ABSTRACT:
Method and apparatus for automatically packing goods which are fed continuously in series spaced a predetermined distance from each other by means of a continuously fed strip of a stretch film having self-adhering and resiliently stretchable natures. The strip is fed by conveyor clamping opposite sides edges of the strip along the direction of feeding of the goods from above the same obliquely downwardly to intersect the path of feeding of the goods so that the upper side and lateral sides of the respective goods are wrapped by the strip as the strip is being fed. After the upper and lateral sides of the respective goods are wrapped by the strip, the opposite longitudinal side edges are introduced into converging guide slots so that they are folded back upon the bottom side of the respective goods where they are joined adhered with each other to form a cylindrically shaped strip onto the bottom side of which the joined longitudinal edges are adhered. Then, the cylindrically shaped strip is severed at positions intermediate the portions in which the respective goods are wrapped to leave leading and trailing ear portions. The leading and trailing ear portions are folded back upon the bottom side of the severed cylindrically shaped strip section in which the goods is wrapped so as to be adhered thereto by ear portion capturing devices, respectively, which are moved relative to the feeding of the cylindrically shaped strip section.
