WEB FEEDING AND PASTING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 624,308, dated May 2, 1899.

Application filed Ma 15, 1897.

T0 aZZ whom, it may concern:

Beit known that I, LUTHER 0. CROWELL, a citizen of the United States, residing at New York, (Brooklyn,) county of Kings, and State of New York, have invented certain new and useful Improvements in Web Feeding and Pasting Mechanisms, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

The main object of the present invention is to provide an improved feeding mechanism for feeding a web forward in proper time to secure the uniform timing and positioning of sheet lengths thereof, and more particularly to secure the proper timing of the feed of the web with relation to cutting devices by which the web is divided into sheets or to other mechanisms.

While the invention is generally applicable wherever it i's'desir'edto feed forward a web and time the sheet lengths thereof accurately, it is especially designed for use in wrappingmachines, such as machines for wrapping newspapers and other publications for mailing, in which wrappers are printed with addresses or other matter, and it is desired that such printing shall occupy substantially the same position upon each. of the wrapped papers or other articles. The desired result is secured in constructions embodying the present invention in the preferred form by providing the printed wrapper web with openings formed by notches or perforations, which may conveniently be punched or cut out simultaneously with printing and which 00- cupy substantially the same position relatively to the printed matter on each wrapper and employing a feeding mechanism arranged to control the feed of the web by these openings, so that accurate timing of the successive sheet lengths is secured. For this purpose I preferably employ a feeding mechanism capable of feeding a little more paper than the distance between the openings in the web, so as to provide for anyirregularities in the distance between the openings and actuate the feeding devices by mechanism preferably frictionally driven and having a detent controlled by a finger supported by the web, so as to drop into the successive openings in the web and'controlling the detent, so as to stop Serial No. 636,649. (No model.)

the feed until the relation of the opening and wrapper length to the cutting-cylinders or other mechanism is that desired, when the detent is released and the finger lifted from the opening, permitting the web to be fed forward until the finger drops into another opening.

In a roll of paper the paper is not always even at the edges, and this unevenness causes the paper to wrinkle as it enters between feedrolls, such as are preferably used for feeding the web in machinesembodying the invention above generally set out-that is,.one of the pair of rolls being cut away or formed of disks, so as to engage the web only near its edges. To overcome this diificulty, I use a driven belt acting upon the outside of the web-roll to unwind it at such a speed that the paper may be slack when it enters the feedrolls, and thus adjust itself to them, so as not to wrinkle.

The invention aims, further, to provide in connection with the feeding mechanism a pasting mechanism, hereinafter fully described, whereby a line of paste is applied accurately at the edges of the successive sheets, which pasting mechanism forms in itself a feature of the invention and maybe employed in other connections.

For a full understanding of the invention a detailed description of a construction embodying all the features of the same in the preferred form will now be given in connection with the accompanying drawings, forming a part of this specification, and the features forming the invention then specifically pointed out in the claims.

In the drawings, Figure 1 is a side elevation of a feeding mechanism designed for use in feeding wrappers to a wrapping-machine and applying a line of paste thereto. Fig. 2 is a front elevation, on an enlarged scale, of the feeding devices with'the friction-clutch shown in section. Figs. 3 and 4 are detail end elevations of the feeding devices further enlarged and partly broken away to show the construction and showing the parts in two positions. Fig. 5 is a section on the scale of Fig. 2, taken on line 5 of Fig. 1, showing the devices for adjusting the speed of the belt. Fig. 6 is a detail central section, on the scale of Figs. 3 and 4, of the clutch construction and feed-roll support. Fig. 7is a d tail ie taken inside the frame in Fig. 1, showing the feeding and cutting rolls and pasting devices.

the edges of the successive sheets, as hereinafter described, and thence between feedingrolls 13 and between vertical guides 14. There is thus formed a complete wrapper feeding, cutting, and pasting mechanism, from which successive wrappers may be received by any suitable wrapping mechanism.

Referring now in detail to the feeding devices, and first to those features of construction which especially have to do with securing accurate timing of the sheet lengths, the feed-roll A is mounted in suitable bearings, being shown as supported at one end on an adjustable cone-bearing 20, entering-a bushing in the end of the cylinder, and at its opposite end being splined to a sleeve 21, mounted in bearings carried by a bracket 22, adjustably supported on a bar 23 at the top of the frame of the machine. The sleeve 21 carries a ratchet-wheel 24 and one member of a friction-clutch, this member consisting in the form shown of a spring-pressed bar 25, mounted in a recess in a stud forming the end of the sleeve, this bar having at its outer end three ridges having inclined sides, each engaging corresponding circumferential grooves in the interior of a disk 26, carried by or secured to a gear 27, mounted on a stud 28 on the frame. This gear 27, with the disk 26, is positively and continuously driven from any suitable part of the machine, but preferably from one of the cutting-rolls O O, as

from the roll 0, through an intermediate 29,

as shown.

The feeding or friction disks B, which coact with the feeding-roll A, are carried by arms 30, adjustably mounted on the bar 23, previously referred to, so that these disks which engage the web at or near its opposite side edges may be adjusted toward and from the roll A, so as to secure just the feeding pressure desired, and longitudinally of the roll A, so as to engage the web at the proper points.

Above the feeding-roll A is mounted in suitable bearings a rock-shaft 31, carrying an arm 32, having at its end a finger a, adapted to enter the openings in the web. This shaft carries a second arm 33, provided at its end with a pawl or catch 1), which acts to engage the ratchet-wheel 24 to stop the rotation of the sleeve 21 and roll A. The finger a rests upon the web under the pressure of the weight ofthe arms 32 and 33 and is positioned opposite a groove 1 in the feed-roll A and in line with a series of perforations 2 in the web, which, as above stated, are punched one to each wrapper length and in a certain fixed relation to the printed matter on the latter. These perforations are preferably slightly elongated transversely of the web to insure the desired action even though the line of feed of the web should vary slightly.

The finger a, and the pawl 19 are so arranged relatively to each other that when the finger is supported by the web the pawl 19 is held out of contact with the ratchet-wheel 24; but when one of the openings 2 in the wrapper comes opposite the finger a and the latter drops into the same and into the groove in the feed-roll the pawl 19 also drops into contact with the ratchet-wheel and engages one of the teeth of thelatter, so as to hold the sleeve 21 and the roll A against rotation by the friction-clutch.

For the purpose of raising the pawl 19 out of contact with the ratchet-wheel and for withdrawing the finger a from the hole in the wrapper, so that the feed-roll A may again rotate to feed the web y, the arm 33 carries a roll 34, which runs upon a circular plate or cam 35 on the constantly-rotating disk 26, this plate or cam being cut away for a short distance, so as to allow the pawl and finger to drop, as previously described, and having upon the rear side of this opening an inclined surface 36, which acts to raise the arm by contact with the roll 34, and thereby raise the pawl 11 and the finger a, when the disk is rotated onward the short distance required to bring this cam-surface into contact with the roll 34. The operation of this part of the construction is briefly as' follows:

The feed-roll A and 'coacting disks B feed the webforward when the arm 33 is raised to hold the pawl I) out of contact with the ratchet-- wheel 24, so as to permit the friction-clutch to rotate the sleeve 21 and roll A. Just before a wrapper length has been fed forward the disk 26 in its rotation brings the cutaway portion of the plate or cam 35 opposite the roll 34, so as to leave the arm 33 free to drop to bring the pawl 19 into contact with .the ratchet-whee1,whicl1, however, it is prevented from doing by the finger a resting against and being supported by the Wrapper. By the further movement of the roll A, however, the wrapper-web is moved so that one of the openings 2 comes opposite the finger a, and the latter then drops through the wrapper into the groove 1 in the feed-roll, and at the same time the pawl 5 drops into contact with the ratchet-wheel and catching one of the teeth of the latter stops the rotation of the sleeve 21 and the roll A. The feed of the Web is thus stopped until the inclined surface 36 of the plate or cam 35 strikes the roll 34 and raises the arm 33 to carry the pawl b out of contact with the ratchet-wheel 24 and to rock the shaft 31 to raise the finger at out of the opening in the web, thereby permitting the roll A to be again rotated under the action of the friction-clutch and releasing the web to allow it to be fed onward. It will thus be seen that the commencement of the feed of each wrapper length is controlled so as to occur at a certain time relatively to the movement of the continuously-driven disk 26, and

the disk 26, being driven from the cuttingrolls C O or so as to have a fixed relation in its movement of rotation to that of the cutting-rolls G each wrapper must have the same relative position with respect to the'cutting-rolls C 0 when received thereby, thus 7, insuring the accurate timing of the successive wrappers with the cutting-rolls and succeeding mechanism. This result necessarily follows from the fact that the commencement of the feeding of each successive wrapper length is determined by the contact of the cam 35 on the continuously-rotating disk 26 with the roll 34 on the arm 33.

By making the feeding-rollA of such size that it will feed forwarda little more than a wrapper length at each complete rotation and by arranging the disk 26 to make a complete rotation for each wrapper length to be fed, orin the machine shown a complete rotation for each rotation of the cutting-rolls'C O, the machine is made to compensatefor any irregularity in the distance between the openings 2 in the wrapper-Web y, as will be readily understood. It will be understood that instead of having the cam or plate 35 extend nearly around the disk 26, as shown, it may extend only far enough to allow the wrapper-web to be advanced sufliciently to carry the opening 2 beyond the finger a, after which the finger a, resting on the web, may be depended upon to hold the pawl l) away from the ratchet-wheel 24 until the next opening 2 comes beneath the finger, and

the roll A is again stopped,as before described.

It is evident that the machine may be readily arranged to feed a wrapper length at each half or quarter rotation of the disk 26 or otherwise, as may be desired, instead of at each complete rotation, as in the preferred construction shown, the roll A being in any case of such size as to feed a little more than a wrapper length at each full, half, or quarter rotation, or as the case may be.

The tension and take-up roll 10 serves to take up the slack in the web which would otherwise result from stopping the feed-roll A, the web y being continuously fed from the roll Y in the machine shown.

While in the preferred construction shown and described for carrying out the invention thedevices for interrupting the feed of the web are controlled by a finger adapted to enter openings or depressions in the web, and while this construction is preferred and in itself forms an important feature of the invention, yet it will be understood that in carrying out the idea of controlling the devices for interrupting the feed of the web by a series of devices on the web I am not to be limited to the use of openings or depressions in the web and a finger adapted to enter such openings or depressions, but that I may provide the Web with other devices adapted to control the feeding devices through suitable intermediate mechanism.

I have used the word controller in the claims to designate such devices on the web. By the term controller, therefore, as used in the claims is meant any perforation, notch, depression, elevation, or any device whatsoever on or in the web which is adapted to move a member or release or otherwise allow such member to be moved.

Referring nowto the second feature of'the invention, for the purpose of preventing wrinkling of the web as it enters between the roll A and the feeding-disks B a positivelydriven belt is provided,which engages the top of the web-roll Y and acts to unroll the web uniformly at such a speed that it will be slack when it enters between the feed-roll A and the feeding-disks B, the tension of the roll 10 bein g made so light that it does not interfere with this action, but leaves the web substantially slack, so as to readily adjust itself to the feedroll and feeding-disks when it enters between them. The belt D may be mounted in any suitable manner, so as to always engage the surface of the roll Y, and may be driven in any suitable manner; but in the preferred construction shown it is carried bya drivingroll 40, mounted in stationary hearings on the frame, and by a roll41, mounted in arms 42, extending out over the web-rollY and pivoted to the frame near the roll 40, so as to be free to drop, as the roll Y becomes gradually smaller as the wrapper-web is drawn off. For the purpose of adjusting the speed of this roll D so as to insure the accurate or approximately accurate feeding of the web the following construction is preferably used. The shaft of the driving-roll 40 carries a gear 44, which meshes with a gear 45, carried by a stud on the frame and having secured thereto a friction-disk 46, which engages the face of a friction-disk 4'7, mounted in a swinging arm 48, pivoted in a bracket on the frame. The arm 48 is provided with a segment 49, which is engaged by a worm 50 on a shaft mounted in an arm 51 and provided with a hand-wheel 52, by which it may be rotated to swing the arm 48 and shift the friction-disk 47, so that the disk 46 engages it farther from or nearer to the center of the disk 47, thus varying the speed of the disk 46, and consequently of the driving-roll 40. The frictiondisk47 is driven by gears 53 from a shaft mounted in brackets on the frame and which in turn is driven by bevel-gears 54 from a sleeve 55, mounted on a stud 56 on the frame, said sleeve carrying a gear 57, by which it is driven from a gear '75. The speed of the feeding-belts D may thus be readily changed to increase or decrease the speed at which the wrapper-web is fed from the Web-roll, as. may be desired.

Referring now to the means for applying a line of paste at one edge of the successive sheets, (shown in Fig. 1 and in the detail view, Fig. 7,) the feeding and cutting rolls C C are of the usual form, one of said rolls 0 carrying a cutting-blade 60, projecting from the surface of the roll and normally protected by a cushioned block 61, as usual, and the coacting roll 0' being provided witha longitudinal groove 62, coacting with the cutting-blade and formed, preferably, in a longitudinal block set in the roll in the usual manner. Just in advance of the groove 62, circumferentially of the roll, the roll is" provided with a longitudinal pasting strip or bar 63, which as the roll rotates receives paste from a rotating paste-carrier 64, which in turn is supplied from a fountain-roll 65, rotating in a paste-fountain 66. By this construction at each rotation of the cutting-rolls the pastingstrip 63, having received paste from the pastecarrier 64, will engage the web just in advance of the line on which the web is divided by the cutting-blade, so that each sheet divided from the Web as it leaves the cuttingrolls will have had a line of paste applied at its rear edge. The pasting-strip 63 forms, in effect, a portion of the surface of the roll 0 and may, in fact, be formed by a portion of the surface of said roll; but in order to prevent the paste received from the paste-carrier 64 from spreading circumferentially of the roll, as it otherwise would tend to do, the surface of the roll is cut away on either side of the pasting-strip, as shown in Fig. 7. It will be understood that the pasting-strip 63 and preferably, also, the paste-carrier 64 will be cut away or formed in sections, so as not to apply paste to the sheets at the points where they will come in contact with the guides 14. The feeding-rolls 13 are also preferably cut away or formed in sections, so as to engage the sheet only at points where paste has not been applied. The roll 0 is prefen ably cut away slightly opposite the paster 63, as shown at 3 in Fig. 7, so that paste will not be applied to this roll in case a rotation of the rolls and paster is made without paper between the cylinders to receive the paste.

By the above construction I provide a very compact and efficient pasting mechanism, whereby the line of paste will be applied with great accuracy at the rear edge of each successive wrapper length as it is advanced from the cutting-rolls. It will be understood that this feature of the invention is equally applicable in connection with devices whereby a web is perforated on lines on which it is afterward separated into sheets, as with blades which, completely sever the sheets, and the term cutter, cuttingblade, or cutting-roll as used in the claims is to be understood as including such perforating devices.

The moving parts of the machine, as shown, are driven from a shaft 70, which carries a gear 71, which meshes with a large gear 72,

which gear 72 carries a smaller gear 7 3, which meshes with the gear 75. The cutting-rolls C O carry intermeshing gears 76 and are driven from the gear 75 through an intermediate 77, meshing with a gear 78, carried by the roll 0. The paste-carrier 64 and fountain-roll are driven by the gear 7 6 of the roll 0, theshaft of the paste-carrier carrying a gear 79, meshing with said gear 76 and also with a gear 80 on the shaft of the fountainroll. The continuouslyrotating disk 26, which drives the feed-roll A, is driven from the roll 0 through an intermediate 29, as before described. The driving-roll40 for the belt D is driven from the gear 75 in the manner already described. The feeding-rolls 13 carry intermeshing gears 81 and are driven from the gear 71 through an intermediate 82.

It will be understood that the invention may be embodied in machines differing widely from that shown and also that many modifications may be made in the construction of the parts embodying the invention without departing from the invention.
