Patented Mar. 7, 1933 UNITED STATES PATENT OFFICE HENRY A. WISE WOOD, OF NEW YORK, N. Y., ASSIGNOR TO WOOD NEWSPAPER MACHINERY CORPORATION, OF NEW YORK, N. Y., A CORPORATION OF VIRGINIA WEB SPLICING APPARATUS Application file'd August 27, 1927, Serial No. 215,933. Renewed May 9, 1932.

This invention relates to a method of splicing a web in a machine for feeding a web to a newspaper printing press or the like and to the apparatus by which this method is carried out.

The principal object of the invention is to provide for first backing up the running web and then moving the new web roll into engagement with the Web opposite the backing up means at the instant of making the paster, thus providing a positive action and controlling the pasting by the rotation of the reel on which the fresh web roll is located. The invention also involves an apparatus for carrying out the method.

Other objects and advantages of the invention will appear hereinafter.

- Reference is to be had to the accompanying drawing, in which Fig. 1 is an end View of a web roll reel and associated parts showing in dotted lines the position the parts assume when the paster is being made; and

Fig. 2 is a fragmentary view of a similar nature showing a modification.

It has been customary, at least in my own previous constructions, to perform the actual act of splicing by moving the running web into contact with the fresh web roll which is tating on a stationary axis at that time. This involves considerable movement of the part that diverts the web from its normal course and in fact an additional movement not necessary. I avoid this extra motion by utilizing the rotation of the reel itself to bring the parts into pasting position. The reel has to rotate anyway and I utilize a small arc of this rotation for this purpose.

Referring now to the drawing, it will be seen that the reel 10 is operated by a motor 11, with a worm 12 in a well known way. This reel has three pairs of arms as shown in the drawing, each pair adapted to carry a web roll. The expiring roll 13 is shown delivering the web W to the press over a guide roller 14. The fresh web roll 15 is shown in full lines in the position which it assumes ust before pasting. It will be understood that this roll 15 is rotated up to web speed by any ordinary means not shown and paste spots 16 applied to it.

The web W is shown as controlled as to its speed by so-called feed belts 17 as usual. Located on this side of the web is a shaft 20 having an arm 21 and a handle 22. On this shaft is a soft surfaced roll 23 which normally is held up inthe dotted line position.

At a time just before splicing, this roll 23 is brought down behind the web so as to back it up. Preferably it is so located as to divert the web slightly out of its normal path, but that diversion of the web, if it occurs, is not for the purpose of performin the paster. It is to be sure that the web ears on the roll 23. This is desired because the path of the web changes with the decrease in diameter of the running roll and it is not exactly in the same place always. The roll .23 is of a suitable soft texture so that it may yield and conform to the irregularities of the roll 15. I

Either automatically, through an electric contact, or otherwise, the motor 11 is started to rotate the reel slowly so as to bring the surface of the fresh web roll 15 up to the full line position. The reel is caused to rotate until the periphery of the new roll is brought in contact with a switch 25, which opens the motor circuit and brings the reel to a temporary halt. The roll 13 is rotated on its own axis by any desired means. The web is now backed up by moving the roll 23 behind it. When the pasted portion 16 on the roll r0- tates to the correct position, the contact 19 is made by the rotation of the roll on its own axis to the proper point. This switch 19, being in the motor circuit, the motor resumes its rotation and quickly moves the 011 from the full line to the dotted line osition.

Thus, when the pasted portion 16 comes around to splicing position at the point where the web touches the roll 23, it will adhere to the web. The butt travels upwardly to the press and the web coming from the butt is severed in any well known manner not shown herein.

In Fig. 2 I have shown a brush 33 connected up and operated in the same way which, as suggested, is a substitute for the roll 23 and 2 i neo aee has even a softer and more yielding surface for the same purpose.

In this way it will be seen that there is no way of projecting the roll 23 or the brush 33 toward the roll except for the purpose of bringing them into and out of operative position. This eliminates one motion or reduces the amplitude of the motion and permits me to form the paster by the travel of the fresh web roll on its reel without increasing that travel and with the added advantage of re-= ducing the complications of the mechanism.

Although I have illustrated and described only two forms of the invention, I am aware 15 of the fact that other 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 these re spects, but what I do claim is 1. In a web splicing device, the combination with means for supporting afresh web roll and the expiring web roll and means for guiding the running web from the expiring roll in a path adjacent to the fresh roll, of a soft roll beyond the web movable into and out of position for engaging the web on the side opposite the fresh web roll, while the web is running from the expiring roll, and means for 39 moving the fresh roll into contact with the web in that position to make the paster.

2. In a web splicing device, the combination with means for supporting a fresh web roll' and the expiring web roll and means for guid-' ing the running web from the expiring roll in a path adjacent to the fresh roll, of yielding means beyond the web movable into and out of position for engaging the web on the side opposite fresh web roll, and means for mov- 40 ing the fresh roll into the contact with the back of the web to force the Web against the yielding means to make the paster.

In testimony whereof I have hereunto affixed my signature. HENRY A. WISE WOOD.
