1 ENVELOPE MACHINE A Filed May 8, 1931 www Patented May 31, 1932 UNITED STA-TES PATENT OFI-ica WILLIAM zonen, or Norm, New maar, `V4assreavon. To :.Eo s'roNE', or Bnocx'rolv,

The present invention relates to envelope machines in which webs are led from a pair of paper rolls disposed one above the other and transversely cut `to form oppos1te [E pairs of blank sections adapted to be assembled and secured together to form two-part envelopes closed along their side and bottom edges and having open sealing iaps attheir top or mouth.
The objects of the invention include an envelope construction in which little or no waste of paper-stock is formed, and by its two-part blank formation the production of the machine is substantially doubled as compared 15 with the common one-piece envelopes of the side seam type of similar sizes.
For further comprehension of the invention, and of the objects and advantages thereof, reference is had to the following descrip- 9 tion and accompanying drawings, and to theV appended claims in which the various features of the invention are more particularlyy set forth. Referring to the drawings in which simiu lar characters of reference designate like parts throughout the several views:
Figure 1 is a diagrammatic side elevational view of a machine embodying my invention.
3 Figure 2 is an end elevational view of the machine.
Figure 3 is a face view of the upper. web showing the general shape into which the front blanks of the envelopes are cut during transit, together with gum lines thereon.
Figure 4'is a face view of, the lower web showing the relative cutting shape of the back blank and dotted score lines indicating side seam folding lines.
Figure 5 is a plan view of a folded envelope as delivered from the machine, showing the back member partiall broken away to expose a. portion of the fol ed seam thereof and the relative position of the gum line on the inner face of the front member.
In the drawings numerals a and 11a rey spectively indicate u per and lower paper rolls of different wi ths centrally disposed transversely in line with each other and ar- 50 ranged with conventional tension devices, not
1981. serial lo. 585,919.
The upper web 10 leading from the paper roll 10a is of relatively narrow Iwidthand passes between a pair of feeding rollersv 13 from which point it continues its travel ata uniform velocity between the pair .of sidecuttingrolls 14 and 15, respectively provided with detachable side-cutting discs 14a and 15a, the former arranged with knife members 146 and the latter with hardened surfaces that coact with the knives to trim the oppositeside edges of the web and form beveled portions thereon as indicated at 140, Figs.v 3 and 5. The chips formed by the side-cutting rolls may be removed from the machine in well-known manner, as by an air-suction device.
between a pair of cross-cutting rolls 16 and 17, the latter arranged with a pair of knives 18 extending lengthwise of the roll and adapted to coact wit hardened surfaces on the opposite rollr16 and transversel sever the web alon the line 18a, Fig. 3, an form front envelope lanlrs 194 having end extensions constituting top and bottom sealing flaps 19a and 196 respectively. In passing around the cutting roll 16, the partially severed blanks 19 are engaged by the gumming roll 20,'having at opposite ends the discs 21 adapted to appl longitudinal gum lines 21a to the blan the gumming roll being also providedw with die sections 22 for appl `ng transverse gumlines 22a to the bottom ap 196. Adjacent the gumming roll 20, a -supply box 23 is conveniently supporte and rovided with a rotary feed roller 24 that adiustably engages the gum supplyingmembers ofthe gummingroll and regulates the quantity of adheslve applied thereto, the several parts of the gumming device beingarranged in well-known manner.
The lower web 11 leading from the paper roll 11a is of relatively wider ,width than ythe upper web and passes bet-Ween two pairs df' feeding rollers and 26,"and intermediate of said pairs of rollers the opposite side edges 70 From the side-cutting rolls the web vpasses of the web are'- folded over upon the body ortion thereof along the dotted lines 27, see
ig. 4, to form side connection seams 27a, the side folding device including a fixed transverse spacing bar 28 over which the seams are drawn andfolded downv by the longitudinally extending side folding blades 29 dur- -i in the regular movement of the web, the said "transversely sever the side the line 32a, Fig. 4, and form back envelope si e ,seam foldin device being of well-,known construction. rom the feeding rollers 26 the lowerweb passes between a pair of cross cutting rolls 30 and 31, the latter roll being arranged with a pair of knives 32 extending lengthwise thereof and adapted to coact with hardened surfaces on the op osite roll 30 and fblded web along blanks 33 having a width over the folded side seams corresponding with the body width of the front blanks, and the length of the back blanks corresponding with the body length of the front blanks, as disposed between the end sealin fla s thereof.
In t e ormation of the different lengths of blanks herein shown, the separate pairs of transverse cutting rolls therefor are diametrically proportioned to respectively make two blanks at each revolution, and in their rotative movement the rolls are geared to make a common number of turns and succeslsively present a front and back'blank at regular intervals,I thus necessitating a relatively slower speed for the lower web than for the upper one. From the pair of cutting rolls 30 and 31 the back blanks 33 are directed upwardly between the guide bars 34 for env gagement bythe pair of feed rollers 35, and
from which the blanks are directed upwardly between the guide bars 36 and the pair of feed rollers 37 and 38, which rollers are rotated at a feeding speed common with that of the cutting roll 16, that also advances the front i ting rolls 16 and 17 and the feeding rollers 37 and 38 are geared together by driving wheels on their respective shafts and afford a common feeding speed for the two-part blanks, the backi blanks being suitably' guided upwardly around the feeding roller 37 for collecting engagement with the cutting roll 16.
In collecting the back and front blanks together the latter are advanced with the top flaps 19a in the lead, on which no gum is applied, and in their advancement around the cutting roll 16 the front blanks engage the gumming roll 20 and first receive the longitudinal gum lines 21a upon the body of the blanks, and then the transverse gum lines 22a upon the bottom flap 19?), the blanks 19 being then downwardly directed by guide r'bars 41 around said cutting roll and timed to effect registration with the upwardly moving opposite back blank 33 and the engagement between the side seams thereof and the gum The two-part blanks as thus secured t0- gether with their top flaps 19a left open, are advanced between the two pairs of pressure rollers 44, from which they are fed in overlapping relation between a pair of endless ressure belts 45, carried upon slowly rotating rollers 46, and from which belts the work is delivered upon the table 47.
As herein shown the operating parts of the machine are driven from the motor 48 by a small ulley 49 fixed to the driving shaft thereof and having a belt 50 leading to a relatively large pulley 51, fixed upon a stubshaft 52 journaled in a bearing 53 mounted on a side frame of said machine, the stubshaft being fixedly provided with a relatively small sprocket wheel 54 having a chain 55 leading to a relatively large sprocket wheel '56, fixed upon a shaft 57, on which is secured the cutting roll 16 and the gear wheel 58, the latter in turn driving the adjacent rolls and guln wheels in the directions shown by the arrows in Fig. 1, the remaining rotating parts being likewlse driven indirectly from the same source of power.
