Nov. 25, 1930. T. M. ROYAL 1,782 884 METHOD OF MAKING PAPER BAGS Filed Feb 7. 1929 Patented Nov. 25, 1930 THOMAS M. ROYAL, OF PHILADELPHIA, PENNSYLVANIA METHOD OF MAKING PAPER BAGS Application filed February 7, 1929. Serial No. 338,075.
My invention relates to the art or method of making paper bags, particularly bags of the character in which either the inside or the outside or both the inside and outside are provided with a coating of one substance or another, as may be selected. Wax may be men- 'tioned as one substance which is quite generally employed as a coating for one-surface or the other of bagsto render them moisture proof and also impervious to grease. The latter is desirable if the bags are. employed for holding greasy objects; for example, po-
I tato chips. The invention is not dependent upon the substance of the coating, because such substances may vary at' the election of the manufacturer and also may be varied to meetconditions as they may arise neither is the invention limited to the uses for which the bags may be employed after they have been manufactured. Wax, paraflin, and other like substances may be employed to form the coatings.
The general object of the present invention is to provide a novel and improved method in the manufacture of bags whereby in the process of manufacturing the same one side or the other, or both sides, if the manufacturer should so elect, is or are provided with a coating of a suitable substance, such as wax. I
It also is an object of the invention to pro vide a novel method in the manufacture of bags of paper or other suitable flexible material wherein wax or other suitable substance is applied as a coating at intervals to portions of either one or both sides of'a web of paper, the coating being omitted from other parts of the said Web in adjoining 4Q lateral relation to one edge of each of the portions or sections of coating which may he applied.
\Vithout further stating the objectsof the -cia11y in accordance with the art or meth invention it maybe set forth that the invention comprehends broadly a method wherein and whereby coatings of a suitable substance, such as wax, are applied at intervals to a web of paper in suchmanner as not to interfere with the uniting of the edges of the web of paper and of other portions thereof in the formation of the bag structure.
By reference to the drawing which accompanics this specification and forms a part thereof the invention and the underlying principle thereof will be readily understood as the description proceeds.
Inthe drawing,
Fig. 1 is a plan view of a fragmentary por-. tion of a web of paper on the exposed sur- 0 face of which sections of a coating of wax or the like are shown at spaced intervals;
Fig. 2 is a similar view in which in addition to the portions of coating a strip of adhesive is shown along the margin of one side of the Web or sheet, which margin is free from coatings of wax;
Fig. 3 is a viewin perspective of a fragmentary portion of a tubular section showing the manner in which the opposite side portions of the Web are fplded over, with their marginal edge portions in overlapped relation and indicating the manner in which the said marginal edge portions are secured together;
Fig. 4 is a View in perspective of a section of a tubular portion like that indicated in Fig. 3, the said section being formed by severing the tubular structure in the intervals between adjoiningcoated portions, and the said view also showing a strip of adhesive along one end portion thereof;
Fig. 5 is a view in perspective of a bag formed by folding over one end portion of the tubular section shown in Fig. 4; and
Fig. 6 is a View in perspective of a fragmentary portion of a tubular structure indicating a coating of a suitable waterproofing substance at spaced intervals upon both the inner and outer sides of the said tubular 90 structure.
In the manufacture of paper bags commerod of my invention, machines known in the art as paper bag machines or bag-forming machines will be employed, but as the art or method may be carried out manually I have elected not to encumber the disclosure by the showing of a machine which, no matter how sketchily or diagrammatically it may we be illustrated, would lend more or less of complication to the description of the invention. On the contrary, I have chosen to illustrate the invention in the simplest possible way by reference only to the web or sheet of paper or other material and the areas thereof to which the coating of wax or other equivalent substance is applied and the relation of those areas to each other and the smaller areas from which the coating is omitted.
In the drawing I have shown a fragmentary portion of a web of paper 1 to portions of one surface of which, as illustrated in Figs. 1 to 4 of the drawing, a coating 2 of a suitable material, such as wax, is applied. The coatings are applied to the web 1 at spaced intervals, as shown. The spaces 3 between the successive and adjoining sections of coating are of such width as may be necessary to permit severing of the web, after its formation into a tubular structure, in the manner common to the manufacture of paper bags without cutting into the coated areas. It will be noted that the areaiof each of the sections of coating 2 is of less width than the width of the web 1, so that a marginal edge portion 4 of one side of the web is free from the coating. A narrow strip of adhesive 5 is applied continuously along the uncoated marginal edge portion 4 of the Web in parallel relation to the adjoining edges of the sections of coating 2. The relation of the sections of coating 2 to the strip of adhesive 5 is clearly illustrated in Figs. 2 and 3 of the drawing.
The sections of coating having been applied at intervals, as illustrated in Figs. 1 and 2, and the strip of adhesive 5 also having been applied to the marginal edge portion 4, as illustrated in Fig. 2, the opposite side portions 6 and 7 of the web are then folded inwardly toward each other as illustrated in Fig. 3, with the marginal edge portion 4 placed in overlying relation to the 11pper side of the marginal edge portion of the inwardly folded side portion 6. It will be seen that when placed in the relationship as illustrated the adhesive is interposed between surfaces of the marginal edge portions of the web to which the sections of coating 2 have not been applied. Hence the adhesive is effective for securing the overlapping portions together.
A tubular structure having been formed in the manner as described and as illustrated in Fig. 3, the tubular structure is then severed at intervals corresponding to the intervals of the uncoated spaces 3.
In Fig. 4 a severed sectional portion of the tubular structure shown in Fig. 3 is illustrated and it will be noted that at one end of the said section the uncoated portion 8 of one side thereof projects beyond the edge 9 of the opposite side which comprises the inwardly bent opposite side portions 6 and 7 of the web. At the opposite end of the said tubular section the end of the side which comprises the inwardly turned overlapping side portions 6 and 7 is extended, as indicated at 10, beyond the edge indicated at 11 of the opposite side. In other words, the ends of the opposite sides of the tubular section at the opposite ends of the said section are reversely arranged or related.
.The tubular section, as illustrated in Fig. 4, having been formed, a narrow strip of adhesive 12 is applied along the uncoated inner surface of the projecting end portion 8, which strip of adhesive is extended at its opposite ends over the adjoining end portions of the inwardly turned side portions 6 and 7 as indicated at 13. The adhesive having thus been applied, the end portion of the section is then bent over into position, as indicated at 14 in Fig. 5 of the drawing, and is retained in such position by the holding and binding effect of the portions of adhesive 12 and 13 previously referred to.
In Fig. 6 of the drawing I have illustrated a section of a tubular structure identical with that shown in Fig. 3 except that portions of the outer surface as well as the inner surface are provided with sections of coating 16 at intervals. The sections of coating 16 upon the outer side are located in opposed relation to the sections of coating 2 upon the inner side of the tubular structure; but, as will be noted, the uncoated marginal edge portion 17 of the outer side of the structure is located at the opposite edge portion of the web from that of the uncoated marginal edge portion 4 of the inner surface.
In commercial practice, as has been indicated already herein, the method of my invention would be carried out by means of suitable machinery, but as will be obvious, the method is capable of practice without the employment of machinery and hence it has been so described.
As I have previously indicated herein, webs or sheets of any suitable flexible material may be employed. Hence by the word paper employed in the specification and claims I intend to include not only paper but any other flexible sheet material which may be adapted to and suitable for the purpose of making bags.
Although I have illustrated the invention as applied to a bag in which the opposite edges thereof consist of a single fold and in which one end thereof is folded over on to an adjoining portion of the bag structure to close the same, it will be understood that the invention is not limited to bags of the specific construction shown but may be employed in the manufacture of bags of any other of the known types of structure. For example, the invention may be employed in the manufacture of bags wherein the opposite edges thereof consist of two or more pleats or folds and also may be employed in tions at the opposite ends of the the manufacture of bags in which the bottom and top ends thereof are or may be closed in an altogether different manner from What is illustrated in the drawing.
