable for various pallet and conveyor heights High performance No centrifugal forces High flexibility Specially suitable for lightweight and sensitive products Constant film tension Easy operation Optimal pallet positioning

Features Easy operation User-friendly control

that the fi lm end is consistently sealed with

Load stabilizer for very instable loads High

irregularly loaded pallets due to spirally

there are no centrifugal forces Top sheet

required Power-pre-stretch Pre-stretching of

Of aluminium, supported on polyurethane rollers

machine frame Very robust and fl exible machine

2 Features Easy operation User-friendly control panel Counter plate heat sealing device Ensures that the fi lm end is consistently sealed with no tail to provide a perfectly fi nished wrap Load stabilizer for very instable loads High performance Also with lightweight products and irregularly loaded pallets due to spirally wrapping while the pallet remains stationary there are no centrifugal forces Top sheet device When a splash or dust proof package is required Power-pre-stretch Pre-stretching of the fi lm up to 300% optimum utilization of the fi lm! Easy-Load-System (pat.) Rapid fi lm coil change Solid wrapping frame Of aluminium, supported on polyurethane rollers for silent and and smooth operation Steel machine frame Very robust and fl exible machine frame in largedimension steel profi les suitable for various pallet and conveyor heights
