For weatherproofing/storage of pallet loads, or just for protection against dust, we can design the Top Sheet Dispenser to work with automatic Turntable wrapping system or rotary arm wrapping system. The dispenser spreads top sheets after pallet load is discharged from the Palletizer and enters the Top Sheet Dispenser. After covering the top sheet, the load is wrapped up so that it can be delivered to customer or storage room. The top sheet will protect the load from moisture and dirt.
