Abstract

132,079. Robinson, E. S. & A., and Duerden, S. Sept. 24, 1918. Paper bags, making. - Relates to flat-bottomed or satchel - shaped bags which are formed from one piece of material having infolded side gussets or tucks and a folded bottom closure extending practically straight across the width of the bag. In order to avoid the difficulties which attend the creasing of the finished bag when varying thicknesses of paper have to be acted on owing to the presence of the folded closing-flap, the diagonal and transverse creases d, h, Figs. 5 and 6, which facilitate the opening of the bag into its rectangular form are formed in the paper tube or web from which the bag is made before the blank is severed. The paper tube a, Fig. 1, is forwarded by rollers b, b<1> to a cutting-device c and the severed end passes forwards to rollers e, e<1>, f, f<1> which form the diagonal and transverse creases, after which the tube is severed at the required length and the end is pasted and folded. When the paper web is creased before being formed into a tube, the rollers for making the diagonal creases may be so arranged, Fig. 8, that the creases will occur only inside the gusset portion of the tube,
