The semi-automatic wrapping machines with rotating platform allow lateral wrapping of the palletized load. The winding takes place by the combined action of the rotation of the load placed on the platform and the vertical sliding of the bobbin-carrying trolley along the support column. In this type of semi-automatic pallet wrapper, the pallet loading-unloading operations on the platform are carried out by an operator using a pallet truck, which accesses directly on the rotation platform thanks to the particular opening shape present on the latter.
