. My invention relates to an improved method of making bags and more particularly to duplex bags in which a novel construction of the inner ply or liner blank and outer ply r cover blank-form important parts of the finished ba Reference is made to m copending apphcation, Serial No. 199,540 ed. June lily invention is especially adapted for use in the manufacture of duplex or lined bags, usually employed for packing and shipping merchandise, such, for instance, as smoking and chewing tobacco, it being necessary that packages containing this class of goods be 1 made, not only from air and moisture-proof 'material. but also after the bag has been filled with tobacco and closed, it has recently been desired to entirely surround or cover said filled .bag with an additional cover of a thin wax paper or a paper of similar moisture-proof construction. In order to efliciently apply and seal said additional cover of thin moisture-proof paper upon the filled *and closed bag by the tobacco manufactures packing equi ment, it is essential that the bag be of per ect form and that the ears at the bottom of the bag be of limber or flexible construction, whereas heretofore the flexibility of said ears was not all important' factor, nor was the trueness in shape of the bag so particular. However, the flexibility of said ears and the correctness of shape of said bag are very essential features when it is desired to put said additional moisture proof cover upon said filled and closed bag by the manufacturers present packing equipment.
The primary object of the present invention is to provide an improved inner ply or liner blank, an improved outer ply or cover blank,and an improved method of making same, which entirely eliminates the objections and difliculties above referred to, and the practice of which improved method re-' sults in a better made or squarer shaped bag with a minimumnumber of cast-ofls, due to the required exactness of the bags for applying said additional cover of thin moisture-proof paper by the. tobacco manufacw turer s packing equipment.
1927. Serial no. 207,675.
Further objects of my invention are to provide a multiplex bag, as above described and for the purposes intended, which is simple, eflicient, inexpensive to manufacture, and the 1 construction of which is highly desirable for use upon packing equipment where an additionalcover of tllllllllOlStllIG-PI'OOf paper is applied to the bag after the latter has been filled, closed and sealed by said packing equipment. 6
Briefly and generally stated, the invention consists in cutting away a portion of the inner ply or liner blank (adjacent the portion of-the cover blank forming the ears of the bag, previous to being superposed upon saidcover blank and adhesively secured thereto) and cutting away a portion of the outer ply or cover blank at an angle to the central transverse fold, so that the excess quantity of paper heretofore folded within the cars (thereby making them stiff and nonflexible) is eliminated, thus making them limher or flexible and easily handled by the manufacturers packing equipment.
My invention further consists in the construction, combination, location and arrangement of parts and in the bag as an article of manufacture, as herein set forth and claimed.
In the drawings:
Fig. 1 represents a longitudinal strip or web of paper, the longitudinal edges of which have a portion cut away at spaced intervals, as shown;
Fig. 2 represents two longitudinal superposed strips or webs of paper of diflerent 35 widths pasted together at intervals a short distance from their longitudinal edges and at certain points or spots in the center thereof, the liner or upper web of paper being cut away at its longitudinal edges atspaced in- I tervals, as shown in Fig. 1, previous to being superposed upon the narrower web orcover 7 ply of paper;
Fig. 3 is a similar view to Fig. 2, showing by dot and dash lines the parts cut away in forming the individual bag blanks and showing one of the bag blanks detached and discarded or waste parts cut away; i
Fig. 4 is a plan view of the bag blank for a single bag clearly showing the cut-out pcr- 9 Fig. 9 is a side elevational view of a bag" formed according to the blank shown in Fig. 4, part of which is broken away and shown by vertical section and the ears of which are shown before being bent in close proximity with the bottom of the bag;
Fig. 10 is a similar view showing the ears folded against the bottom of the bag;
Fig. 11 is'an edge view of the bag shown in Fig. 9;
Fig. 12 is an enlarged vertical section taken through one of the ears of the bag on a plane corresponding to line 12.-12 of Fig. 11, the folded position of the car being shown by dotted lines;
Fig. 13 is an enlarged vertical section taken on a plane corresponding to line 13-13 of Fig. 11, looking in the direction of the arrows; and
Fig. 14: is an enlarged vertical section similar to Fig. 13 but of the old construction, showing the multiplicity of plies of paper within the ears.
The method of making the bag is substantially as 'follows A plurality of webs or plies of paper 1 and 2 respectively, are drawn in registry with each other from rolls by any suitable means. The web 1 however, is provided with cut-away portions 1 previous to being superposed upon the ply of paper 2*. Narrow layers of glue or paste 3 are applied near the respective longitudinal edges between the adjacent webs or. plies of paper 1 and 2 on side 4 of the bag blank 5. Said layers of glue preferably extend from end 6 to scored line 7. It has been found in practice, however, that by omitting a small portion of the glue stream at 8 over the score line .9, the top closure portion of the bag is more readily handled by the manufacturers packing equipment. The plies of paper are then pressed together upon said layers of paste whereby they are permanently attached together in accurate registry with each other, asshown in Fig. 2.
The important step of the operation consists in dieing out or cutting off the longitu- A dinal strips 20 from side 41, which strips are shown detached in Fig. 3. The edges of side 10 are then folded inwardly to form inturned securing flaps 11. v
A coat or layer of glue aste 11" is'then applied to the exposed sur ace of each outer flap 11, as shown in Fig. 3. The individual bag blank 5 is then severed or out 01f from the webs of paper 1 and 2 respectively. The sides 4 and 10 of said bag blank are then folded transversely on central score line 12 and the longitudinal edges of side 4 of the bag are then pressed down upon the glued faces 11" of flaps 11 whereby the bag is completed and issued from the bag machine in a" To prevent the liner 1 from bulging or separating from thecover 2 at the top of the bag when the bag is opened by the manufacturers packing equipment previous to filling with tobacco, I apply a spot or drop of glue 13 between said cover and liner, as clearly shown in Figs. 2, 3 and 4, respectively. The inside ply or liner is permanently fastened to the outer ply or cover by this method of construction .to prevent shifting .or withdrawal thereof, which is a decided advantage, particularly on account of the easy and simple manner in which it is mechanically accomplished. The plies of paper 1 and 2 being glued together in registry with each other, after ply 1 has been cut away at 1", as shown in Fig. 1, said plies are held in absolute and accurate registry with each other during the subsequent operations, thereby preventing any shifting of the plies relative to each other, as is the case where the plies are glued together after the dieing out operation. Two or more complete rolls of paper can be glued together, as shown in Fig. 2, on a separate machine before making it up into bags, ready for printing, and this can be done on a very simple combining and rewinding machine. In other words, the plies of paper can be unwound from separate rolls and after dieing out the portion at 1 of the liner, the plies of paper may be glued together at the necessary points and then rewound upon a single roll for manufacture into bags on simple bag making machinery, such as is used for making bags of single ply material. In doing this, all that is required is to mark or cut into the paper an identifying mark to show the'regist-ry point for the dieing out knives of the bag making machine. In this way, if desired, the cutting away of ply 1 and the gluing together of plies 1 and 2, as shown in Fig. 2, could be done by one organization or factory and the dieing out and completing of the bag, as shown in Fig. 3, could be done by another organization or factory, so that if the sheets or plies of paper are glued together the material can be handled as if it were a single piece of paper, instead of a plurality of sheets of paper, This is a decided advantage in the construction of the bag since it enables the bag to be constructed more readily and economically by the use of simple, instead of complicated, machinery. The inturned flaps of the inner and outer ears of the bag when formed ready for re-' ceiving its contents. A bag blank formed in this manner permits an additional covering of moisture-proof paper to be easily applied or put on after the bag has been formed, filled and closed by the manufacturers packing machinery.
WhileI have set forth a particular construction and method, it will be understood that this is merely by way of illustration and the invention is capable of modification without material departure from its scope or spirit as, defined in the claims, as for instance, as shown in Figs. 7 and 8, respectively, the inner ply or liner 1 may be cut,
" as shown at 1 or 1, which will also aid in producing abag of the character described so that the ears of said bag will not be held in open position by their stifiness but will readily assume a position in close proximity with the bottom of the bag when said I bag is in the open position ready for receiving its contents.
What I claim as new by Letters Patent is:
'1. A multiplex bag having outwardly extending ears and comprising a cover and liner, the liner being entirely removed or cut out in that portlon of the bag which forms the ears to permit said ears to be perfectly and compactly folded against the bottom of the bag.
2. A multiplex bag having outwardly extending ears and comprising a cover and liner, the liner being entirely removed or cut out only in that portion of the bag which is folded to form the cars so that'said ears and desire to secure may be easily and compactly folded against the bottom of the bag.
