maamm 2, 1m, Bu-lalNo. 506.236 mm. (cam-5a) This invention relates to the splicing of a roll of paper to a running web, and is particularly applicable to the replenishing of the web of a news-.
paper printing'press. The invention is applicable 6 to a device of the above mentioned type in which the splice is made while the web is running at full speed.
The principal object of the invention is to provide a convenient means by which the glue or ad- 10 hesive is carried by the fresh roll'but in an inactive condition to enable the roll to be brought up to web speed before the adhesive is brought into an active condition, and then to provide means for bringing the glue into play so as to cffeet the splicing.
Other objects and advantages of the invention will appear hereinafter.
Reference is to be had to the accompanying drawings, in'which v Fig. 1 is a side view of a web splicing device showing the preferred embodiment of this invention;
Fig. 2 is an elevation of the same;
Fig. 3 is a view similar to Fig. 1, showing a modi- 25 fl'cation, and
Fig. 4 is an elevation of the modification shown in Fig. 3. i
This invention relates to the act of splicing a rotating roll to a running web,and is concerned with the form in which the adhesive is employed,
and the way in which the adhesive is applied so as to splice together these two elements.
In accordance with this invention the adhesive in one way or another is left inactive until the 35 last rotation of the new roll before splicing is about to take place. Then the adhesive is rendered active so that the next time it comes around to registration with the running web it will unite that to the web on the roll. Means also is prom vided in accordance with some of the forms shown for actively forcing the adhesive from a protective covering on the surface of the roll to effect the splice.
In the form shownin Figs. 1 and 2, the fresh 45 web roll in is shown as mounted in any ordinary way and as movable toward the running web II for the completion of the splice. 0n the roll I0 is provided the adhesive l2 in the form of a spot or a plurality of spots of material thickness and 50 containing an excess of adhesive in a soft state, each covered by a protecting shield l3 of frangible v paper. These shields l3 are shown as of angular formation, that is, they do not extend parallel with the axis of the roll, but either extend in one 55 position at an angle to the axis, or have their opposite ends slanting at opposite angles to the axis for the purpose of 'easiefflrupture of the shield when the time comes'for-Ithe splicing.v
This form of the inventionis shown as. provided with runningbelts l4 operated from a shaft 5 l5 which is operated by the pressand in-propor-- tion to web speed, so that these belts l 4 move practically at the same rate of speed as the web II. The spots of adhesive l2 are spaced apart at intervals along the roll from one end to the other, 10 and the belts. are located at points between these spots.
The operation is as follows:
When the running roll 16 gets quite small the tapes ll, of course, are running against the surl5 face in the usual way. Now the incoming roll I0 is moved over into contact with the web which is in contact with the belts I with the web between them and the roll. This position of the parts is kept up until the roll I0 is running at web 20 speed. When it is judged by the operator that it is time to make the splice, the roll In is moved harder up against the belts I, so much so that they yield and allow the roll Ill to come against squeezing rolls I! carried, by the frame l8 on which the belts are carried. These rolls H are located in the path of the spots l2 and their shields l3. Therefore the first time these shields come against the roll I! the pressure of the rolls will disrupt the shields and force the adhesive material out on the surface of the roll l0 where, of course, it will also come into contact with the running web II. This is as much of the splicing operation as need be described because this invention does not relate to the other features, such as severing of the web, etc.
In the form of the invention shown in Figs.
3 and 4, everything is the same as shown in Figs. 1 and 2, except that the squeeze rolls 20, which take the place of the rolls H, are mounted on arms carried by shafts 2|, each shaft having a handle 22. Spring-pressedrods 23 normally tend to force the nails 20 outwardly into splicing position to have the same efiecton the spots of adhesive I2 as in the other case. A latch 24 is 5 provided for each one of the shafts 2| and holds them back against the resistance of the springs on the rods 23 until the operator releases the latches. The latches are all connected by a rod 25 to allow them to be released simultaneously. 5
In each of these casesthe invention is shown as applied to an ordinary reel 40 which carries Although I have illustrated and described only two forms of the invention, I am aware of the fact that other changes can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims. Therefore I do not wish to be limited to any of the forms shown, but what I do claim is:-
1. The method of splicing a runningweb to a rotating web roll, which consists in providing the web roll with adhesive having a temporary covering over it and, at a time just before the splice is to be made, displacing said covering to enable the adhesive to spread on the surface of the roll to unite the surface of the web roll to therunning web.
2. In a mechanism for splicing a running web to a rotating web roll, the combination of an area of adhesive material, means on the roll for keeping the said adhesive material from acting on the running web until it is desired to make the splice, and means for then disrupting said means on the roll to expose the adhesive material on the surface of the running mil so that it may join the said surface to the running web.
3. In an apparatus for splicing a running webto a rotating web roll, the combination of a shield applied to the surface of the rotating roll and having under it a supply' of adhesive, whereby the adhesive is kept in an inactive condition, and means for applying pressure to the shield to squeeze the adhesive from beneath it on the surface of the roll, whereby the said adhesive will be in condition to cause the roll and web to adhere when they come into contact.
4. The combination, in a device for splicing a running web to a rotating roll, of an area of adhesive on the surface of the roll, a temporary shield for protecting the adhesive from coming 40 into contact with the web, and means whereby the movement of the rotating roll bodily toward the running web will cause the adhesive to be the roll in an exposed condition for the purposedescribed.
6. In a web splicing device, the combination of a support for movably mounting a web roll, running belts for acting on the running web at substantially the speed of the web, and also for rotating the web roll when it moves up into contact with the web, spots of adhesive on the surface of the web roll out of registration with said belts, and rollers carried in such position that when the rotating web roll moves up to a certain point, said rollers located in the paths of said spots will spread the adhesive on the surface of the web roll'in a position to engage the surface of the running web.
7. In a web splicing device, the combination of a support for movably mounting a web roll, running belts for acting on the running web at substantially the speed of the web, and also for rotating the web roll when it moves up into contact with the web, spots of adhesive on the surface of the web roll out of registration with said belts, a frame carrying the running belts, a shaft on said frame, arms carried by the shaft, rollers mounted on said arms, yielding means for forcing the arms forward into active position, a latch for holding them back so that the rollers will be inactive, and means for releasing the latch to allow the spring to operate the rollers.
