15 Claims. (Cl. 242-58) This invention relates to web printing machines such as are used for printing newspapers, magazines and similar products, and more particularly to improvements in the web supply mechanisms thereof whereby provision is made to indicate at the delivery end of the machine when a web join has been made in order that the products in which a joint is present may be distinguished from the others.

It is the usual practice to apply an indicator in the form of a fiag" upon each full length replacement roll in such a manner that a portion of the flag extends beyond the edge of 'the web at the end of the roll, when the roll is prepared for 16 having its web joined to the web of the expiring web roll. When the completed product is delivered at the delivery end of the machine, the indicating flag, due to the folding of the product, protrudes beyond one edge of the same, and attracts the attention of the operator who may then remove the copies of the product having the joined together web sections therein.

On machines for printing newspapers and like products in which the printing cylinders are arranged to print a web four pages wide, which web is slit in the center to form two separate products having a lengthwise fold, it frequently happens that it is desired to assemble a one page wide sheet into each of the separate products, and

in such instances, it is necessary to feed a narrow web from a half length web roll located in the center of the machine. Both edges of this half roll, when assembled with the other sheets will be adjacent the folds of the completed products, 5 and an indicating flag, if applied to the half roll as above described, would not protrude and be visible to the operator at the delivery of the machine. In order to obviate this disadvantage and to insure indication that a web join has been made in the web of this half roll that products having joined together web sections therein may be identified, it is proposed to apply an indicating means, such as a flag, to the web of an adjacent 'full length roll, when a join is made in 45 the web of the half length roll.

o r'la; 'o,f the objects of this invention is to provide in a printing machine, a web supply mechanism including provision for applying means to indicate the disposition, in a plurality of com- .0' pleted products, of a product having joined together web sections therein.

Another object is to provide means to apply an indicating element to the web of a full length roll of a printing machine, when a join is made in the web of a half length, roll.

Still another object is to provide automatically operable mechanism for applying an indicating element to the web of a web roll when a join is made between a running web and the web of a replacement roll.

A further object is to provide an improved holder for an indicating element or flag, wherein the flag may be firmly held, readily releasable therefrom, and positively applied to a running web whenever a join is made in a running web.

A still further object is to provide a mechanism for applying an indicating element to a'running web in timed relation with the operation of another mechanism of the machine.

It is also an object of this invention to provide a mechanism for indicating web joins, of generally improved construction, whereby the de-.

vice will be simple, durable and inexpensive in construction, as well as convenient, practical, serviceable and efficient in,its use.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts, and in the details of construction hereinafter described and claimed, it being understood that various changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

2 g 2,128,573 i J As generally indicated in Figure 1, a printing machine may be constituted by aplurality of printing units, through each of which a web is run and finally directed to a collecting and folding mechanism from which the completed product is delivered. The product when in the form of a newspaper may consist of a plurality of sections, some of which are printed upon the web from a full length roll, and others from theweb of a half length roll. For the purpose of describing the principles of this invention, it will be assumed, that the webs II and I2 are being furnished from full length rolls l3 of each of the web supply mechanisms l5 and I4 respectively, and that a web I6 is being furnished from a half length'roll ll of aweb supply mechanism l8. The webs l2, II and I5 are run through sets of printing cylinders l9, 2| and 22 respectively, and then over a plurality of guide rollers 23, to any well known form of collecting and folding mechanism, generally indicated at 24, where the printing webs are assembled-and folded with each other, and other printed webs from other units, into completed products and delivered from the machine in the well known manner.

Each of the web supply mechanisms includes aerally at 25, adapted for use with a three roll web supply mechanism to Join the webs, and sever the web of the expiring web roll. The respective webs are mounted upon the roll ,supporting reel 28 which may be rotated, when desired, to position the supported web rolls, into the required operative position. A driven roll rotating belt 21 is provided in association with each roll supply mechanism.

Each of the web joining mechanisms 25 is constituted by a web deflecting member or brush 28 mounted between arms 23 which are pivoted to an extension 3| of a supporting bracket 32, and a web severing device 33 mounted between arms 34, which are also pivoted upon the extension 3|. The

arms

29 and 34 are adapted to be folded up out of the way after a web join is made as shown in connection with the full length roll l3, and to be disposed in web joining position as shown in connection with the half length roll IT. A spring 35 is provided to hold the mechanism 25 in both positions. After being disposed in web joining position the mechanism 25 may be operated to cause the web deflecting member 28 to press the web of the expiring web roll against a previously prepared adhesive covered area on the web of a replacement web roll, for instance, as will bereadilyunderstood from the illustration in Figure 2,

in connection with the half length roll I'I. When the join between the webs is made, the web severing device 33 is operated to sever the expiring web, whereby only the web of the replacement roll is fed into the machine.

A cable 36 is provided having one end secured to an arm 29 and the other end secured to the arm 31 of a manually operable lever 38, whereby downward movement of the lever 38 will tend to urge the member 28 into engagement with web It, to press it against the replacement roll l'l' and join it to the web thereof. In the embodiment illustratcd, the movement of the member 28 by the lever 38 is restrained by a releasable connection 1 between an arm 23, supporting the member 28 and gaging a pin 4| on the arm 23. The catch 38 a solenoid 43 whenever the latter is energized. It will be understood that the arms 34 are limited in their movement toward the replacement roll and that the arms 28 are permitted to move relatively thereto, further toward the replacement roll, when the catch 39 is released.

Provision is herein shown whereby the solenoid 43 may be energized in timed relation with the rotation of the replacement roll l1 and comprises a cam 44 mounted for rotation with the replacement roll and adapted to engage a switch operating arm 45 of a circuit closing switch 48 mounted on the arm of the reel 26 which supports the roll ll". The lever 38, when pressed upon tov move it downwardly, isadapted to operate a circuit-closing switch 41. By the above, described means the solenoid 43 is energized to release the catch 39 by the closing of an electrical circuit from a supply cable 48 through circuit wire 49, switch", cirouit wire 5|, solenoid 43, circuit wire 53, contact I rotatable with reel 25, circuit wire 58, to another supply cable 59. It is to'be understood that the cam 44 will operate switch 45 when the adhesive covered area of the web of the webreplacement roll is in proper position, to operate the catch 39 by closing the circuit between

circuit wires

55 and 55, which latter operation 'is' possible as the switch 41 has been previously moved to circuit closing position by operation of the lever 38.

As above referred to, an indicating element applied directly to the web of a half length roll would, in many instances, be folded into the product and not be visible to the oper'ator'at the delivery end of the machine and, therefore, provision is herein made for applying an indicating element orflagitb the web of a full length roll of a web supply mechanism disposed adjacent to or associated with the web supply mechanism supplying a web from half length rolls. The indicating element applying mechanism herein disclosed comprises an element or flag holding member 6| disposed in position relatively to the'- web l2 of the full length web roll I3, to be adapted to apply a flag upon the same adjacent an edge thereof, as the same passes over a guide roller 62, supported upon the bracket 32.

The flag holding member 6! includes an arm 63 keyed or otherwise secured to one end of a shaft 64 which is journaled in supports 55 fastened to the bracket 32. A wiping leaf 66 preferably made of springy material, such as thin spring steel, is fastened to the top flat surface 51 of the ar'm53 and extends forwardly beyond the end of the same. The leaf 66 lies between upwardly raised shoulders 68 and 83 formed, one along either side of the arm 83, by the formation of a recess ll, concave in cross section transversely of the arm 63. A transversely extending forwardly directed shoulder 12 is' formed by the recess H in the arm 63 under the leaf 66. A lever arm 13 is secured upon the other end of the shaft 64, and has one end of a link 14 pivotally secured thereto.. The other end of the link 14 is pivotally secured to the end of a plunger ii of a solenoid 16 mounted on the bracket 32.

The arrangement of the above parts is such, that energization of the solenoid It will rock the arm 63 to swing the leaf 66 downwardly into engagement with the web I 2, running over the roller 52 to dispose a thin paper-like indicating element or flag 'I'l thereon and by a wiping action, due to its resiliency, cause the same to adhere to the web I2. It will be understood that the indicating element 11 is prepared by having an adhesive 18 disposed thereon, as shown in Figure 5, and is held by the holder 6| by being inserted in the recess H beneath the leaf 66 between it and the arm 63 and being curved thereby between the

shoulders

68 and 69 and overhanging one side of the arm 63 as shown in Figure 6, whereby it will project beyond the edge of the web I2 as shown in dotted lines in Figure 5 when applied thereto. The shoulder 12 limits the extent to which the flag H can be inserted beneath the leaf 66. The resiliency of the material of which the flag TI is madein cooperation with the leaf 66 and the curved form of the flag caused by the

shoulders

68 and 69 and the recess ll firmly holds the flag ll in place in the holder 6|, until it is engaged with the web I! by the leaf B6.

Energization of solenoid 16 may be accomplished in timed relation with the operation of the web joining mechanism 25 by connecting the

terminal wires

52 and 52 of the solenoid I6 to the wires 5i and 53 respectively, whereby both solenoids I6 and 43 will be energized simultane ously under control of the cam 44. From the above, it is obvious that provision has been made by this invention to apply an indicating element or flag to a web substantially simultaneously with the operation of making a web join.

It will be understood that the invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it is therefore desired that the present embodiment be considered in all respects as illustrative and not restrictive, and it will be further understood that each and every novel feature and combination present in or possessed by the mechanism herein disclosed forms a part of the invention included in this application.
