ABSTRACT:
The invention relates to process and apparatus for the automatic insertion of prefabricated box-shaped bags made of flexible packaging material into large box-shaped containers with a capacity of more than 100 liters. The bags are suspended on rolling carriages in such a way that two opposing sides are extended at the bag edge, the rolling carriage equipped in this way is transported to a transfer point where one side of the bag is received by a pulling device, and as a result of movement of the pulling device the bag is extended fully at its upper edge. Subsequently, the bag is received by a spreading device and introduced by way of the spreading device into a large container. The edges at the upper margin of the bag may be cut to form marginal side flaps for transfer into appropriate retaining devices on the large container.
