Automatic Rotary Arm stretch wrapper RAS100
The conveyor moves the pallet below the rotary arm. The device for applying top cover moves downward to the level of pallet, unreels and cuts the top cover material. The film is applied and the device returns to its initial position. The stabilizer plate descends until it is in contact with the load. The fastening of the film is automatically carried out by an arm. The rotary arm starts to apply the plastic film around the pallet. The reel-holder carriage moves regularly upwards so that the pallet is spirally wrapped.
The automatic rotary arm pallet wrapping machine is controlled by PLC system, including main engine, rotate arm, film carriage, conveyor, guard rails and control panel.The rotate arm can work around the loads by working operation, easy to load and unload. When the load is put on the conveyor, it will be moved automatically to the wrapping station, and then the arm begins to rotary automatically. After wrapping, the load is moving to the next station.

On the upper part of the pallet the edges of the top cover are integrated into the wrapping. Depending on the selected program the wrapping may be continued during the downward movement of the reel-holder carriage. The sealing arm seals the extremity of the film on the pallet wrapping and cuts it. The stabilizer plate is lifted and the pallet removed.
