METHOD AND APPARATUS FOR MAKING HIGH SPEED PASTERS Filed Aug. 24. i931 3 Sheets-Sheet 5 @ff f ef/704% @fthe ifa/2 Patented Oct'. 2, 1934 UNITED STATES PATENT OFFICE METHOD AND APPARATUS FOR MAKING HIGH SPEED PASTERS 1o is to provide a simple and effective method and an eicient apparatus for making high-speedl pasters without requiring complicated mechanism or conditions of operation which are too diicult for the ordinary newspaper or other printing plant in which the invention is intended to be used.

Other objects and advantages of` the invention will be apparent from the following description, which, taken in connection with the accompanying drawings, discloses a preferred embodiment thereof.

Referring to the drawings,

Fig. 1 is a sectional and elevational view of an apparatus in which my invention is embodied, the same being particularly adapted for carrying g5 out the method which constitutes a part of the invention;

Fig. 2 is a sectional and elevational view taken substantially on line 2-2 in Fig. 1, certain parts in this view being broken away for convenience 3@ in illustration;

Fig. 3 is a broken view corresponding to Fig. 1, but showing a somewhat modified form of apparatus; and

Fig. 4 is a reduced perspective view of a web roll showing the means employed for holding the leading edge of the web tightly against the roll for a purpose which will hereinafter be described.

On said drawings I have shown for purposes of illustration two side-frames 11 and 12 spaced apart sufficiently to permit the positioning of rolls of paper lengthwise therebetween, three rolls, identified, respectively, by the

reference numerals

13, 14 and 15, being shown in the present instance and being carried by chains 16 located in channels 1'7 in the side-frames, said chains comprising links 18 and rollers 19 and being adapted to be driven in any suitable manner as by sprockets 21 driven from a source of power which will presently be described. The chains at spaced intervals are provided with chucks 22 for rotatably supporting the rolls of paper, said chucks being adapted to enter the cores 23 of the rolls in the usual manner as shown inFig. 2 of the drawings. The chucks shown at the left in Fig. 2 are movable longitudinally to permit the chucking of the new rolls and the removal of the cores of the exhausted rolls. Any suitable construction may be employed for this purpose, the chucks being shown as splined on a supporting shaft by means of a pin 61, a collar 62 being carried on said shaft and having 60 a spiral groove in which the pin 61 rides when said collar is rotated. For the purpose of rotating the collar a pivoted lever 64 may be employed, the lower end of said lever being in the form of a toothed segment 65 meshing with teeth 66 pro- 65 vided on the collar 62, it being understood that rotation of said collar by operation of said lever will move the chuck lengthwise of the shaft 60.

The sprockets 21, of which one is provided for each chain 16, are adapted to be driven by chains 24 taking over sprockets 25 on a shaft 26 carrying a sprocket 27 driven from a motor 28 by means of a chain 29, or in any other usual or preferred manner, it being understood that the motor 28 and shaft 26 will be supported in any 75 convenient structure as, for example, the substructure of the press. Any suitable or usual control for the motor may be employed to cause it to drive the chain 16 through the instrumentalities just described when it is desired to change 30 the position of the rolls.

The active roll may be supported in any desired position as the web is drawn therefrom to the press, but in accordance with my invention, is adapted to be moved to substantially the position shown in Figs. 2 and 3 of the drawings when it has become nearly exhausted and feed is to be changed to another roll. In this position it will be noted that the new or incoming roll 14 90 has been moved into contact with the web 31 from the expiring roll, which web passes around a part of the periphery of the new roll and then over a guide-roller 32, from which it is led into the press. The motion of said web 31 when the latter is in engagement with'the new roll 14 will set the latter to rotating and in accordance with p the invention the rotation will be continued until the roll has been brought up to the speed of the web which, of course, will be the same as the speed of the press cylinders. As previously stated, it is contemplated that the press will not need to be slowed down appreciably, or at all, for the making of the paster and therefore. the new roll will be rotating at high speed before the paster is made, it being desirable that the new roll and the running web shall be travelling at the same speed when the webs are joined together in order to prevent any slippage.

As shown, a strip of tissue or other thin paper lll 33 is applied over the end or a portion of the end, of the web on the new roll, being pasted or glued to the edge of the web and to the body of the roll to hold said edge tightly against the roll, thereby preventing the air from getting under the web and lifting it from the roll with consequent unwinding, or tearing, as might otherwise occur. As shown particularly in Fig. 4, the edge of the web is cut at an angle to facilitate the tearing of the strip 33, which is much more frangible than the web and is adapted to be readily broken when the paster is made.

For the purpose of applying the paste, or glue, preparatory to making the paster I have shown in Fig. l a movably mounted ductor roller 34 carried in arms 35, pivotally mounted on a rod 36 extending between the frame uprights, said ductor roller being adapted to be held in contact with a fountain roller 37, mounted in liquid adhesive contained in a fountain 38, by means of springs 39 secured at one end to the arms 35 and at the other end to the frame. The fountain 38 is supported from the spaced frames to which it is secured by screws 41. A handle 42 is provided on the rod 36 for turning the same and moving the ductor roller 34 against the tension of the springs 39 from the full line position shown in Fig. 1 to the dotted line position shown in said figure, said roller in the latter position being adapted to contact with the web 31 pressing the same against a backing roller 43 in manner which will be apparent from viewing said Fig. 1. backing roller 43 is mounted on a shaft 44 journaled in the frame and, as will be observed, is-

positioned at an angle as are the

rollers

34 and 37, so that the adhesive will be applied to the running web at an angle corresponding to the angle at which the web on the new roll is cut.

A rocker arm 45 is carried by the rod 36 and is adapted to engage the lower end of a rod 46 mounted in bearings 47 and 48 and carrying at its upper end a roller, or cam-follower 49, adapted to engage a cam 51 carried on one of the chucks 22, which cam is thus adapted to rotate with the roll; said cam has a relatively long dwelling portion and is formed with a depression 52 into which the cam-follower 49 is adapted to fall at a certain point in the rotation of the roll. When said cam-follower is in engagement with the dwelling part of the cam, the ductor roller 34 will be held just out of engagement with the running web 31, and when it falls into the depression 52 said ductor roller will be momentarily pressed against the running web causing the application of adhesive over a restricted area of the latter. The depression in the cam is so related to the end of the web on the new roll and the point of contact of the ductor roller 34 with the running web that the adhesive coated portion of the running web will rst Contact with the leading edge of the web on said new roll causing the two webs to be united, whereupon the tissue paper strip 33 will be torn o and the web of the new roll led into the press.

I have shown in Fig. 3 a modification of the device, a spray being employed in this embodiment instead of the ductor roller 34 for applying the adhesive to the running web. Spray-nozzles 53 are connected with a supply pipe 54 in which liquid adhesive is contained under pressure and valves 55, connecting said supply pipe with said nozzles, are adapted to be actuated by rocker arms 56 carried on rod 36, said arms being adapted to be actuated by operation of the handle 42 and The:

being controlled by the action of the cam 5,1 through the rod 46 and rocker arm 45 in the manner described in connection with the embodiment of the invention shown in Fig. 1. A spring 57 connected at one end to said rocker arm 45 and at the other end to the frame tends to hold said arm in normal position, said arm being actuated together with arms 56 upon operation of the handle 42. It will be understood that the nal actuation of the valve does not occuruntil the cam-follower 49 has ridden into the depression 52 in the manner previously described, thus restricting the area of the web to which the adhesive is applied and properly relating said area to the end of the web on the new roll.

The operation will be apparent from the foregoing description and is demonstrated in Figs. 1 and 3 of the drawings in which the new roll has been brought into position against the running web, in which position it is left until it has been brought up to the speed of the web. The handle 42 is then operated causing the adhesive to be applied to the running web either by means of the ductor roller 34-or the spray nozzles 53 depending upon which embodiment of the invention is employed, and when the adhesive coated portion of the running web comes into contact with the web on the new roll it adheres to the latter tearing ci the strip 33 and leading the new web into the press. The expiring web 105 is then cut, or broken, olf in any suitable or preferred manner and the feed continued from the new roll. When the latter has been exhausted, the operation is repeated to change the feed to the succeeding roll, which, in Fig. 1 is identied 110 by the reference numeral 15.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention, or sacricing all of its material advantages, the construction hereinbefcre described being a preferred embodiment thereof.
