4 Claims.

This invention relates to mechanism for sideregistering the fresh roll of a web roll feeding mechanism for a printing press or the like.

The principal objects of the invention are to provide a simple and practical means for aligning the edge of the fresh web roll with that of the running web prior to splicing; to provide means whereby at the moment the splice is made the new web roll will be in accurate register with the web; to avoid the necessity ofshifting the new roll to one side or the other after splicing and to eliminate the loss of a number of products while the new roll is being registered.

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 elevation of a well known type of reel or frame for'supporting the web rolls, with a preferred embodiment of this invention applied thereto;

This invention applies to roll supporting devices used in newspaper printing presses and the like. The ordinary roll of printing paper is wound on a core which usually is slightly shorter than the full width of the paper. It is a well known fact that the paper rolls come wound on cores in different longitudinal positions, necessitating some means for setting the side register. Heretofore when a new roll has been placed in operation it was necessary to shift this new roll from one side to the other after the splice is made. If the roll is out of register it may cost the loss of a number of products. In all cases products of an inferior nature will be produced. By providing a simple means for side registering the new roll before splicing, these diificulties are avoided and waste of products is practically eliminated, as far as this source of waste is concerned.

The invention is shown as being used in connection with the ordinary construction of pedestals l and 2 carrying a shaft 3 on which is mounted the reel consisting of spiders 4 and 5. This constitutes the frame for supporting the web rolls. As usual a worm wheel 6 is secured to the shaft 3 and rotated by a motor and worm.

a number of rolls.

One of the spiders, as 4, carries the usual movable chuck for loading the paper roll. In this case a handle I is provided secured to a shaft 8 on which is a pinion 9. The rotation of this handle rotates the pinion and moves a longitudinal rack It with which the pinion meshes. This rack is fixed on the chuck ll so as to move the chuck in the direction of the axis of the paper roll. This chuck is provided with a plunger IS in which is rotatably mounted a spindle l2 carrying the cone-shaped end adapted to fit in the hollow core on which the paper roll is mounted. This construction is for the rough adjustment of the spindle toward the roll.

Further and final adjustment of this spindle l2 toward the paper roll is accomplished by a hand wheel l3 which carries an attached collar II. This collar bears against the chuck l l and. the end of this chuck is threadedly attached to the plunger l5. Dog set screws 22 and 23 are provided to fit in longitudinal keyways and prevent further rotation of the chuck plunger l5 and the chuck I l respectively. It will be seen that the rotation of the wheel I3 can be used to push the spindle l2 toward the paper roll when these screws are loose.

On the other side of the reel, a spindle l 6 is rotatably mounted on a shaft I! which is in axial alignment with the roll. This shaft I1 is supported in the spider 5 and so attached as to allow a limited end motion by reason of the fact that the shaft I1 is pressed by a spring [8. It is held in position by a washer IS. A clamping screw 20, operated by a handle 2| secured thereto, operates in a longitudinal keyway inv the shaft I! to preventthe rotation of this shaft but allow longitudinal motion when the clamping screw is unclamped.

A stud 24 is adjustably mounted on the spider 5 and is provided with a small flexible tip 25 of soft rubber or other soft and flexible material. This constitutes a side gauge which is set to reg-' the spindles l2 and I 6. It can be brought up to thispositionon a truck, crane, or any device which is used for supporting it. This roll is y then moved to we left to bring the roll into the position shown in Fig. 4, in which it engages the spindle It at the leftend of the core of the roll and is centered thereby. Next the handle 'I' is operated to bring the spindle l2 into engagement with the other end of the core as shown in Fig. 5. Now the hand wheel I 3 is operated until the end of the roll engages thesoft tip 25 or comes practically into engagementwith it. Of-course, it should not be set up so far as to place any pressure on this soft tip. In this position the screw 20 is set up by its handle 2| so that the spindle i6 is locked against any further longitudinal movement. Also the two screws 22 and 23 are fastened up tight at this time. This procedure, of course, is repeated for each new roll as it is brought into the machine.- By this procedure each roll, before it is pasted, is brought into perfect register and there is no loss of paper due .to failure to register and no imperfect product produced while the roll is being moved over into side register.

An additional feature of the invention is a guide 26 which carries a pointer 21. This guide is slidably mounted on a brace 28 placed across the frame 29 of the printing machine and can be adjusted and secured in adjusted position by a set screw 30'. This pointer is set up to line up with the right hand edge of the web as it is being fed to the press. Then by the mechanism described above the paper roll R may be moved to the left, as shown in Fig. 1 until it registers with the pointer 21. Then the clamping screws 20, 22 and 23 can be used to lock the spindles against any further longitudinal motion.

In Fig. 8 is shown a modification in the form of an adjustable stop 3| mounted on an adjustable guide 32 carried on the spider 5 and regulated in the same way as the flexible tip 25. As the stop 3| is rigid it acts positively against the paper roll and the roll can be brought up against it by the action of the hand wheel l3, as before.

By the arrangements shown and described above, means is provided whereby the turning of the hand wheel l3, by the operator on the right hand end of the roll, will bring the roll into proper position andthe operator will know when it is in proper position by the relation of the edge of the paper to the pointer 21. If the pointer 21 is not used, he will depend entirely upon the roll of paper engaging, or coming practically into engagement-with, the soft tip 25 or the stop 3|.

Thus a very simple means is provided for the proper mounting'and side registering of a new roll so that the latter is pre-registered before it is put into operation and before pasting. This insures perfect side register when the splice is made and the roll begins to be used.

Although I have illustrated and described only two forms of the invention I am aware of thefact that other modifications canbe 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 claim is:

1. In a device of the character described, the combination of a spring-pressed spindle for supporting one end of the web roll, a gauge adjustableinto registration with the same endof the roll for limiting the longitudinal position of the web roll toward said spring-pressed spindle, a

spindle at the other end of the web roll, quickacting means for adjusting said spindle toward the spring-pressed spindle and engaging it in the core of the web roll, and hand-operated means for then adjusting the second spindle toward the first one until the web roll engages said gauge.

2. In a device for supporting web rolls, the combination with the frame of a machine and a reel for supporting the web rolls, of a pointer slidable along the frame and adapted to be fastened in position out of contact with a fresh roll to register with one edge of the running web, said pointer being located adjacent to the end of the fresh web roll supported by the reel, whereby the pointer, set to the edge of the running web from the old roll, will show when the fresh roll is in registration with the running web.

3. The combination with means for supporting a fresh web roll and a running roll, of an adjustable pointer in position to register with one longitudinally adjustable stop member at the other end of the fresh web roll adapted to be 10- I cated in position for the end of the web roll to engage it when moved toward'it from the opposite end, said pointer being located near enough to the end of the web roll so that the operator can see by its alignment with thatend of the web roll when the web roll is moved to a position to register with the running web.

4. The combination with a rotatable reel for supporting the fresh web roll and running web roll for supplying a web to a printing press, of means adjustably supported and adapted to be set to register with the edge of the running web to the press at a distance from the running roll for showing when the end of the new web roll is in proper position and registering the new web roll accurately with the running web before pasting them together.
