METHOD OF MAKING BAGS Filed Sept. 6, 1953 dN V EN TfJR.

ATTORNEYS. I,

Patented Sept. 22, 1936 UNITED STATES 2,054,892 METHOD or MAKING sacs Adolph Potdevln, Garden City, N. Y., assignor to Potdevin Machine Company, BrooklynrN. Y., a corporation of'New York Application September s, 1933, Serial No. 988,279

3 Claims. (Cl. 93-35) This invention relates to a method of and.

. apparatus for making bags and to the bag itself as an article of manufacture and is directed to.

a method and apparatus particularly well adapted for making bags of cellophane, glassine and like materials, as distinguished from paper.

In the accompanying drawing:

Fig. 1 is a plan view somewhat diagrammatic of an apparatus constituting one embodiment of my invention;

Fig. 2 is a side elevation of the apparatus of Fig.1;and

Figs. 3, 4, and 5 show the bag in the various stages of its manufacture.

Referring to the drawing in detail: The material is taken from a supply roll I and the web, designated 2, is led about a roller 9 and past plates 4 which are adapted to fold the opposed edges of the web over toward each other upon' the main body of the web toform flanges 5 at opposite sides of the web. 1 p

The web then passes between rollers 6 by which the flanges are turnedoutwardly again so that the web is once more flat.

In its flattened condition the gweb passes notching mechanism comprising notchers l and 8 at each side of the web and adapted to notch the web as shown at 9 and I9. The notchers i and 8 are mounted on the same shafts. so The notchers I and 9 are held to their sup portingshaft II by screws l2, so that the spacing of the notches 9 and I9 lengthwise of the web 2 may be varied to suit difierent conditions.

The web still in opened-up or flat condition then passes about rollers l3 and II to bring the flanges 5 of the web into contact with adhesiveapplying discs I5. I

These adhesive-applying discs as seen from Fig. 2 are segmental so that alternate flanges 5 have the adhesive stripes l6 applied thereto. In other words, the flanges to one side of one pair of opposed notches 9 will have adhesive applied thereto, while the adjacent flanges at the other side of these notches will be left plain. The discs ii are made adjustable as shown at I! to vary the length'of their periphery.

The web next passes plates l8 which are adapted to turn the flanges 5 which have had adhesive applied thereto inwardly again, so that these flanges will be pasted down to the'body of the web 2. I

To insure that. only alternate flanges will be turned inwardly again, I provide rocking fingers l9 intermediate the roller l4 and plates 19, these fingers which engage the web along the line of the fold which provides the flanges 5 being so timed that the leading end of a pair of pasted flanges will be directed above'the end of the plates l8, while the leading end of the succeeding pair of flanges will be directed below these 5 plates.

The web next passes between rollers 20, past cutting off mechanism 2i and between rollers 22 and 23. e

The cutting ofi mechanism comprisesa rotary l0 cutter bar 29 driven in the direction of the arrow on Fig. 1 cooperating with a fixed member 25. The function of this cutting off mechanism is to sever the main body of the web transversely, across opposed" notches l0 but an appreciable 15 distance to one side (to the right as viewed in Fig.1) of the center of these notches so as to leave a relatively long flap designated 26 in Fig. 1 on the trailing edge of the cut elf portion and a relatively short flap 21 at the leading edge of 20 the adjacent section of material.

' Each length of material, therefore, approximately double the length ,of the finished bag and as shown in Fig. 1 is composed of what I shall term two panels designated 28 and 29, respec- 25 tively, the flanges 5 of the panel 28 being turned inwardly over upon the body of the web 2 to which they are pasted, while the flanges 5 on the panel are in an opened up condition.

The length of material shown at the left in 90 Fig. 1 passes from' the rollers 23 to forwarding and creasing rollers 90 and 3ll The roller 39 is provided with a creaser blade 92 and the roller 9! with a gripper 93 controlled by a cam 94. The

. setting and timing of these two rol1ers 90 and 95 9! are such that the creaser blade 92 engages the web substantially along the line 95 of Fig.4

' to force the web downwardly with respect to, the

The folded material then passes between roll- 5 ers 98 and finally between a pair of superposed bolts 99 which fold the flanges 5' of panel 29 over upon the panel 28 as shown in Fig. 5 which completes the has.

The finished bag, it will be observed, is made from a single piece of material, its edges being very strongly reinforced'by the manner in which the flanges 5 are handled, thus adapting my method for making bags from materials such as cellophane, glassine and like materials which are easily torn.

What I claim is: 4

1. The method of making bags which comprises folding the edges of the portion of a bag length which eventuallyis to constitute one wall of the bag over in superimposed relation to said portion along a longitudinal line adjacent each edge of said portion of the bag length, and pasting the folded over edges to said portion, then folding the bag length along a transverse line which is said wall and securing the turned over edges to said outer face.

2. The method of making bags which comprises notching the opposed side edges of a traveling web at predetermined intervals, severing the web transversely into bag lengths at alternate notches to provide a bag length with a pair of opposed notches intermediate its ends, folding over the side edges of that part of the bag length which ,is to one side of said intermediate notches along said face.

a longitudinal line adjacent each edge of said portion of the bag length and pasting the foldedover edges to said portion, then folding the bag length along a transverse line which intersects said intermediate notches, and folding the side edges of the remainder of the bag length along a longitudinal line adjacent each edge thereof over upon-the outer face of the bag thus formed and edges of that part of the bag length which is to one side of said intermediate notches along 'a longitudinal line adjacent each edge of said portion of the bag length, pasting the folded-over edges to said portion, then folding the bag length along a transverse line which intersects said intermediatenotche's and folding the edges of the remainder of the bag length along a longitudinal line adjacent each edge thereof and over upon the outer face of the bag thus formed and securing the last-mentioned folded-over edges'to ADOLPH POTDEVIN. so
