IMPROVEMENT INPAPER BAGS AND Moozs 0F MAKING TH; SAM
Specification forming part ofLeiters Patent No. 146,271, dated Januaryo, I874 application filed November To all whom it may concern:
Be it known that I, CHARLES T. PAOKER, of the city and county of Philadelphia, State of Pennsylvania, have invented an Improved Paper Bag and Mode of Making the Same, of which the following is a specification:
My invention relates to the manufacture of that class of paper bags which are known as satchel or square bottomed bags; and the object of my invention is to so make bags of this class that comparatively simple machinery can be used in their manufacture-an object which I attain by uniting two strips of paper in the manner shown in the perspective view, Figure 1, of the accompanying drawing, and by closing one end of the united strips.
The precise construction of my improved bag will be best understood by describing the process of manufacturing the same, as illustrated in the diagram, Fig. 2, in which A and of which turn in suitable bearings. The upper paper a is conducted from the roll A beand the lower paper a is conducted over the pasting-roller G, and thence beneath the roller 1). The pastingroller is so constructed as to impart to. theunder side of the lower paper a two layers of paste, e a, one at each edge, as shown in 3, which represents an enlarged transverse section of the two strips of paper. The roller D is so rounded as to bend both strips of paper transversely, the upper strip being bent downward at its opposite edges, and the lower strip upward, as shown by the dotted lines a: m in Fig. 3. From the roller D the strips of paper are continued through yokes ff, which fold the bent portions of the upper strip down across the edge and beneath a thin blade or former, m,and the bent portions of the lower strip upward across the edges of, and over, a similar thin blade, 42, as shown in Fig. 4.
The above-described operations are, as regards the pasting, bending, and folding, similar to those conducted in ordinary paper-bag machines, as, for instance, in the machine for which Letters Patent were granted to S. E.
Pettee, May 5,1863, in which, however, a continuous single strip of paper is pasted, bent transversely, and formed into a continuous tube over a thin blade, whereas, in conducting my process, two strips of paper and two blades or formers, one for each strip,are used.
The two strips, after passing through the yoke f, in the condition shown in Fig. 4, are pasted together and thus intimately united at the points 3 y by. the usual drawing-rolls, which drag the strips from the rolls, and present the united strips or tube to the holdin g-rolls, while suitable lengths for bags are severed fromthe tube, and one end of each length pasted and folded, so as to close thebag at one end, the devices for accomplishing these duties being similar to those fOlllld. in the aforesaid patent of S. ErPettee, and in other paper-bag machines. two strips of paper will be the bag, Fig. 1, with V-shaped or satchel folds at its opposite edges. On filling the bag it will be distended to the shape shown in Fig. 5, the V-shaped folds being bent outward, so as to form the opposite edges to and a of the bag, and the closed bottom of the latter assuming a quad rangular form, and the said bottom having on the inside of the bag the angular folds or creases shown in Fig. 6, and the pasted joints y y projecting inwardly, as shown, in the said figure. Paper of a comparatively stiff character will resist, to a greater or less extent, this tendency of the bag to assume the desired form when filled, the folded bottom especially, owing to the stifl'ncss imparted to it, being an obstinate impediment to the proper distension of the bag. In order toobviate this difliculty,
I crease the bag at such points that the creases shown in Fig. 1 to that seen in Fig. 5. These creases may be readily made by appliances connected with the machine, or they may be OFFICE PENNSYLVANIA, assrenon 'ro' The result of these operations on the made by supplementary mechanism, in which blades are made to indent or crease the paper. Parallel creases may be made on the dotted lines i "i, to facilitate the bending outward of the V-shaped folds; but these are not so essential as the creases above referred to.
I do not claim broadly a paper bag composed of two strips united at the opposite edges, as this may be found in the application of L. O. Orowell, rejected November 20, 1867, in which case, however, the edges of the two strips are united by supplementary strips.
I claim as my invention- 1. Themode or process herein described of manufacturing paper bagsthat is to say, folding the opposite edges of two strips of paper inwardly, uniting the foldededges, and folding and pasting one end of the united strips, as set forth.
2. As a new manufacture, a paper bag composed of two strips of paper folded inwardly at their opposite edges, united by pasting the folds, and closed at one end, all in the man ner described.
In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
CHARLES T. PACKER'.
