a corporation of Ohio Application February 26, 1938, Serial No. 192,834 1s claims. (c1. avc- 52)` This invention relates to an improved method and apparatus for making manifold register forms or packs in which carbons are utilized for making a record on superimposed record strips and which carbons are so arranged to be quickly removed from their positionin the pack at the completion of the record. Manifold packs of this character comprise a plurality of record sheets or strips interleaved with transfer sheets to form a single unit.

One form of apparatus 4heretofore developed for making a manifoldpack is illustrated in the copending application of George L. Fulk, Serial No. 99,104, filed September 2, 1936, now patented,

Number 2,144,331, dated Jan. 17, 1939. In such apparatus, the rolls of record paper have been lead upwardly over spaced drums which have been provided with projections that coact with openings along one side of the webs to hold the webs in registration. In view of the fact that the distance between the holes on different strips may vary slightly due to different weights or kinds of paper or to differences in climatic condition at the time the strips are perforated, and in g5 view of the fact that the drums are'spaced apart, considerable diiiiculty has been experienced in maintaining accurate registration of the webs and in rapidly adjusting the mechanism to avoid tearing of the paper.

i An important object of the present invention is to provide an improved method and apparatus for making a manifold pack from substantially continuous Webs of material at comparatively high rates of speed and in such manner thatthe difliculties experienced in maintaining accurate registration of the webs with spaced drums are avoided. In this connection, my invention contemplates a method and apparatus by means of which a machine may run faster than machines heretofore used for this purpose and in which the supply rolls may be conveniently mounted below the interleaving mechanism thus permitting convenient access to such mechanism and to the strips being interleaved.

Heretofore it has been proposed to assemble the strips by means of a single elongated belt. While a single belt is satisfactory where the machine is constructed for a definite number of Webs, it is desirable to construct a machine which i0 is suitable for any number of webs, and in such instances it is advantageous to construct the machine in units which may be added as desired. This, therefore, is another object of the present invention.

An object of .the present invention is to provide an improved interleaving apparatus which will enable the machine to be operated at higher speeds than heretofore and at the same time increasing the'accuracy of registration of the record strips despite irregularities in the spacing 5 of the perforations in the strips.

Other objects and advantages of my invention will become more apparent from the following A specification which refers to a preferred embodiment of the invention illustrated in the accom- 10 panying drawing. The essential novel features of the invention will be summarized in the claims.

In the drawing, Fig. 1 is a partial side view of a machine embodying my invention; Fig. 2 is a fragmentary elevation similar to Fig. 1, but on 15 an enlarged scale, certain parts being broken away to more clearly illustrate the driving mechanism; Fig. 3 is a fragmentary plan view of the mechanism; Fig. 4 is a sectional detail as indicated by the lines 4-4 on Fig. 3; and Fig. 5 2o is a view illustrating the manner of assembling the webs and also illustrating a finished pack.

The manifold pack with which the present machine is used may hold any number of record strips, such for example, as those illustrated in 25 Fig. 5 at IU, II, I2 and I3, with interposed transilfer or carbon strips III, I5 and I6. In the form illustrated, the bottom edges I1 of the transfer `strips terminate short of the bottom edges I8 of the record strips, while the top edges I9 of the 30 transfer strips terminate below the top edge 20 of the record sheets. Ordinarily the record strips may contain a weakening line 2| which is disposed between the top edges of the transfer strips and also beneath a line 22 of adhesive material 35 which connects the record strips to the transfer strips. There is an additional line 23-of adhesive material which connects the record strips together beyond the upper edge of the transfer strips and below the line of perforations 25. 40

The perforations 25 in the/*record strips are used `for maintaining the strips in registration during the assembling operatic/ri, but they are not required in the finished form, so provision is made for severing the narrow strip containing the 45 perforations before the assembled Webs are cut transversely into individual packs. The line of severance of the narrow strip is indicated at 26 in Fig. 5 as appearing above the adhesive line 23.

To make a pack illustrated at the left hand end of Fig. 5 the forms are withdrawn from supply rolls 30, 3| and 32 which are mounted on respective spindles 33 carried by a frame 34. Similarly, the transfer strips are withdrawn from supply rolls 35'and 36 which are mounted on re- 55 spective spindles 31 also mounted on the frame 34. From the various supply rolls the webs ex-` tend upwardly over suitable feeding, guiding and tension regulating devices until they engage respective power driven belts which have projections 4| for engagement with, the openings 25 along one edge of each record strip. The belts thus act to maintain a constant registration of the record strips, one with the other as they pass through the machine.

'I'he adhesive is applied to each record Web immediately preceding its engagement with the belt y4l) of the next web, wherefore any slight relative motion between the webs as may be necessary to maintain accurate registration of them with the belts is not impaired because at the time of engagement of the web with the belt the adhesive has not had sumcient time to set. This adhesive is supplied to the record webs preferably by a roller 42 which engages theunderside of the web lut Prior to the engagement of such web by the succeeding web. The roller 42 is journalled for rotation upon the adhesive container 43, so that the lower portion of the roller is submerged in the fluid adhesive in the container.

At the completion of the assembling operation, the strip containing the perforations 25 is severed from the assembly by a trimmer indicated in general at 44, and thereafter the forms may be cutv into the proper length by any suitable transversely extending cutter.

While I have shown, in Fig. 2, three record web supply rolls andtwo transfer web supply rolls, it is to be understood that I am not limited `to any denite number but that the machine is capable of supplying any number of multiple parts that are capable of being used in writing machines.

In the mechanism shown, an electric motor 45 operates through a power transmission belt 46, power shaft 41, and suitable gearing 48 to actuate feeding rolls 49 and 50 around which the web of record strips is arranged to pass. After leaving the supply roll, each record web vindicated at R passes around the feed rolls, and thence around guides 5| and 52. After passing the guide 52, the web R extends upwardly over a drum 53 and thence horizontally to the next drum 53 across a stationary supporting table 54 carried by the frame 34.

The present invention is especially concerned with the registration of the record strips one with the other as accomplished by the belts 40 heretofore mentioned. Those belts 48 are best illustrated in Figs. 2 and 3. As there shown each belt comprises a continuous looped band of flexible but non-stretchable material. The belts or bands 48 are comparatively narrow being in fact, only wide enough to support the projections 4l and maintain them in an upstanding position when the belt is stretched taut. Each belt' is looped at one end about its respective drum 53 and at its other end is looped around a roll (iii. These belts or bands are positioned adjacent the inner side of the respective drums 53 and their upper reaches pass across and are supported by y the respective tables heretofore described.

the fact ti t the accumuli tion of errors in. the spacing ci.

for auch a. abort distance is nei-ter .t craig to prevent the restoring of the registration 'of the record strips by the projections 4| of the next succeeding belt 40 engaged thereby.

If desired the drums 53,as well as the rollers 50 may be provided with annular peripheral recesses 55 to receive the belts 40 and thus maintain the belts in proper alignment. The tables may also be recessed as at 56 whereby the belts may be set below the surface of the drums and tables, thus causing the drums and tables to form the entire support for the record strips, thereby freeing the belt from all supporting strains. n

Each belt or band 40 is driven in synchronism with the other bands 40. As indicated in Fig. 2, each drum 40 is drivingly secured to a shaft 65 journalled in the frame 34. Each shaft 65 is driven from the drum shaft y41 by the gearing 48 heretofore described. One of the gears of such gearing, namely the gear 86 is drivingly secured to the respective drum shaft 65.

To insure accurate registration, the projections 4I on each belt 40 are spaced the same predetermined distance from the other projection on the same belt, and are spaced a multiple of such distance from the projections of each other belt. To insure the maintenance of the spacings of the projections of one belt relative to the other belts, each drum 53 is provided with radially extending openings 51 which are interengaged by projections 58 on the inner surface of the belts. As the drums are each positively driven from the same power shaft, namely the shaft 41, the interengagement of the projections 58 of the belts with the openings 51 of the drums maintain the desired relationship between the various belts.

To feed the transfer webs, which are indicated at T, I couple the gearing 4B, through drive chains and 8|, `to a shaft 84 on which a roller is rigidly mounted. The shaft 84 may be journalled in arms 86 which are pivotally mounted on a shaft 83, so that the roller 85 which bears against the upper surface of the transfer strip supply roll may move downwardly and progressively as the diameter of the supply roll is diminished.

Each transfer web T passes from its supply roll downwardly and thence upwardly forming a loop 81 in which a weight 90 is positioned to tension the transfer material. From the loop, the transfer web passes over a guide 9|, and thence around guides 92 and 93 from whence it passes into interleaved relationship between the adjacent record webs. however that the transfer webs are guided laterally so as to maintain the relationship of the longitudinal edges to those of the record strips as is indicated in Fig. 5.

By utilizing a series of narrow bands to interengage the openings in the record strips, I maintain registration of the strips throughout the 'length of the machine despite slight irregularities in the spacing of the openings of one strip relative to the spacing of the openings in the other strips. I likewise permit the supply webs to be mounted below the plane of interleaving, thus decreasing the size of the machine and permitting interleaving on a substantially exposed table top whereby the visibility of thc record strips while being interleaved is substantially unrestricted. Likewise, by so arranging the belts that they do not support the record strips as they progress through the machine, I minimize the strains on the beit, I also decrease the strains on the belt by making the belt conmaiau It is tc be understood tively narrow and thus reducing its weight as well as the tendency of .the belt to distort or elongate thereby increasing the speed of the interleaving operation while increasing the accuracy `of registration and safety factor of the mechanism.
