Abstract
A method of building and stretch wrapping loads of layers of load units that includes the steps of providing at least one layer of load units in a load building and wrapping area, applying horizontal compression to the at least one layer, subsequently applying vertical compression to the at least one layer while applying the horizontal compression, releasing the horizontal compression while retaining the vertical compression, rotating the at least one layer relative to a packaging material dispenser to apply packaging material around the at least one layer while retaining the vertical compression, and releasing the vertical compression.
Claims17
A method of building and stretch wrapping loads of layers of load units, the method comprising the steps of:
- providing at least one layer of load units in a load building and wrapping area;
- applying horizontal compression to the at least one layer;
- subsequently applying vertical compression to the at least one layer while applying the horizontal compression;
- releasing the horizontal compression while retaining the vertical compression;
- rotating the at least one layer relative to a packaging material dispenser to apply packaging material around the at least one layer while retaining the vertical compression;
- and
- releasing the vertical compression.
An apparatus for building and wrapping a load comprising:
- a packaging material dispenser for dispensing packaging material;
- means for providing relative rotation between the packaging material dispenser and the load in a load building and wrapping area for wrapping the packaging material around the load;
- a layer transporter for transporting load layers from the layer building area to the load building and wrapping area;
- a side compressor for applying horizontal compression to the load;
- a vertical compressor for applying vertical compression to the load;
- and
- a controller for actuating the side compressor, subsequently actuating the vertical compressor while continuing to actuate the side compressor, subsequently deactivating the side compressor while actuating the vertical compressor and the means for providing relative rotation to wrap packaging material around the load while continuing to actuate the vertical compressor, and subsequently deactivating the vertical compressor.
