BAG-MACHINE Specification of Letters lPatent.

Patented Feb. 9, 1909.

application filed June 16, 1906. Serial No. 322,072.

To all whom it may concern:

, Be it known that 1, JOHN FREEMAN Arms,-

. a citizen of the" United States, residing at "the fol of the present application.

Portland, in the county of Multnomah and State of Oregon, have invented new and useful Im rovements in Bag-Machines, .of which lbwing is a specification.

' My invention relates to bag machinery and especially to machines in which a continuous length or web of cloth is passed through a printing press to have a suitable brand imprinted on it at suitable. intervals, thence severed into folded.

My object is to group in a single organism the several printing,v cutting and folding mechanisms; and particularly to render these mechanisms mutually adjustable, in every respect to the manufacture in a practical and commercially-successful manner, of bags of different sizes.

The present invention pertains more specifically to the means for operating and conmeans for adjusting the folding device to the rest of the machine; it also covers other matter, but thesearethe two mam features Having reference to the accompanying drawings,.-

r Figure 1 is a side elevation of the principal parts of the stock roll, printing press and cutter-feed mechanism. l-ig. 2 is a similar view. in continuation of l=-ig. 1: the two views taken together representing a side elevation of the present invention. Figs. 3-4 correspond respectively to igs. 12 and representdiagrammatically the driving connections and carrying'tapes and the web in its course through the. machine. Like l igs; 12, the li-igs. 3'4 should be viewed together. Fig 5 is a partialplevation and partial diagrammatic representation of the oldingmechanism; the full-line position ofthe carriage indicating its position for small bags'and its dotted-line position that for large bags; ig; 6 is, a detail of the spring guide for the free end of the knife and of the resser roller. Fig. 7 is a detail of the means or operating the folding blade. Pig 8 is a plan ofthe cutter andfolder omitting certain parts" of .the machine. l

' A re resents the roll of stock which is to be prints at regular intervals and out into W proper bag lengths and the bag sections final y venience of illustration in Figs. 3-4 thestock in its travel through the press and machine is represented in heavy lines by D; the sprocket chains and driving connections bysingle lines, and thcconveying tapes and belts by broken lines. From roll A (Fig. 3) which is mounted to turn free, the fabric is carried between the rollers 2 driven in unison with the rest of the machine. Thence it passes between the form or type cylinder 3 of the press and the im ression cylinder 4 being fed intermittently tlliereto by means of the feed roller 5 resting normally on the impression cylinder. 6 is another roller on the other side of cylinder 4 which is movable with roller 5 and operated by the same means. These rollers are operated through the agency of an eXpansible and adjustable cam 7, Fig. 1 on the shaft of the constantly revolving form cylinder. The cam 7 is com posed of a plurality of concentric sectors adapted to be opened out or closed up to pression cylinden. The roller 6 serves also to strip the cloth from the form to prevent 1 the cloth following around'with the cylinder. I after making the impression. Thus it is seen that when the cam? contacts with the roller on arm 9, the shaft 11 is rocked to' lift both rollers 56, from the-impression cylind'er. When the cam leaves the roller 81a spring 14' operates to pull'a'rm 9 back and a low the re p'ression cylinder-to feed the cloth forward. ihe'peri'od of contact of the rollers 56with the imression cylinder regulates the amount I inder inde as suitable lengths, the Width of the rolled stock with the 'c.

of fee at each revolution' of the formcylendent ofthe contact of the form oth and impression cylinder anders 56 to contact with the imthe amount of feed .of cloth depends on the .:-as-1night occur if the feed' of thewcloth depended on the. contact of the form and impression cylinders alone. The adjustabilityat the cam sectors allows a wide range of 'frariation in the time and amount of feed to the ress. For large bags thesectors would be vc osed mor'e than for. small bags. The gtwo cylinders are driven positively in unison idndgat the same surface speed by reason of the inter-engagement of the gears 15.16 on the respective cylinders.

18 represents the, inking rolls which are preferably mounted on ad ustable carriages "and each adapted to apply a different colored ink to adifferent area of the brand.

Leaving'the rose, the printed length offabric is .prefera 1y, su ported on an inclined plane or table 19 whic is carried by and adjustable with the ress as will be more fully e' 'lained later.

an adjustable tension rod 21 whose functions --be made apparent hereinafter. Thence the cloth passes to the feed rolls 22-.23 by which it is fed intermittently to the knife or cutter 24; first coming after leaving rolls 22%23, upon the constantly running ta cs 25 and assing beneath the adjusta le resser r0 er 26, which latter holds the fabric at, evens out the creases and keeps the end of the fabric from jumping back, or buckling when the knife cuts off a section. This roller 26 is important for the reasons last mentioned and 1S adjustabllin slotted guides 26 to permit it to be'm'oved back and forth len thwise of the machine so that when' the 'clot -is temporarily at rest; being still held by the rollers 22-23 but supported on the constantly running tapes 25, the roller which also runs constantly by reason of its engagement with the tapes, can be shifted so that it will not rub over the freshly printed ortionof the cloth and possibly blur the rand or smear the fabric.

23 is a'frame, felt-lined on its under side and slidable on a suitable guide 23 and movable lengthwise. of and in contact with the" upper feed roll.23. It is for the purpose of wipin ofi the ink that may possibly colle'c't on t'e roll from the freshly imprinted fabric.

Beyond the cutter the severed and printed Section d of the strip D is received on to the constantly running t. pes 27 and carried across the transversely extending bars 28 between which the vertically reciprocating folding blade 29 o crates. The front end of the severed stri is caught by a succeeding setof constant y running tapes 30 and cari he fabric asses around a suitable tension device 20 an thence around erases ried against an adjustable stop bar 31 which trues the front edge of the strip. As the severed strip contacts with bar 31 the blade 29 descends and folds the strip'lengthwise in The carriage may be locked in anydesircd position by appropriate means. The importance of the adjustability of the folder with regard to the cutting and printing mechanisms will e pointed out later.- I desire to say now that special stress is laid on the fact that this machine is strictly adjustabie in all essential particulars.

Stop bar 31 is adjustable on carriage c and is essential since both carriers 2730 run constantly and without the bar the severed section would be carried toofar or be thrown askew so as not to be folded in the middle. The adjustment of the bar to the folder is ro ortioned to the distance between the on an adjustable frame of carrier 0 330 01 er and cutter, and both depend on and vary according to the size of the bag to be made Referring to the driving connections: Power is derived from the main shaft 60 operated from any suitable source. A gear on shaft 60 engages another gear on the counter-shaft 61 whence extends a sprocket chain 62 to a sprocket on shaft 63. From shaft 63, a chain 64 runs to shaft 65 on the printing press, whence the form and impression cylinders, inking and feed rolls are operated. Also from shaft 63 extends a chain 66 to a sprocket 66 geared to one of the rolls 2 which operate the unwinding of the material from roll A. Also from shaft 63 runs a chain 67 to a sprocket. on shaft 68, whence power is transmitted by the respective connections 69 and 70 to run carriers 25, i

27 and 30. Tapes 27 are crossed and pass around the three rollers 27-i27-27". The lower roller27 is adjustable in vortically slotted guides 27 on a fixed part of frame C; roller 27*"- is journalcd in a fixed every essential part should be positively driven, thereby'preventing disarrangcmentthe printing press and to the cutter are intermittent, the operation of the several endless carriers 2527-3034 and 36 is continuous.

The several driving connections are gither chains and sprockets, or gears in order, that after the machine is once adjusted for a particular run of bags. 3'

In operation a roll of cloth A is taken, the

' width of the cloth being equal to the length of the bag to be made. Cam 7 is adjusted so that its period of non-contact with the roller being mounted on rollers properly on-arm 9 will allow the rolls.5-6 to operate just long enough to' feed the exact quantity of cloth through the press as will constitutethe width. of a severed bag blank before itis folded. Theposition of the press relative to the cutter 24 is then determined; the press 108 for this purpose and being movable back and forth by suitable means as the screw and hand-wheel 109. The throw of the connecting rod 7 9 is then adjusted to render the feed by the rollers 22-23 to the cutter proportionate to the feed through the printing-press, since there is seen to be a necessarily coordinated'moyement between the printing and the cutting and folding mechanisms. The folder is then adjusted towards or from the cutter according to'the size of the bag,- and the stop bar 31 is setat such point as to bring the b ade exactly in the middle of the section to be folded. a v

It is essentialto a commercially practicable machine, as I have found by lon experience. that'the folding mechanism e adjustable as a unit to and from the cutting mechanism. In fact it isimpossibleto folda large bag if the folding mechanism is fixed close to the cutter as bags. Conversely it, is impracticable to fold small ,bags if the folder'is set permanentlyat a point necessary to correetly fold thelargest bag which the machine is capable of cutting, and for the following reasons: Assume the folder is fixed at a point which would enable the folding of a bag 0011'- of cloth. The folder blade in this-ease-would have to bels'ituated at least 17-- from the cutting blades. Now supsg that when the folding mechanism is situ at this distance from'the cutting blades it iscloth. The. folding device would be adjusted put it was three'inches from the-cutter,

desired to cut a "bag containing six inches of the stop bar 31 would be'fshifted to bring thefolder in the middle of'the strip to be sev cited, and the cam 7 adjusted so that its pe-- riod of contact with the roller on arm 9 would allow the rolls 5- 6 to operate just long enough tofeedthe exact quantity of cloth thrpu h the press as would co fi yi illl the width 0 the severed bag hlankbefcieiit V itshould be for small l is folded. The position of the press relative to the cutter would be adjusted, and the length of the connecting rod 7 9 also adjusted so as to render the feed by the rollers 2223 to the cutter proportionate to the feed l through the press, as previously described. There is thus an adjustment of two of the three essential mechanisms in this printing, cutting and folding operation, towards or from the third. severed, if the it ling blade is situated 17 from th uttin blades, it will he observed that the end of the 6 length would be 9 from the folding blade, and in order to be 3 beyond the blade. Following the cutting blades is the small roller 27 and attached to the fol(ling-blade-frame cis a similar roller 27*. These rollers carry the tapes 27 which conduct the cloth frornthe cutting blades to the folder as before described. At the rear side of the folderarc the rollers 30 for supporting the tapes 30 which operate continuously beyond the folder. There is a s ace of five or six inches between the front ro ler 30 and roller 27 on the folding blade frame. It will'be perceived that if the cloth is severed in 6 lengths, that there would be nothing to carry it across the space between these two rollers and bars 28. In other Words the part of the strip to be folded must be projected across this space throu h the agency of the unsevered web. So u ess the folding blade frame. were adjustable to and from the cutting blade, it would be impossible to prop- Qerly fold bags of a variety of sizes.

. The feed rolls 22- 23 and the carrier'bolts 25 preceding the cutting mechanism, assist the continuously moving carriers 27-30 res ectivelybetween the cutting and folding b ade and ,beyond thefolding blade, by pushing the fabric forward beneath the folding 'bladeand onto both carriers 27 ?0.- This pushing of the fabric by the feeding rolls and the" carriers receding the cutting blades is essential to t e practical operation of the ma- -cl n'ne J Y I have iii-successful operation, machines which are adjustable to cut and foldbag sections from 6 to 34 in width. When these sections are folded they make bags respectively from 3 to 17" in width.

The feed of the cloth to the cutter and folder is intermittent like that to the press but is alternative with and at a different rate of speed than the latter. I That is the amount of material. coming from-the press aftereach imprint will exact y equalthe amount going to the cutter at each actuation of the tellers 22'- 23' yet at the actualtime of the forward movement of the cloth through'the press and .to'thecutter, the rate of speed through the cutting machine is greater than throu h the -printingspress-due tothe differences int c retive steed-operating means. It is obvi- After the length has been folded properly it would have to be carried ous therefore, that if the cloth were fedsimultaneouslyinto each, and not successivelyor.

alternately, there would be -againof the feed into the cutting machine over that by theand severalimpressions of the printing plate;

This separation of the press and the cutting and folding mechanisms is'to 'permit'of the adjustment of one mechanism relative to the others, that must be made in printing bags of different sizes; since the distance from the cutting bladeto the oint of contact on'the' cloth of the side of t e rin'ting late mustbe definitelyfixed in or er that t e print on the section to'be severed bealways properl" disposed relative tothedistanoe from eac edge of the folded seetion. In other words the rint on the cloth must occupy a definite un' orm position relative to the-cut ed e of the cloth hence with a continuous; strip avmgsuccessively applied brandsdlecut must always occur on -precisely the'same line.
