POUCH MAKING MACHINE Fi1ed' March'4, 194s 4Shee'ts-Sheet4 VINVENTOR.
Patented Oct. 10, 1950 Harry. W. Ligon, Atlanta, Ga., assignor to Atlanta 7 Paper Company, Atlanta, -Ga., 7 a corporation of Georgia Application March 4, 1946, Serial No. 651,911
The invention relates to machines for making pouches'as of, paper and has as an object the provision of a'ma'chine for making a variety of sizes of pouches by automatic action.
A further object of the invention is the provision of amachine for sealing together two strips of paper at three sides offrectanglesiand at least partiallyseveringthe said rectangles to provide pouches open at one edge and sealed at the three remaining edges.
It is a further object of the invention to provide a novel sealing means for the purpose re- Ierred to.
It is a further object to provide novel feeding means which will advance the material to the sealing and cutting means without placing strain upon the portion of the material under treatment.
Further objects will appear from the following description when read in connection with the accompanying drawings showing illustrative embodiments of the invention and wherein:
Figure l is a plan view of a machine of the invention;
Fig. 2 is a vertical section on line 22 of Figure 1;
Fig. 3 is a plan view of a strip of pouches with one wall of certain of the pouches broken away;
Fig. 4 is a detail transverse section of the heat plate for sealing the pouches;
Fig. 5 is a bottom plan view of the structure of Fig. 4;
Figs. 6 and '7 are plan views of presser plates carrying the cutting knives; and
Fig. 8 is a perspective view of a portion of a knife.
As shown, the device comprises a frame I!) having a drive pulley ll belted by a belt l2 to a source of power not shown. The pulley H fast on the shaft l3 drives gear M in mesh with a gear keyed to a cam shaft [6. Upon the cam Shaft is a main cam ll engaging roller I8 actuating link [9 and supported by arms pivoted at 2| to the frame. The link I9 actuates toggle arms 22, 23 to cause reciprocation of block 24 carrying the presser plate and knives to be described. Upon shaft IE is also shown a cam 25 actuating an arm 26 to cause reciprocation of the feed blocks 27, 28 which are linked together by links 29, 3d. The material from which the pouches are to be formed is shown as supplied in rolls 3|, 32 and webs from the respective rolls are led in superposed relation into the machine, the inner surface at least of the webs being of such a character that when heated and pressed together they will adhere.
1 Claim. (01. 93-45) -Heating for the purpose is shown as provided by. a stationary heating head 33 which may be provided to receive steam or may be heated by electrical means, not shown. The heat transmitting plate 34 at the bottom of the head is shown as provided with metal bars 35 to contactthe material only at the portions which it is desired shall be caused to adhere The surface of ,the plate 34 between thebars 35 is shown as heat insulatedby material 36 such as asbestos'secured to the plate as by means of screws 3'1. The bars 35 may be removed and other bars differently spaced may be placed upon the heating head, screw holes 35 being provided for the purpose, to produce pouches of different sizes, the heat insulating material being correspondingly adjusted.
To press the pouch material against the heating bars 35 there are shown bars of compressible material 38 as of rubber carried by the reciprocating plate 24.
The assembly of the bars 33 and interspersed blocks 38 with a carrying plate is shown as locked into a form by means of quoin wedges 39 and the assembly of the bars with a supporting structure may be made up of units locked up in a chase by the quoins in a manner common in the printing art, whereby the manufacture of different sized pouches may be provided for with corresponding arrangements of the heat bars 35.
To cut the pouches apart along the center of the adhering localities there are shown knife bars 40 held between the compressible strips 38 and so arranged as to be flush or slightly below the surface of the compressible strips when the latter are not under pressure.
To leave the strips of pouches in assembled condition to assist in feeding the material to and away from the pressing elements, there are shown notches M in the cutting bars at which .locations the pouches are not severed and are left in a strip from which individual pouches can be readily removed by tearing the uncut portions apart.
The cam I I is shown as formedwith an extended raised portion 62 to provide a dwell of the pressure against the pouch material of a predetermined interval of time, taking the speed of the machine into account, in order to give the adhesion required.
To return the arm 2|] from pressing position there is shown a spring 43 anchored to the arm and to the frame at M. The arm 26 between feed movements caused by cam 25 is returned in operation for a new stroke by means of a counterweight 4 5 and a flexible strip or cord 66 passto the left in Fig. 2 they will feed the material a distance required to make a set of pouches.
In Fig. 3 the pouches are shown as united at adhered strips 52 and cut apart through thecenters of the strips as at 53, 54 except at the small locations 55 corresponding to the notches M in the cutter bars. I
The operation of the device will be clear from the above description.
Minor changes may be made in the physical embodiments of the invention within the scope of the appended claim without departing from the spirit of the invention.
I claim:
In a pouch making machine, in combination: a plurality of strips associated to form the geometrical outlines of a plurality of pouches; means to heat said strips; means to press a sheet, comprising a plurality of layers of material adherent when heated and each in theform of a continuous web, against said strips; means to at least partially sever the sheet along the center line of the adhered portions in the act of sealing the same; and means to intermittently feed said sheet between said heated strips and said pressing and severing means, comprising a rod extending over the web at the intake side of the pressing means and a second rod at the discharge side thereof; a plurality of dogs pivoted about said rods and spring pressed for pressure against the web; said dogs inclined in the direction of' feed; means linkin said rods together; and means to move said feed means synchronously in alternation with press movements.
