4 Claims.
This invention relates to carry bags. particularly concerned with paper carry bags of the type usually given away by retail merchants to their customers and which are therefore preferably produced as inexpensively as is consistent with providing a strong bag equipped with adequate carrying handles.
An object of the invention is to provide a method for making such bags which reduces manufacturing costs to a minimum while resulting in the production of a satisfactory carry bag. Other objects may be inferred from the following disclosure of what is now considered the best form of the invention.
The accompanying drawings show in Fig. 1 the progress of a paper -bag web as it is processed into bag tube lengths in accordance with the invention and in Fig. 2 a perspective of nished bag resulting after closing of the bottom of one of the bag tube lengths.
More specifically the paper bag web I is suiciently heavy p-aper for the purposes demanded of a carry bag of the conventional size range and it is wide enough to permit it being folded longitudinally along two fold lines so that its opposite edges can overlap sufficiently to provide an adequately strong seam when the overlapped portions are adhesively secured together.
The first step is to form transverse lines of weakness in this web I at bag length intervals, transverse lines of perforations 2 being shown. The bag length intervals should be just enough longer than the ultimate bag length-to provide for folding up and adhesively securing a portion of each bag tube length bottom as required to make a bag bottom closure for each bag.
The next step is to apply spots of active adhesive 3 to the surface `of the web I that Will be the bag inside with these spots 3 applied en' Next paper patches 4 are applied to the spots of active adhesive 3. These patches 4 are long enough to span the lines 2 in each instance and to project substantial patch portions across these lines longitudinally of the web to the opposite sides which are free from the adhesive spots It is 3. The patches 4 are shown as being rectangular in shape and they should be adequately long and wide to permit secure xing to the web with the projecting free or unattached portions providing room for the formation of handle openings.u These patches 4 are made of paper of substantially heavier weight than the paper of the web I. The adhesive spots 3 are contoured to cause substantially the entire areas of the patches 4 to adhere to the web I on the one side of ther lines 2 in each instance. If the ordinary wet paste is .used the patches are applied prior to drying of the paste and while it is therefore still active.
The web I is next tubed to form a bag tube.
This is done by. folding the web longitudinally on one fold line 5 which is located so that one of the web edge portions is offset from the other, and then folding this offset edge portion along a fold line 6 so it overlaps the opposite edge portion. Conventional tubing methods maybe resorted to including the usual edge pasting and seam pressing to provide a suitable bag seam on the back wall of the ultimate bag. This operation is not illustrated in detail since bag tubing is well known to those skilled in the art. A bag tube I results from the foregoing that looks like a conventional bag tube With transverse lines of perforations at the bag length intervals. However, the inside of this bag tube, of coursecontains the patches now aligned and superimposed in registration with each other and -with the portions beneath the lines of perforations firmly secured to the tube insides `but with their portions projecting above-their lines of perforations free from the tube insides.
Now by tensioning this bag tube at the transverse lines of perforations bag tube lengths 8 are created, each equipped with a pair of projecting patch portions flrmlysecured to itsinside. Therefore, after the ordinary step of closing each bag tube length bottom by folding up a portion thereof and pasting it against the portion of the bag outside it overlaps, suitable die cutting of the projecting portions of the patches 4 to provide for example, displaceable tongues 9. a nished bag is produced. The tongues 9 may be formed by simultaneously severing the superimposed patch portions so that a single die cut does the job. Any type of handle opening may be formed as exemplified by merely forming transversely elongated handle holes. Preferably the tongues 9 are formed, by appropriate severance,
4because this permits these tongues to be swung simultaneously in a single direction so as to 3 interlock the tube handles together, close the bag tight and provide a rounded surface for grasping by the hand.
Although the method has been described as though carried out by hand operations, the method is adapted for use in connection with machine production methods. The spots 3 may be applied; by suitable spotting equipment as the web l lea-ves the usual large supply roll with the lines of perforation formed either shortly before or after this spotting. Preferably the perfora-r` tions are formed prior to spottinglto avoid the danger of the adhesive contaminating the perioratcr. The patches 4 mayV be. applied autor. matically from two separaterollsoi` paper strip of adequate weight. Then when the web goesl over the former and through the ',seamer andlon. to the tube tensioner or snap oi and finally through the bottom closer, the machine.L delivers bags that are completely finished excepting for the diecutting of the handlesautomatically provided by the practiceof theinventon.` Die cutting equipment may be applied to the end ofY the bag machine so thatzthemachinedelivers completely. finished bags.
In connection with the application of the patches, a machine particularly adapted for this purpose is disclosed and claimed by-an application led by George W. Poppe, bearing Serial No. 747,264, and having a ling date of May l0, 1947 (now abandoned). A bag making machine particularly adapted for tension severing the bag tube into bag tubev lengths is disclosed and claimed by Patent No. 2,466,823, which issued April 12, i949, on an application iiled by George W. Poppe, bearing SerialNo. 702,627, and having a filing date of October ll, 1946;
In connection with machine operations, placement of the patches 4 rerrn'itelyy from the edges of the web l and fromftlietube-folding lines 5 and 6 lavoids interference kb'y-tl'iese patches, with the tubing step. Thus-they are free, from the fold and bag seam forming." element.
The methodY disclosed herein produces paper carry bagsf with what is believedV the ultimate in economy. This naturally permits the selling price of the carry bags somade to bev lowered to a degree making carry.` bags, available to; the public underv many circumstances where` the public has heretoforebeen deniedzthe. convenience of these bags due to the-.economics involved.
- It is important to note thatthis desirable object is attained by using patches thataresimply fiat strips of material and which are, cachan` integral part throughout. used asy attachments for other handle parts; but themselves are` long enough for attachingV to the bag walls and to project above thebag wall tops to by themselves form. the handle portion. One
The patchesV arel not 4 die cut forms the handle opening. The resulting handles project upwardly from the bag insides and permit flat stacking of a number of the bags while providing a pair of handles each having the same sized ringer opening, as contrasted to one being smaller than the other. Hence the described tongue arrangement is possible and the gser is provided greater comfort in carrying the Although the invention has been exemplied as applied to a plain bag, it might also be used with other typesgoi` bags. For example, when greater size is desired a satchel bottom could be used. Qtherr` variations; may.v prove desirable.
