Abstract

332,132. Hoover, Ltd., (Assignees of Ballou, H. R.). March 18, 1929, [Convention date]. Paper and like bags.-Iu manufacturing bags from paper or like fibrous material, the paper is folded in longitudinal pleats C<2> and joined at C<3> to form a collapsable bag. To form a neck, two' sides are folded at H and bent over as shown in Fig. 13. The other end is closed by folding over at G and securing by means of a clip E as in Fig. 9. Other methods of closing are described in which eyelets, rivets, or stitching are employed. The neck of the bag may be strengthened by fitting a cuff C<4>. A further modification states that the paper may be folded into box-pleats.
