Abstract

1,221,000. Packaging machines. MEAD CORP. 1 April, 1968 [14 Sept., 1967], No. 15662/68. Heading B8C. Reciprocable feeder means adjacent the path of movement of a plurality of articles engage the side of a blank to feed it towards and adjacent the path where blank advancing means move the blank in the same direction as the articles and out of the way of the feeder means, Blank folding means, on each side of the path, then immediately fold the blank about the article sides. In one embodiment, two suction cups 9, Fig. 1, on pivoted arms 10 engage the end blank B in a magazine 2 and carry it downwardly to a position adjacent a set of bottles A moving on a conveyer 8. Arms 38, 39 positioned on each side of the bottles, rotate clockwise to push the blank in the direction of movement of the bottles so that the suction cups can swing upwardly to engage the next blank. Fingers 42, 43 integral with the arms 38, 39 fold the blank about the bottle sides. In a further embodiment, arms (65, Fig. 3) oscillate to and fro about a pivot (66) to push the blank B clear of the suction cups (45). Arms (69), forming part of the linkage which oscillates the arms (65) carry fingers (79) which describe an elliptical orbit (80) to fold the blank down about the sides of the bottles. The blank may have apertures for receiving the necks of bottles or slits for receiving the corners of cans.
