Abstract:
A method for forming stable stacks of intrinsically unstable objects as mutually superimposed layers in contact with each other which comprisesdepositing objects in a substantially horizontal plane to form an individual layer,wrapping the layer just formed with a band extending endlessly about the lateral surface of the layer, said band being of relatively yieldable and hand-tearable plastic film having a width not greater than the height of the individual layer, andforming additional layers to create a stack, by depositing objects onto and in contact with the preceding layer as soon as the preceding layer has been bound by said endless band or while the wrapping is taking place, each band wrapped around each layer being independent of bands wrapped around other layers, wherein substantially vertical rods are positioned at the corners of the layer of objects, said rods being wrapped when said layer is wrapped, and vertically removing said rods from the band, to leave the band extending around the layer of objects.
