5 Claims.
This invention relates to mechanism for splicing a new web roll to a running web without any diminution in the speed of the press and is especially adaptable for the type of roll support used in newspaper printing presses.
The principal objects of the invention are to provide means for covering and protecting the forward. glued end of the web on a fresh web roll while it is being rotated up to Web speed. so that it will not come into contact with the running Web or any surface propelling device or transfer any of the glue thereto; to provide a shield for the above mentioned purpose which will rotate with the fresh roll and in synchronism therewith so as to keep the forward glued end covered; to provide means by which, when the pasting is about to be accomplished, the shield is automatically moved at 'a speed different from that of the surface of the fresh web roll to expose the glued edge for splicing, and to provide means for stopping the shield during the next revolution of the fresh web roll.
Other objects and advantages of the invention will appear hereinafter.
Reference is to be had to the accompanying drawings, in which Fig. 1 is an end view of a well known type of roll supporting reel with a preferred embodiment of this invention applied thereto;
Fig. 2 is an elevation of the same, partly in section;
Fig. 3 is a plan of the shield operating device, partly in section on a horizontal plane;
Fig. 4 is a detail view of the means for rotating the shield, first at roll speed and afterwards at a higher speed, and
Fig. 5 is an enlarged view of the shield as shown in Fig. 3.
The invention is shown as applied to a reel com prising two pedestals Hi and two spiders II which have arms projecting therefrom and which support two or more web rolls at the same time. In this case a running roll A is shown nearly exhausted and a fresh roll B rotating at web speed. The spiders I i are supported on a cross shaft |2 as usual and fixed to the same.
Three gears l5 are shown on the three arms of the reel, one fixed to each of the spindles |6 on which the web rolls are mounted. The fresh roll is rotated at web speed by any known means but preferably by contact with running web W, rotating the gear l5.
On each of the spindles l6 on both sides of the machine are mounted arms These arms are not keyed to the spindles but are adapted to rotate independently thereof and are mounted on the spindles by means of bushings.
Frictionally secured to the hubs of the arms I! on one side of the machine is a gear I8. The gear l5 meshes with a pinion I9 and the gear l8 with a pinion 20. These pinions are rotatably mounted on a parallel shaft 2|. A pair of opposite clutches 22 and 23 are shown having a central member which can be shifted in either direction and in either case will clutch one of the pinions to the shaft 2|. This clutch is operated by a pair of solenoids 24 and 25, either one of which can be energized for shifting the cone clutch one way or the other.
In the normal operation, the cone clutch is shifted to the left so that the gear I5 drives the shaft 2| through gear l9. Through gears and I8 the arms H are driven. On the two arms IT at the opposite ends of the roll is mounted a shield 26. This shield is originally placed, as shown in Fig. 5, over the end of the Web on the roll B, which is supplied with spots of glue or paste ready for the pasting operation. The parts are so timed that in the normal operation this shield will rotate just as fast as the roll and virtually remain in the position relative to the roll shown in Figs. 2 and 5, shielding this adhesive from contact with the tension belts 35 or the web W, which is pressed against the roll B by these belts.
Splined on the spindle I6 is a gear 21 which drives a gear 28. This gear is loose on the shaft 2| and has on it one of the clutch sections cooperating with the'clutch 23. Now when the solenoid 25 is energized this clutch is moved to the right and the gear I8 and arm I! are rotated by the gear 21. The gear 2'! is larger than the gear H5, or at least the gear ratio is such as to drive this arm I! at a higher or lower rate of speed than that with which it has previously been driven so as to move it away from the pasting spots on the roll B and expose the pasted surface for splicing. Preferably it is driven faster than normally.
When the arm I! moves around to the dotted line position in Fig. 1, a solenoid on a small bracket on the spider is energized so as to pull up a stop 3| in the path of a pin 32 on the arm As this arm is frictionally mounted to gear IB it is stopped in this position and does not come around again into contact with the belts or web. Also on the arm I! is a fric- 5) tion surface 33 which engages an end 34 on the lever on the arm on which the stop 3| is mounted to slow down the arm before it reaches the stop and prevent or reduce the shock of the impact. Just after splicing, solenoids 24 and 25 are deenergized to disconnect clutches 22 or 23 and thereby assist in stopping arm H.
The shield extends from one end of the roll to the other. It is provided with adjusting bolts and slots 36 to adjust it to rolls of difierent diameters. In the under side of the shield are spaces 31 for receiving the pasted spots, the other portions of the web being held firmly against the roll by the projecting portions between the spaces.
The method of operating the solenoids is not shown by a wiring diagram or otherwise because it is obvious that the solenoid 24 can be operated by a single push button and anyone well versed in the art could so connect solenoids 25 and 30 as to have them operate in the proper sequence. The manner in which this is done does not constitute a part of this invention.
It will be obvious, of course, that the roll A and the fresh roll on the third pair of arms can be connected up in the same way because it is immaterial in the latter case whether the shield is operated or not and in the case of the roll A the shield will be held against the stop to prevent it from rotating. Of course, the shield has to be placed in the right position before pasting so as to start it correctly.
I have not shown the details of construction mounted on two of the arms of the spider but it will be understood that they are all equipped in the same manner. The shield not only prevents the exposing of the fresh glue but also prevents the forward edge of the paper on the roll B from becoming loose.
It will be seen that this shield furnishes a means for accomplishing these two objects and fully protects the glued edge at all times except when it is time to make the paster.
Although I have illustrated and described only one form of the invention, I am aware of the fact that modifications 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 in this respect, otherwise than as set forth in the claims, but what I do claim is:-
1. In a web splicing device, the combination with means for supporting a fresh web roll, of a pair of arms rotatably supported on the spindles supporting the web roll, positive means for rotating said arms at the same speed as that of the roll, a shield supported at its opposite ends by said arms and adapted to cover the pasted surface of the roll, and means whereby when a paster is to be made the shield can be rotated faster than the roll to expose the pasted surface.
2. In a web pasting device, the combination with a spindle for supporting a web roll, a shaft, two pinions loose on the shaft, a gear fixed on the shaft, a clutch keyed to the shaft and adapted to be moved into two positions, in one of which it fixes the first pinion to the shaft and in the other of which it fixes the second pinion to the shaft, means for driving the shaft from the spindle, and an arm carrying a shield loosely mounted on the spindle and operated by the gear.
3. In a web pasting device, the combination with a spindle for supporting a web roll, a gear fixed to said spindle and rotating with the web roll, a shaft at one side of said spindle, two pinions loose on the shaft, a gear fixed on the shaft, a clutch keyed to the shaft and adapted to be moved into two positions, in one of which it fixes the first pinion to the shaft and in the other of which it fixes the second pinion to the shaft, a second gear, of a size different from the first gear, fixed on the spindle meshing with the last named pinion, a gear loose on the spindle and meshing with the gear on the shaft, and an arm carrying a shield loosely mounted on the spindle and frictionally connected to the last named gear.
4. The combination with a supporting device for a. plurality of web rolls, of an arm adapted to turn on the axis of a web roll, a shield carried by the arm and extending throughout the length of the web roll for covering the pasted edge of the web while it is being brought up to speed, means for moving said shield at a higher speed away from the pasted edge when the paster is to be made, a pin on said arm, a movable stop carried by the supporting device, and a solenoid for moving the movable stop into the path of said pin to stop the arm before it has completed one revolution at a higher rate of speed than the roll.
5. A shield for a web roll, pivotally mounted and arranged to cover a longitudinal surface on the web roll, and having a plurality of recesses on the side next to the roll for receiving the pasted spots on the roll.
