Abstract

186,773. Hartmann, C. W. Aug. 12, 1921. Paper bags, making.-Relates to a bag-making machine in which a web of paper is folded around a former into a flat tube that is cut up into bag lengths and gummed and folded, and comprises means for gumming and folding the bottom of the tube, means for stacking the finished bags, and arranging the parts of the machine so that a minimum space is occupied. In the construction shown, a web of paper from a roll, after being pasted along one edge, is folded around a former 10 into a tube which is cut into bag lengths by a blade 14. The short tube is fed by rolls 13 to the gumming device which consists of a rib or blade 19 secured at its end to a pinion 20 that engages a toothed segment 21. The pinion is journaled in a crankarm 22, Fig. 3, and the segment is secured to a crank 23. These cranks are oscillated in such a manner that the blade 19 is turned through 180‹ as it is swung from the paper tube to the feed-roller 18 of the gum box and thus does not make a wiping contact with either the paper or the feed-roller. After being gummed, the paper tube is forced by a reciprocating folding-blade 17 into the space between rollers 15, 16 which fold and press the bottom of the bag. The folded bag is conveyed to the delivery box by means of endless bands 26, 28, 31, Fig. 2, which are arranged mainly in two upright runs as shown in order to minimize the space occupied by the machine. The bands feed the bag between the side rails 33, 34 of the folding box, and an oscillating plate 38 knocks the bag from between the rails into the pile 37. The rails 34 engage the edges of the bag and prevent it from returning into the path of the succeeding bag.
