The principal object of this invention is to provide a pasting device for splicing newspaper printing machine webs which is intermediate be tween the two types of pasters that have been 5 produced heretofore.

It is designed to avoid the necessity of stopping the press during the pasting but at the same time to contain simpler mechanism than is necessary when the web is spliced at full web speed. 10 The invention involves the imparting to the incoming roll of rotation by force applied to it other than through the running web itself and giving the incoming roll a start to relieve some of the strain on the web at the time of pasting.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings, in which Fig. l is an end view of a reel for supporting 20 a plurality of web rolls with a form of splicing device applied thereto and having means for starting up the new roll at the time of the pasting operation;

Fig. 2 is a front elevation thereof; Fig. 3 is a view similar to Fig. 1 showing the final act of performing the pasting operation, namely the separation of the web;

Fig. 4 is a view similar to Fig. 1 showing a modification;

Figs. 5 and 6 are sectional views showing a connecting element which is used in this form of the device;

Fig. '7 is a view similar to Fig. l and Fig. 4 showing another modified form, and

Fig. 8 is a front view of the same. It has long been the practice in the newspaper printing industry to splice paper rolls without stopping the press. In general this has been done in connection with a rotatable reel carrying a plu- 40 rality of web rolls. This splicing, however, has been done at the threading speed, which is very slow. Since the decelerating and accelerating of the press for the making of a slow speed paster absorbs considerable time, automatic machines 45 have been developed for making these splices with the web running at the full speed of the press. Such a machine naturally is more or less complicated.

This invention is designed to fill the gap be- 50 tween the very slow speed paster and the entirely automatic paster. The purpose of the invention is to increase the productiveness of the press by avoiding the slowing down to threading speed while still retaining a simple device for the past- 55 ing operation. Very often with the slow speed pasters, only the strength of the paper is used in bringing the incoming roll up to the desired speed. According to the present invention the force of rotation is applied to theincoming roll by external means instead of through the web.

The invention can be carried out in many forms. It can be operated by the lowering of the web pressing member to speed up the incoming roll through power furnished by the operator or it can be speeded up from the drive of the press proper or from the rotation of the reel, or in other ways.

In Figs. 1, 2 and 3 is shown an example of the first-of the above mentioned ways of operating. The invention is shown as applied to a reel made up of spiders 3 carried on a central shaft I on supporting members 2. In this case three web rolls can be supported on the reel. The web is fed from the butt 4 of the exhausting roll to the printing press in the conventional manner over a guide roll. The incoming web roll 5 is brought to the position shown with the pasted end 6 in approximately the position shown.

A brush frame I is shown pivoted above on brackets 8 carried by the frame of the press. It is normally held back in inoperative position, as shown in full lines in Fig. 1. Pivoted to this frame is a rack arm I carrying rack teeth II. It is pivotally hung from above by a link l3 having a slot and stud arrangement l2 by which it is connected with the press frame to prevent the lowering of the rack below a certain level. It permits a limited up and down motion of the rack about its pivot on the frame 1.

This frame carries the usual brush lever l4 pivotally mounted thereon and normally forced downwardly by springs l5. A brush or brushes l6 are mounted on the lever M at one end and it has a severing knife [1.

When the splice is about to be made the operator grasps the handle l8 of the brush frame and moves the brush frame 1 from the full line to operative or dotted line position shown in Fig. 1. This brings the brushes into contact with the running web W and ready to force that web out of its line of travel into contact with the roll 5. However, before this occurs the movement of the rack arm it! caused by the swinging of the frame I will cause the teeth I I to rotate a pinion 19 which is fixed to the stud of the incoming roll and start that roll rotating on its axis. Thus by the operation of the brush frame into operative position the new roll is rotated at a speed considerably higher than that of threading and the Web is pressed against the new roll to form a paster when the pasted end 6 comes around into contact with it.

It 'will be seen that the speeding up of the incoming roll is an operation that is performed by hand and is performed by the action of pressing the web against that roll. The pasting operation is assisted materially by the rotation imparted to the new roll by the rack and pinion. This removes much of the strain on the incoming roll when the paster is made and permits the making of successful pastel-s at speeds materially higher than the threading speed.

In Figs. 4, 5 and 6 another way of carrying out the invention is shown. The reel is shown rotated by a worm as usual and the brush arm is shown with the parts previously described. A segment gear 20 is pivotally mounted on a shaft 35 supported by brackets 2| secured to the frame of the press. A cam lever 36 is also pivotally mounted on the shaft 35 and has one end pivotally connected with the press by an arm 31. On the press are connections in the form of a crank or otherwise so that when the press is running a link 3! reciprocates and oscillates the cam lever 35 continuously. The cam lever 36 normally oscillates idly, but is connected detachably with the segment arm 20 by a spring-pressed engaging pin 38 mounted in a recess in the segment arm 20 and penetrating a slot in one end of a link 39. The other end of this link is pivotally secured to the brush arm I and moves with it. It is provided with a collar 49 for operation by an inclined cam surface 4| on the link 39. The collar 40 is located on the end of a rod which carries the pin 38. In the position shown in Fig. 5 this pin is pulled out while in the position shown in Fig. 6, the spring behind it pushes it in.

By means of a push rod 42, collar 43, spring 44, washer 45, lock nuts 46 and a bracket 47, secured to the press frame, the segment arm 20 is springpressed in either of its extreme positions. The segmental row of teeth 22 on the gear 20 are provided for cooperation with the pinion I9 secured to the spindle of the incoming roll, as in the other form described, for giving this roll 5 a start at the time of splicing.

When the brush arm 1 is moved inwardly by hand from the full line position in Fig. 4 to the dotted line position, the link 39 is moved inwardly from the position shown in Fig. 5 to that shown in Fig. 6. This releases the pin 38 and it comes into a plane in which it will engage the edge of the lever 36. As that cam lever is being oscillated the segment arm 20 is given a rapid oscillation from the full line to the dotted line position in Fig. 4 and rotates the roll 5. This automatically disconnects the pin 38 from the cam lever 36 at the end of the stroke and the action is not again repeated until the brush arm 1 is raised to the inoperative position and lowered again as thus described. It may be raised at any time after the roll 5 is brought around to the running position.

It will be seen that this mechanism is operated in a manner similar to that described in connection with the first three figures of the drawings because assistance is given to the web in bringing the new roll up to speed and this is initiated by hand operation. As in the other case the application of further pressure on the brush I 6 compresses the springs l5 and permits the knife I! to sever the web. In this case the motion of the starting up of the roll is initiated as before by the movement of the brush frame down to pasting position but the actual power for rotating it is imparted from the press through the lever 31.

In the form shown in Figs. 7 and 8 the rotation of the reel itself is used to start the incoming roll into rotation. Many of the parts shown on this sheet are the same as described above and will not be described over again. In this case a rack arm 23 is pivoted on a bracket 24 carried by the press column 25. This rack arm 23 carries teeth 23 for cooperating with the pinion l9 which is in the same relation to the other parts as described above. In this case, however, just prior to splicing, the spindle of the incoming roll 5 is in the dotted line position in Fig. '7. By lowering the brush frame I to the full line position shown in these figures by hand as before, a chain 26, connected with the hub of the frame i, is operated. This chain passes over a sheave 2'! connected with a bell crank 28. This bell crank is provided with a link 29 pivoted thereto and pivoted to the rack arm 23. Therefore, the lowering of the frame I to operative position also lowers the rack 23 At the moment that the brush I 5 contacts with the web W an electric contact 30 carried by the brush arm touches a contact 31 mounted on the bracket 8. This closing of the. open circuit in which these contacts are located starts the motor 32 which is also in this circuit. This motor, through a worm 33 and worm wheel 34, which is secured to the shaft I of the reel in the usual way, rotates the reel. This rotation of the roll 5 bodily from the dotted line to the full line position in Fig. '7 with the rack in engagement with the pinion gives the incoming roll 5 a start in the direction indicated by the arrow. This, as in the other cases, removes the strain from the web W as the brush l6 presses this web against the incoming roll. In this case, instead of rotating the roll directly by the movement of the brush frame or by the power of the press, the power for rotating the roll is provided by the rotation of the reel caused by the motor. In this case the web is severed as in the other cases.

It will be seen that in all these cases the movement of the brush frame toward pasting position at least initiates the rotation of the fresh roll on its own axis to relieve the strain on the running web when it is united with this roll. In

the first case the movement of the frame not only initiates but completes the action of rotating the new roll. In the second case the power for rotating this roll is imparted by the press and in the third case by the reel. In all cases the incoming roll is started into rotation by force applied to it by other means than the running web itself and that means is very simple. Furthermore this invention provides a practical means for speeding up the pasting operation from the slow speed mechanism heretofore provided for that purpose, without the necessity of all the complication of the automatic mechanism required in automatically pasting at full web speed. This invention fills the gap between these two extremes and permits the medium sized plants to perform a paster without much loss of time and without burdening them with excessive expense.
