WILLARD, OF NORWALK, OHIO, ASSIGNOR TO THE ROTARY PRINTING 7 COMPANY, OF NOR'WALK, OHIO, A CORBORATIQN OF GHIO APPARATUS FOR MAKING MANIFOLD FORMS Original application filed April 24, 1929, Serial No. 357,744. Divided and this.app1 ication flied" February 24, 1930.

r This invention relates to apparatus which is adapted to be .used in connection with the manufacture of manifold forms, such as those which are intended for use in continuous 5 billing machines. A form suitable for this character comprises a single web, which is fanfolded with interleaved transfer carbon strips, and is then folded transversely in a zigzag manner to form a pack. A manifold form of this character and the method of making the same is illustrated in my copending application, Serial No. 357,744 filed April Qdth, 1929, now. Patent 1,753,764, April 8,

1930 and of which the present application is a divisional application.

The copending application illustrates, describes and claims a method by means of which the manifold forms may be made. Briefly, the method comprises unrolling a web, fanfolding it longitudinally and progressively, inserting transfer strips, transversely perforating the folded web and in-. serted strips, and then zigzag folding them'to form a pack. The carbon strips are taken from rolls, which extend transversely to the direction-of web travel, and are passed over suitable guide bars, which extend into the folds and change the path of travel of the strips to the same direction as the folded form. Frequently, the transfer material is not wound at a uniform angle upon the rolls and hence, the strip will not run true during the unwinding operation. As a result, the edges of the strip will not stay in registration with the edges of the folded forms.

Furthermore, provision must be made for maintaining uniform tension on the roll, for the speed of the roll increases progressively, as it is unwound.

An object of the present invention therefore, is to provide means for compensating for slight variations in the angle at which the roll is wound, without requiring the folding operation to be stopped, and also to maintain uniform tension on the material not- The apparatus for carrying out my invention is illustrated in the drawings, wherein taken on the correspondingly numbered lines a substantial distance therefrom. found that carbon strips can :be interleaved 90 in a satisfactory manner between the web Serial No. 430,591.

Fig. 1 is a diagrammatic View showing a web which is being interleaved with carbon strips in accordance with my invention; :Figs. 2, 3, at and 5 are transverse sections taken on correspondingly numbered lines in Fig. 1; Fig. 6 is aside elevation, partly insection, on an enlarged scale showing the position of the carbon strip atwthe time it is inserted within the folds of the web; Fig. 7 is a perspective view of a manifold pack which is made in'accordance with my method; Fig. 8 is a side elevation showing in detail a satisfactory means for manipulating the carbon roll; and Figs. 9 and 10 arevsections in Fig. 8. y Referring now to Fig. 1, 10 indicates aroll of paper in the form of a web, which is shown in Fig. 2, as a four-part form, having printed forms 11 on one side, and correspondingforms 12 printed on the other side, and spaced alternately in the usual way. Such forms are separated by longitudinal perforations 13, during the printing operation and hence, are presentin thewcb which forms the .roll 10. The web is directed over a guideroll '14 and thence into contact .with the arms 15 which fanfold the web longitudinally along the perforations 13. This operationisknown as the gathering operation and is completed at theguide 16. This guide is shown more in detail in Fig.5, as comprising a box-like structure, having a passageway through which the folded web passes. [The width of the passageway assures asubstantially-complete gathering operation, as the paper passes therethrough. .Anotherboxlike guide 17 is shown beneath theguide 16 andsp-aced I have folds if they are inserted between the guides 16 and 17. The web shown is a four part form and accordingly, three strips of carbon must be used therewith. The rolls for such strips are indicated at 20, asbeing mounted upon vertical axes at the side edges of the folded web.

The transfer strips-indicated at 21'thus ex- 7 rtendfromthe rollsaroundguide rolls 22and 'which is disposed beneath the guide box 17.

then transversely to the path of web travel and into the folds. Deflector or guide bars 23 extend into the respective folds and serve to guide the strips in the same direction as th path of web travel.

After the gathering operation is completed, the folded web, with the interleaved strips, is preferably wound upon a drum 26 A crank 27 may be used for winding the drum at the desired speed. Itis advantageous to wind the gathering forms upon a drum as the tendency for air pockets to form within the folds is greatly eliminated; The web is then taken from the drum and passed through a perforating machine, which perforates the web and carbons transversely, as along the line indicated, for example at 30 in Fig. 2. Thereafter, the forms are transversely folded in a zigzag manner to form a pack, such as that shown at in Fig. 7.

As the transfer stripiis passing over the roll, it is desirable to maintain a uniform degree of tension upon the strip notwithstanding the fact that the size of the roll diminishes, as it is unrolled. To this end, I have shown a'brake shoe 40, which is mounted upon a lever 41, and which is yieldably held by aspring 42 in contact with the drum 43 upon the roll shaft. A suitable adjusting means is provided for varying the tension upon the spring to suit the roll requirements from time to time.

It is also desirable to provide for a slight tilting of the axis of the transfer roll to compensate for variations in the angle at which the roll may be wound. To this end, I have shown in Figs. 8 and 9, a transfer roll, which has a shaft 45. One end of the shaft, as at 46, engages a base 47, while the otherend 48 is suitably journalled in a slide 49. This slide is carried within a second slide 50, which in turn, is movably mounted within a support 51. The slide 49 thus moves in one direction, with reference to the support, while the slide 50 moves in a transverse direction with reference to the same support. Suitable adjusting rods are shown for controlling the position of the slides with reference to the support. It is thus obvious that the axis of the roll may be slightly tilted in any direction in an expeditious manner.

It will be noted that the friction drum 43 is located adjacent the stationary end of the transfer roll axis so that moving the end 48 causes but slight variation in the relation between the drum 43 and the brake shoe 40.

An advantage of the present invention is that a transfer strip may be unwound from V the roll andpassed into the web, and adjusted edges of the web. Furthermore, a uniform tension may be maintained automatically upon the roll notwithstanding the fact that the speed of the roll increases during the unwindmg operation.

I claim:

1. In combination, a support, a roll journalled vertically therein, one end of the axis of the roll being relatively fixed against lateral and axial movement and the other end being relatively movable laterally with reference to the support, a friction drum rigidly mounted on the roll axisadjacent the relatively fixed end thereof, and a shoe mounted on the support and contacting the friction drum, whereby the shoe and drum remain in proper relation when the shiftable end of the roll axis is adjusted.

2. In a device of the character described, the combination with a support, of a roll of transfer material positioned thereon, one end of the roll being relatively fixed against lateral and axial movement, and means for selectively tilting the other end of the roll with reference to the support in any direct-ion at right angles to the axis of the roll.

In combination, a support, a roll of transfer material associate therewith, a pair of slides movable in planes at right angles to the axis of the roll, one slide being movably r 9 mounted on the support, the second slide being enclosed on all but one side by the first slide, said second slide carrying the roll ournal and being movable in a direction normal to the movement of the first slide.

4.. In combination a support, a roll of transfer material associated therewith, a pair of slides movable in planes at right angles to the axis of the roll, one slide being movably mounted on the support, the second slide 211 being enclosed on all but one side by the first slide, said second slide carrying the roll journal and being movable in a direction normal to the movement of the first slide, and a threaded member for each slide, said mem-rilo er having one end rotatably retained in the slide and the other end coacting with a threaded portion in the support for imparting movement to the slide.

ln'testimony whereof, I hereunto affix my signature.
