. Serial No. 197,028.

To all whom it may concern:

Be it known that I, ABRAHAM Novrox, a citizen of the United-States, and a resident of the city of New York county of Kings, and State of New York, have invented certain new and useful Improvements in Envelop-Blank Cutting and Forwarding Mechanism, of which the following, together with the accompanying drawings, is a specification. a f

The present invention relates to mechanism for cutting envelop blanks and the like from a continuous web or strip of material,

and for forwarding said blanks successively, for further operations thereon, such as gumming and folding. The present application constitutes a continuation of my copending application Serial No. 26,675, filed May '8,

1915, and allowed August 22, 1917.

The present invention contemplates the formation, with the least possible waste of material, of blanks for making the so-called high-back or high-cut envelops, from a continuous web of paper. Heretofore, in the formation of blanks from a continuous web, it has been proposed to form all the blanks in the same relative position to the web, which has resulted in excessive waste of stock, or else has confined this method to blanks substantially rhomboidal in form, suitable only for the so-called low-back or low-cut envelope. It has been discovered that blanks for high-cut or high-back en velops can be formed from a continuous web, with equal facility and without waste of stock, by disposing successiv e adjacent .blanks in relatively opposlte posltions with respect to the web. The present invention aims to utilize this advantage in the provision of a mechanism which first cuts oppositely disposed blanks from the continuously moving web, and thereafter causes all of said blanks to assume the same relative position, in readiness for movement in a uniform path for further operations thereon, as by a single set of folding devices.

The above and other objects are attainedby the mechanism which is set forth in detail hereinafter reference being had to the accompanying drawings, in which Figure 1 is a plan view of blank cutting and forwarding mechanism embodying my invention. r

Fi 2 is a longitudinal sectional view on Figs. 5 and' 6 are fragnientary lan views illustrating the operation of movigg a blank from its cut'position intoa position for further movement, in a uniform path, through the machine. 7

Figs. 7 and 8 are views similar to Figs. 5 and 6, showing the same mechanism in operation upon a different blank, the blank of Figs. 7 and 8 being formed from the web in an opposite relation to the blank of Figs. 5

and 6.

Fig. 9 is a, diagrammatic view, illustrating the manner in which the continuous web is cut to form the oppositely disposed blanks, and'the manner in which said blanks are turned, after cutting, to occupy the same relative positions for further movement in a uniform path.

Fig. 10 is a plan view of one of the web cutting devices used in the formation of the blanks.

Fig. 11 is an enlarged view illustrating oFne 011 the cutters employed on the device of ,Fig.-12 is a erspective view of a web severing device or separating adjacent oppositely disposed blanks.

Like reference characters refer to like parts in the different figures.

Referring first to Figs. 1 and 2, the mechanism is herein shown as carried between longitudinal side frames 1,- 1, which support at one end a shaft or reel 2 for a roll of material 3', from which the web A is continuously drawn. The side frames 1, 1 ro- 'vide journals for a main driving sh t 4 which carries a belt pulley 5 for actuation fromany sultable source of power, not

shown. The shaft 4' carries a' pinion 6' which is in mesh with'a gear 7 on a countershaft 8, the latter driving, through an idler 9, the intermeshingagears of a pair of feed rolls 10, 10 for advancing the web A through the machine. v v

In frontof the feed rolls 10, 10 are disposed a pair of cooperating cutting rolls 11,

I Specification of Letters Patent. P t te July 22, 1919 12, having intermeshing gears which are also actuated b the idler 9, as shown in Fig. 2. One of sai rolls, here shown as the roll 12, carries cutting devices 13, 14, .F i 10, for operation on the continuously trave ing web A to blank out the gore shaped pieces 13',

14/, Fig. 9, inthe formation of the blanks from said web. Said roll 12 also carries cutting devices 15 and 16, to blank out the reentrant angles 15, and 16', Fig. 9, in the opposite edges of adjacent blanks. Said roll 12 also carries a cutting device 17, Fi 2' and 11, and in alinement therewith a palr of devices 13 and 19 Fig. 2, similar to the devices 15 and 16, for blanking out the aperture 17 and the rentrant angles 18 and 19' in the web A, as shown clearly in Fig. 9.

The above described cutting devices on the roll 12 preferably operate in opposition to a hardened surface 20 on roll 11, and each 0 cle of operations thereof serves to form tile cuts 13, 11', 15, 16, 17, 18 and 19 in thewe'b A.

The above described cutting operations are ordinarily not suflicient. to remove the waste material or chips from the web, since all the'fibers of the material are not completely severed. For the removal of said chips, any suitable 'chip removing mechanism may be employed, 'such as that shown and described in my copending application Serial No. 182,025, filed July 21, 1917. As

herein shown, apair of chip removing rolls 21, 21 have intermeshing ars driven from .an idler 22, which in turn is driven from the roll 12 of the blank cutting mechanism; said rolls 21, 21 are shown as nipped with mechanism for withdrawing t e waste material .or chi s reviously formed in the web at 13', 14', 15-, 16, 17',-18 and 19, but since said chip removing mechanism forms no part of the present invention, a detailed description thereof is unnecessary. As the web emerges from said chip removing rolls,

it presents the appearance indicated near the center of Fig. 9, and in this condition it is carried forward between the bight of forwarding rolls 23, 23, which have intermeshin gears driven from an idler 24, that is driven in turn from the lower chip removing roll 21.

' In advance of the forwarding rolls 23, 23 are provided web severing rolls 25 and 26, one of which, in the present instance the roll 26, carries cutting devices 27 and 28, as

shown in Fig. 12, for severing the web on the the cutting device 27 will across the web and thereby produce a shear mg action which insures complete 'severanae of the fibers. .The cutting rolls 25 and 26 carr intermeshin gears, and are driven by an i ler 29. which in turn derives its rotation from the lower web, forwarding roll 23, as shown in Fig. 2. The action of these outt1ng rolls 25' and 26 is such that the blanking out of the web into a succession of oppositeFly disposed blanks is completed, as shown in ig. 9, and as also shown in said figure, theblanks emerge from said rolls in alternat ng relation, viz., first a right hand blank, so-called, as indicated at 30, presenting an advancing edge which is oblique, and then a left hand blank, so-called, as indicated at 31, presenting a transverse edge, with its oblique ed erearmost.

ach blank thus severed from the web by the cuttin rolls 25 and 26 is immediately seized by orwarding rolls 32, 33,which operate at a higher speed than the web forwarding rolls 23, 23 so as to space each severed blank from the advancing edge of the web, as shown at 34, 34, Fig. 9. With'the blanks thus severed and separated, it becomes necessary, if they are to be further acted upon by the same mechanism, to dispose them all in a uniform position for further advancement, and to this end the invention contemplates the provision of a suitable blank turning mechanism for action upon the oppositely disposed adjacent blanks 30 and 31 to bring them into a uniform position. To prevent interference with the operation of this blank turning mechanism, which will be described hereinafter, one of the forwarding and accelerating rolls, in the present instance the roll 32, 1s preferably made with a segmental cutaway portion 35, in orderto insure therelease of the rear edge of a blank as soon as its forward edge comes under the influence of the turning mechanism. The rolls 32 and 33 have suitable intermeshing gears which are driven from an idler 36, the latterin turn deriving its rotation from the forwarding roll 26, as shown in Fig. 2.

From the forwarding rolls 32 and 33, each severed 'blank 30 or 31 passes between pairs of fingers 37 and 38. The lower fingers 38 are stationary, while the upper fingers are carried on a rock shaft 39 which is actuated by an arm 40, having a cam roll bearing against a cam 41 on the shaft of segmental roll '32. The action of this cam is such that the fingers 37 and 38 remain separated while the blank is under the influence of rolls 32 and 33; thereafter, as the blank passes into the 'blank turnmgmechanism, as hereinafter described, the earn 41 allows the gradually cut fingers 37 to descend and rest by gravity on the blank, to retard the same and reduce its ;momentum, prelin iinary to the turning operation. The disks 42 and 43, in advanceof said fingers, have suitable intermeshing facing turning members'46 and47 which are normally spaced apart to receive the blank in the plane of its forward movement by the disks 42 and 43, the lower member 46 beingvertically fixed and the uppermember' 47 being capable of'movem'ent toward and away from the member 46,.as hereinafter described. The vertical movable mem-- ber 47 has a spindle 48, which is journaled in the upper part of framework 45 and is capable of axial movement therein. A spring 49, acting between the member 47 and the stationary bearing of spindle 48, tends to yieldingly press the member 47 toward the member 46, and this .action'is opposed by a lever 50 pivoted at 51011 framework 45, and bearing upwardly against a nut 52 is pivoted at 55 and carries a cam roll 56 foron the upper end of spindle 48. The opposite end of lever 50 is pivotally connected bya link 53- with a swinging arm 54, WhlCh coiiperation with a. cam 57 on the shaft of disk 42. The high part of cam 57 maintains the member 47 in elevated position until a blank is disposed between the members'46- and 47; thereafter the cam allows the spring 49 to depress the member 47 and thus to grip the blank against the member 46, preliminary to the turning operation.

For the accomplishment of this turning operation, the members 46 and 47, when in position to clamp the blanks as abovedescribed, are given predetermined joint movements of oscillation, in one direction to rotate a right hand blank 30 into the desired position, and in the other direction to rotate a left hand blank 31 into the same position. To this end'the spindle 48 of member 47 is adapted to be oscillated in unison with a vertical fixed'spindle 58 attached to member 46 and having a journal bearing in the lower part of framework 45 The two spindles 48 and 58 have similarly disposed rock arms '59, 59 extending radially therefrom,

- the rock arm for the vertical movable spindle 48 having a spline connection which permits axial movement ofsaid spindle for the purpose above described. The ends of arms 59, 59 are connected by links 60, 60 to arms 61, 61 extending from an actuating rock shaft 62 which is journaled in the framework 45; Said actuating rock shaft 62 is oscillated by means of a rock arm 63, whose free end carriesa cam roll 64 in the cam groove 65 of a rotating horizontal disk 66. v Y z The disk '66 is suitably supported by a yokebrubearing 67 carried inwardly from the front side l, andv is operated by bevel gearing 68 from a transverse shaft 69 which derives its rotation, through gear 70, from the idler 44, as shown in Figs. 2 and The contour vof cam groove 65 is such that upon the'disposal-of a right hand blank 30 between the members 46 and 47, as shown in Fig. 5, and the clamping of said blank between said members, the actuating shaft 62 w1ll be rocked to move thespindles 48 and 5 8 ma clockwise direction, and thus to carry said blank into the position shown in. -Fig. 6, Thereafter, ma ntains the members 46 and 47 againstro the contour or groove 65 tation while the membe1-47 is being raised by spring 49 to release said blank 30, and to permit the'removal of said blank by. rolls'7J and'72, as hereinafter described. With the turning mechanism-in this condition, a left hand blank 31- is then projected between the members 46 and 47, as shOWnin Fig.7 and thereafter, upon the clamping of said blank by the descent of member 47 the cam groove 65 causes the actuating rock shaft 62 to move counter-clockwise, thus carrying the left hand blank 31into the position illustrated-in Fig. 8,'which is the same relative sition as that shown in Fig. 6 for the-right r and blank 30. The blank turning mechanism thus operates in opposite directions upon successive adj accnt oppositely disposed b anks to move them into the same relative positions with respect to the rolls 71 and 72. The arrival of 'a blank between the members 46 and 47 in position for the inauguration of the above described turning movement, is substantially coincident with the release of said blank by the disks 42 and 43, owing to the provision of a segmental cutaway portions 73 in the disks 42. That is to say,'the disks 42 are so timed and proportioned that their edges 74 release the blanks 30 and 31 when they arrive in the proper position to be turned, as illustrated in Figs. 5 and 7 respectively, and at this instant, in each case, the finger 37 descends upon the rear edge of the blank to arrest its further movement. The turning of a blank as above described draws its rear edge from beneath the gravity resting fingers 37, and this turning takes p ace while the segmental cutaway portions 73 of disks 42 are moving over said blank.

. The rolls 71 and 72 which receive the blank from the turning mechanism are disposed parallel with the longer axis of the blank in the position occupied by said axis after the turning movement is completed. Theserolls have .intermeshing gears to insure their rotation in unison, and are jourthe roll 72 to remove the blank from the ,t

turning mechanism and to advance the same into the bight of cylindrical rolls 77, 77 from which it may pass onto belts 78, 78, or other suitable mechanism for conveying it forward for further operations. Thus all of the blanks are turned into the same relative position with respect to the machine, and are capable of being moved forward; in the same path for further operation thereon, for instance, by a single set of gumming and folding devices, notwithstanding the initial disposition of said blanks in opposing relation, as originally cut from the web A. In other words, as shown in Fig. 9, all the blanks are finally caused to move in the direction indicated by the arrow B, in the same path, and with their extended flaps disposed symmetrically with respect to the line of travel, whereby the several reentrant angles defining the lines of fold of the completed envelop, become available for centering and squarin the blanks preliminary to the operation 0 the single set of gumming, creasing and folding devices, just as though the blanks had been fed uniformly from a stack or pile.

For drivin the rolls 77 and belts 78, a counter-shaft 9 is suitably journaled on the front obli ue-frame member 75, said countershaft having a bevel gear connection 80 ,with a shaft 81 that is driven in turn by bevel gearing 82 from the main driving shaft 4:. The shaft 79 drives the rolls of belts 78 through bevel gearing 83, and the intermeshing gears of rolls 72 and 77 may be driven therefrom through idlers 84 and 85, as shown in Fig. 2.
