MACHINE FOR MAKING PAPER BAGS.
Specification of Letters Patent.
Application filed February 25, 1910.
To all whom it may concern:
Be it known that I, Tnuouon HUGO, engineer, and a subject of the King of Prussia, vlerman Emperor, and a resident of Griinauerstrasse No. 27, Berlin, in the Kingdom of Prussia and German Empire, have invented certain new and useful Improvements in Machines for Making Paper Bags of which the following is a specification.
This invention relates to a machine for making quadrilateral paper bags the special feature of which is in the first place that several paper bags of the same or different sizes can be made at the same time, and in the second place that the machine can be adjusted for different sizes of bag in the simplest manner without having to dismount or exchange parts of the machine, this adjustment being effected simply by ad justing certain stops.
The paper bags are not made from a roll, but from sheets, that is to say, a large number of cut sheets of paper are stacked on a table and are fed from this successively to the machine. These blanks have the shape shown in Figure 1 of the accompanying drawings, the edge 12 being turned toward the machine. The bags are made by first folding the blank of the shape shown in Fig. 1 on the line 3 4 so that it takes the form shown in Fig. 2. The end flap 5 and the side flap 6 are then turned over and gummed down to make the finished bag shown in Fig. 3. On this bag there is therefore a side seam and a bottom seam. It will be seen from Figs. 2 and 3 that the bottom has a powder-tight seal at the corner, since the paper, owing to the form shown in Fig. 1, folds upon itself double and so forms at the corner a powder tight seal.
The machine for making the bag shown in Figs. 1, 2 and 3 is illustrated in longitudinal section in Fig. 4 and in plan in Fig. 5, Figs. 6, 7, 8, 9 and are detail views drawn to an enlarged scale and are eX- plained hereinafter.
The blanks of the shape shown in Fig. 1 are stacked on a vertically adjustable table 7 (Fig. 4), the sheets of paper lying with their edge 12 (Fig. 1) toward the machine. By means of a suction device 8 of known kind, the top blank from the pile resting on the table 7 is raised and then seized by the grippers 10 and drawn on to the folding table 11,. The edge 12 (Fig. 1) of the blank strikes against an adjust- .82 bent at a right angle.

able stop, not shown in the drawing but arranged on the folding table 11 in the plane A B, and is maintained in its proper position thereby. There then follows a downward movement of a blade 12, which is fixed to the lever 13 turning on the shaft 14. In this manner the blank on the folding table 11 is carried between the rollers 15 and 16 and is folded on the line 34 (Fig. 1). The folded blank, now having the shape shown in Fig. 2, is led from the rollers 15 and 16 to the rollers 17 and 18 between a pair of conveyer bands, of which the upper one 19 passes from the roller 16 over the tension roller 20 under tension rollers 21, 22 to roller 17 and returns under roller 23 to the roller 16. The lower conveyer band 24 passes from roller 15 under roller 16 and then, like band 19,'over tension roller 20, under tension rollers 21, 22, to roller 18, whence it passes under the tension roller 25, over the rollers 26, 27, under roller 28, over roller 29, and under roller back to roller 15. Several such conveyer bands are arranged in pairs on the rollers mentioned and at certain distances apart as shown in Fig. 5. Thus the folded blanks arriving between the rollers 15 and 16 are carried along by the pairs of conveyer bands over roller 20, under rollers 21, 22 between the rollers 17 and 18. There, as shown in Fig. 4, the blank is released for a short distance and arrives above the gum pot 32 and over roller 26 to the lower conveyer band 24 and by this is carried to the gumming device 31. The gum pot consists essentially in a trough Above the gumming device 31 is an adjustable stop (not shown) in the plane CD against which the edge 34 of the blank, carried along by the conveyer band 24 and already folded to the shape shown in Fig. 2, strikes; the folded sheet is thus retained in this position, with its flaps 5 and 6 (Fig. 2) above the trough 32. The gummer, consisting of a bar or the like shaped like the trough 32 and having been previously lowered until it dipped in the trough and then raised again, now descends to transfer gum from its lower edge to the flaps 5 and 6. The adjustable stop is then lowered so that the sheet can be carried on farther by the conveyer band 24 to the folding device 33. The latter is shown to an enlarged scale in Figs. 6, 7, 8, 9 and 10 and consists in a number of levers 35, 36 and 37 operating like tongs and arranged side by side. The upper levers 35 are connected together on the underside by a plate 35-, the lower levers 36 on their upper side by a plate 36 The lower levers 36 together with their connecting plate 36 are first raised until their front edge is flush with the folder 38. The folded blank (Fig. 2), the flaps 5 and 6 of which, as above stated, have been duly gummed, is delivered by the conveyer band 24L on to plate 36 and remains with its edge 3 t against an adjustable stop in the plane E F in which position the line 1-2 (Fig. 2) coincides with the front edge of the plate 36 In this position the upper levers 35 which, as already stated, are connected together on the underside by plate 35 press on the blank resting on the plate 36. In the closed position the levers and 36 move down- Ward around the shaft 39, whereby the flap 6 (Fig. 2) is bent as it passes against the edge of the folding flap 38. The movement of the levers 35, 36 continues until plate 36 is flush with the axis 38 of the pivot of the folder 38. This movement is shared by the lever 37; the levers 35 and their plate 35 then move upward, whereupon the folder 38 turns through an angle of 90 around the axis 38, completely folds over the previously bent flap 6, sticks it down, and then returns. By the upward motion of the levers and 37 the folded sheet on the plate 36" is not completely released, since it is still held by flat springs 43, 44 respectively carried by these levers. The lever 37 then moves downward alone. As soon as this lever rests on the plate 36 this plate with lever 36 and lever 37 moves downward so that the folded sheet is bent when passing edge a0 of folder 41, which is a duplicate of folder 38. After flap 5 has thus been upturned and after lever 37 has been raised off plate 36 folder 4:1 is rotated through 90 to fold flap 5 against the blank and paste it thereto. The bag is now finished and lever 36 with plate 36 descends as shown in the dotted lines in Fig. 7 for the purpose of allowing the finished bag to fall on to the receiving devices of any suitable known kind.
Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I clai1nis:
A machine for making paper bags comprising means for doubling a blank having a side flap and a bottom flap, means for providing said flaps with an adhesive, means for conveying the doubled blank to aclamp ing device consisting of a plurality of substantially horizontal clamping levers, means for opening and closing said levers, a pivoted quadrantal side flap folder in front of the clamping device, a .quadrantal bottom flap folder laterally flanking said device, means for intermittently lowering the clamping device, and means for successively imparting a partial rotation to the folders, thereby consecutix ely folding the side flap and the bottom flap against the blank.
In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
THEODOR HUGO. Witnesses VOLDEMAR HAUPT, HENRY HASPER.
