6 Claims.

This invention relates to an apparatus for making manifold records, and especially to a Web-feeding apparatus for feeding webs of papers to facilitate the making of manifold record forms in which one time carbons employed for making a record on superimposed forms which are assembled and formed into a composite pack. The present invention is a division of my copending application for Letters Patent, filed February 10, 1936, assigned Serial No. 63,282, and entitled Machine and method for making manifold forms.

An object of the present invention is to provide an apparatus for making a manifold pack, which will enable the interleaved record webs to be accurately positioned relative to superimposed webs, so that the various webs may be secured together and severed into individual packs, in such a manner that accurate registration of previously impressed data on one web, relative to previously impressed data on other webs, may be had in the individual packs.

Another object is to provide an apparatus for feeding webs in such a manner that a plurality of webs may be fed, tensioned and superimposed, one on the other, and maintained in accurate registration with each other.

Other objects of the present invention will become more apparent from the following description, reference being had to the drawings, in

which I illustrate a preferred embodiment of my invention. The essential features of the invention will be summarized in the claims.

Referring now to the drawings, Fig. 1 is a side elevation of the machine for making manifold records, embodying my invention; Fig. 2 is a view, illustrating the manner in which the superimposed record and transfer strips are assembled and severed into individual units; Fig. 3 is a side elevation, partially in section of the portion of the machine illustrated in Fig. l, but shown on a larger scale than that illustrated in that of Fig. 1; and Fig. 4 is a sectional detail taken through one of the web feeding drums.

The manifold pack, with which my invention is especially concerned, includes any number of record strips, such as, for example, those illustrated in Fig. 2, at l0, l1, l2 and 13, with interposed transfer strips |4, l5 and Hi. The record and transfer strips are fastened together preferably with an adhesive along one edge and above a perforation line H, while the lower edges of the transfer strips terminate above the bottom edges of the record strip.

This arrangement enables the operator to grasp the tab portion above the perforated line ll, with the thumb and forefinger of one hand and grasp the record strip with the overhanging portion beneath the lowermost edges of the transfer sheet, with the thumb and forefinger of the other hand, and then to snap the two portions apart, thus leaving the detached record strips as a unit in one hand, and the detached transfer strips as a unit in the other hand. The transfer strips are then discarded and the record strips are filed for future use.

To make the pack illustrated at |8 in Fig. 2, I take rolls of record strips on which the desired forms have been previously printed, and I provide a series of openings along a longitudinal edge of the strip. I utilize the openings for receiving projections on feeding rolls to hold the strips in registration during the assembling operation. The record strip rolls are indicated in Figs. 1 and 3, at 30, as being freely movable on individual supports, such as bars 3|.

The bars 3| are illustrated as extending laterally from a frame 32, and correspond in number to the number of record sheets required to form a designated pack. Fig. 2 shows the arrangement on a somewhat larger scale, in which the record strips from each roll are fed between respective rollers 33 and 34, which are powerdriven by an electric motor 35 (Fig. 1). After the strips pass through their feed rollers, they pass upwardly and around respective guide bars 36 and 31, after which they pass over respective drums 40. All of said drums, except that nearest to the motor, carry radially extending pins 4|, that project into the openings 25 which are arranged in a line adjacent the longitudinal edge of each strip and which are in registration with the printed matter on the webs.

A roll 45 bears against the upper side of the strip and has suitable recesses 46 for receiving the pins 4| and coacting therewith to hold the webs against the drums. In the drawings the thickness of the strips is greatly exaggerated hence while it may appear that the pins 4| do not pass entirely through the perforations in the strips and enter the recesses in the rollers 45, they nevertheless do in actual practice. Each roll 45 is journalled at the free end of an arm 41 which is in turn pivoted at 48 on the frame; and the arm is provided with an adjusting member 49, for adjusting the relative position between the roll and the drum. As the record strip passes over its respective guide bar 36, any wrinkles, which may occur, are smoothed out by a brush 15 which bears against the strip and is adjustably carried to vary pressure against the strip. The brush is shown as being carried by a block 18 that is pivotally mounted on a support 11, and this support in turn is carried. by the frame ll.

The transfer strips are arranged to be inserted between the record strips, and to this end, I have shown transferstrip rolls 50 which are journalled on bars I carried by the frame 32. The

web from each transfer roll is extended downwardly in a loop 52 in which a weight 53 is cradled, thence upward around guide bars 54,

55 and 56, from whence it passes between the adjacent record strips and over a drum 40.

The transfer strips and record strips are connected together preferably by adhesive during the assembling operation. This adhesive is applied by a roller 80, journalled in a container 6|, and positioned to contact the underside of the record strip, which passes thereabove, as shown in Figs. 1 and 2.

As the record strips and interposed transfer strips meet the' drum l0 nearest the motor, they pass down an inclined runway 60 along the upper region of which an endless belt 6! is moved. The belt may be provided with pins 62 projecting outwardly therefrom at regular intervals for engagement with the openings 25 of the record sheets, and similarly spaced'pins G3 on the underside thereof, which engage openings 64 in the drum 40 nearest to the motor. The projections on the belt are in alignment with those on the drums l0, wherefore the belt serves to continue the propulsion of the strips and holds them in registration so that they may be sheared into individual uniform packs by a shear mechanism, such as is indicated, for example, in Fig. 1 at Ill.

Before the webs are sheared into individual packs the perforations 25, which are used only to insure proper registration and feeding of the webs, are removed. This may be accomplished as indicated in Fig. 1 by a rotary shear 1i, driven by a motor 12 and mounted on the shear table 13 in any well known manner. This shear severs a strip containing the perforations from the webs as indicated in Fig. 2 at 26.

Each drum 40 is driven from the motor 35 and as shown, this motor is connected by a driving belt or chain 65 with a shaft 66 carried by and extending longitudinally of the frame 32. This shaft is provided, at spaced intervals, with worm gears 6'! which are arranged to engage worm wheels 68 that'are drivingly secured to respective shafts 69 on which the drums 40 are mounted and which are journalled in the frame.

To enable the tension of the upper reach of the record strips to be adjusted, and to allow for a slight adjustment to accommodate any inaccuracy in the spacing of the openings 25, I provide an adjustable connection between each drum 40 and its associated driving shaft 69. This connection comprises an arm which is rigidly mounted on the shaft, as by a clamping screw BI, and which contains a slot 83 for receiving a pin 84 that is fixed to the end wall of the drum. The relative position of the pin within the slot may be varied and locked by adjusting screws 85.

From the foregoing it will be seen that I have provided a simple and efficient web feeding mechanism for use in the manufacturing of manifold record packs from elongated strips or webs, and that the feeding mechanism insures accurate registration of previously printed data on one form with similar or complementary data on another form. Additionally my invention permits the tension of the webs to be adjusted and minor discrepancies in the spacing of gauging perforations in the webs to be compensated for from time to time.
