MACHINE FOR PERFORMING PRINTING, PERFORATING, AND OTHER OPERATIONS ON STRIP MATERIAL 'Applieation filed November 3, 1927. Serial No. 230,732.

This invention relates to a machine for performing printing, perforating and other operations on strip material and is designed particularly for use in the manufacture of printed manifold forms.

In the manufacture of manifold forms, the forms are ordinarily printed in transverse rows upon a wide sheet of paper in a cylinder press and the sheet is then folded along longitudinal lines to superimpose the sheets of each form one upon another. The folded strip must then be either perforated transversely or cut apart between forms and in most cases the individual forms must have holes punched through them for filing purposes. Also in some instances, the edges of the folded strip must be trimmed to free the sheets of the forms from each other.

Different printed matter specified by the particular concern for whom the forms are made is required for each job and this makes it necessary to remove the printing cylinders from the press and replace them with another set of cylinders for each job. Standard forms in many instances differ only in the printed matter upon the top sheet of the form and it will be apparent that if a special machine were to be provided which is capable of properly printing the distinctive matter upon the top leaf of the folded strip considerable saving could be effected by employing the large cylinder press or printing only the matter common to a number of different forms and subsequently printing the distinctive subject matter upon the top leaf of the folded strip, thus avoiding frequent changing of the cylinders of the large press and enabling a reserve supply of printed and folded forms to be carriedin stock. There are, however, a number of serious difficulties to be overcome in such a subsequent printing operation and in so far as I am aware, the large cylinder press has always prior to the present invention been used to print the entire subject matter on the forms and it has consequently been necessary to provide a new set-up on the large press for each job.

The present invention has for its object to provide a simple and relatively inexpensive machine which is capable of rapidly performing any or all of the above mentioned finishing operations upon a folded strip of forms.

In perforating, cutting or printing the folded strip subsequently to the original printing and folding operations, it is essential that the proper spacing be maintained and the performance of these operations in a continuously operating machine is made exceedingly difficult by shrinkage of the paper and by reason of the impossibility of maintaining perfectly uniform spacing in the original printing on the strip throughout the length of a large roll of paper.

One of the main objects of the present invention is to provide a manuall controlled power operated feed device or the combined machine of the present invention by which the operations performed on the strip may be at all times maintained in proper spaced relation with respect to the original printed matter on the strip regardless of lack of uniformity in the spacing of this printed matter due to shrinkage of the paper, lack of uniformity in the original printing and other causes.

A further object is to provide a strip feeding means by which the portions of the folded strip acted upon in the machine are maintained flat upon the bed of the machine and taut during each operation performed upon the strip.

A further object is to provide a machine which can be quickly adjusted to perform any or all of the above mentioned finishing operations during the passage of a foldtions thereof as will be apparent to one are slidably mounted in the frame.

skilled in the art to which the invention appertains.

Reference should be had to the accompanying drawings forming a part of this specification, in which:

Fig. 1 is a perspective view looking downwardly toward a front corner of the machine;

Fig. 2 is a side elevation of the machine;

Fig. 3 is a top plan View of the machine with the perforator and printing heads omitted;

Fig. 4 is a transverse section taken on the line indicated at 44 in Fig. 3;

Fig. 5 is a fragmentary detail View showing the strip feeder slide in side elevation;

Fig. 6 is a sectional detail view showing one of the punches;

Fig. 7 is a transverse section through the perforating head; and

ig. 8 is a transverse section taken on the line 8-8 of Fig. 3.

Referring to the accompanying drawings, the machine is supported with an elongated supporting frame 1, provided with supporting legs 2 and a bed 3 extending the full length thereof. At the rear end of the frame there is mounted directly over the bed a vertically movable head 4 which is supported on vertical guide rods 5which One or more transverse cross bars 6 are mounted upon the under side of the head 4 and these bars carry serrated perforating plates 7 which coact with stationary dies ts mounted upon the bed of the machine. The perforating plates 7 serve to form transverse lines of perforations across the strip between successive forms and in order that the lines of perforations may be properly spaced and to adapt the machine for different lengths of forms, the cross bars 6 are adjustably mounted in ways 9 formed on the underside of the head 4 so that they may be adjusted to the desired position beneath the head. Beneath the forward portion of the head 4 a cross bar 10 is rigidly secured to the frame and extends across the bed, the bar 10 being provided centrally thereof with a notch 11 on its under side through which the folded'strip is guided. The bar 10 is provided with a series of vertical apertures 12 each adapted to receive a punch 13 which projects above the top of the bar and is normally held in its uppermost gosition clear of the strip by a spring 13. ecured to the bed beneath the bar 10 is a stationary die 14 with which the punch or punches carried by the bar 10 cooperate the strip being fed between the

bars

10 and 14 and the punches bein operated by the head 4 upon its downwar movement. The head 4 is reciprocated during the operation of the machine by means of connecting rods 15 which are pivotally connected at their.

upper ends to the vertical guide rods 5 which support the head and which are mounted at their lower ends upon an eccentric 16 which are fixed to transverse shafts 17 and 18. The folded strip of forms is intermittently fed through the machine as will be hereinafter explained in detail and during the intervals between the movements of the strip, the head 4 moves downwardly to form the transverse perforated lines and to operate the punches 13 to punch the holes in the forms.

Immediately in advance of the head 4 there is mounted a printing head 19 which also moves up and down away from and toward the bed 3. The head 19 is carried by rearwardly extending arms 20 which are pivoted at 21 to the rear end of the frame and the head 19 carries a platen 22 which is adapted to carry the printing plates, the bed being provided beneath the platen 22 with a bed plate 23 upon which the strip rests during the printing operation. The head 19 is constantly'reciprocated during the operation of the machine by means of connecting rods 24 pivoted at their upper ends to the arms 20 and at their lower ends to levers 25 which are pivoted upon a transverse shaft 26, the levers 25 being actuated by links 27 connecting the same to eccentrics 28 carried by a cross shaft 29. The head 19 carries inking rollers 30 which are supported by rods 31 extending upwardly on opposite sides of the head and yieldingly pressed against the platen '22 by means of springs 31 acting on the rods 31. The rods 31 are carried by a rock shaft 33 journaled in the upper ends of brackets 34 attached to the head 19. Fixed to the rock shaft 33 at one side of the frame there is a forwardly extendin arm 35 which is connected by a link 37 to the upper end of a post 38 fixed to the side of the frame 1 so that the movement of the head causes the rollers 30 to travel over the face of the platen 22 to apply ink to the plates on the platen. 4

The head 19 is provided with an upwardly extending forwardly inclined extension 39 upon which is mounted an inking disk 40 which receives ink from a suitable inking receptacle 42 carried by the extension 39 at the upper end thereof. The swinging movement of the aims 32 during the upward and downward movement of the head 19 is such as to cause the rollers 30 to move from the position shown in Fig. 2 across the face of the platen 22 and upwardly over the face of the disk 40 during the downward movement of the head and to move back over the disk 40 and the face of the platen 22 to the position shown in Fig. 2 during the upward movement of the head. The disk 40 is provided on s rear face with ratchet teeth 43 which are engaged by a pawl level,

44 which is actuated by s ring 45 in a direction to impart a turning movement to the disk. The arm 44 is engaged during the movement of the head 19 by an arm 46 on the rock shaft 33, the movement of the arm 46 being such that upon the downward movement of the head 19, the arm 46 moves away from the arm 44 and permits the spring 45 to actuate the lever 44 in a direction to turn the disk 40. During the upward movement of the head, the arm 46 is rocked toward the lever 44 and moves the lever in opposition to the spring 45 to shift the pawl end of the lever into engagement with another ratchet tooth on the disk 40. The disk 40 is thus intermittently turned during the operation of the printing head. The ink receptacle 42 is provided with the usual ink feed roller to which is attached a ratchet 47 which is engaged by a pawl 48 pivoted at 49 and having an extending arm 50 which is connected by. a connecting rod 51 to the link 37 so that during each reciprocation of the head, the ratchet 47 is advanced one tooth. The link 37 is preferably provided with a series of spaced holes 52 so that the connection between the'link 37 and the connecting rod 51 may be adjusted to obtain the proper amount of movement for the actuating pawl 48.

The operation of the printing head 19 is substantially simultaneous with that of the head 4 so that the printing as well as the punching and perforating is performed dur ing the intervals in which the folded strip is at rest. A reciprocating feed device is provided for imparting the proper amount of longitudinal movement to the strip in the intervals between the perforating, punching and printing operations and this feed mechanism will now be described. 6

The frame 1 is provided along opposite sides thereof with guide ways 53 in which is mounted a transverse slide 54 which has fixed thereto a lower clamping bar 55 which extends across the bed and slides beneath the folded strip. The bar 55 carries vertical pins 56 which project upwardly therefrom and slidably mounted on these pins is an upper clamping bar 57 which-is pressed downwardly toward the bar 55 'by springs 58 carried by the pins 56. The upper clamping bar 57 rests at its opposite end upon longitudinally extending bars 59 which are slidably mounted upon vertical pins 60 fixed to the side members of the frame and projecting upwardly therefrom,'the bars 59 being pressed downwardly by springs 61 carried by the, pins 60. The bars 59 are provided at their frontand rear ends with rollers 62 and 63, the rollers 62 resting upon cams 64 carried by a transverse shaft'65 and the rollers 63 being supported upon cams 67 carried by a transverse shaft 68. The

cams

64 and 67 each have two semi-circular portions of different diameters and are rotated inunison so that during onehalf of the revolution, the rollers 62 and 63 are resting upon the smaller portions of the cam and during the remainder of the revolution upon the larger portions of the cams. When the rollers 62 and 63 are resting upon the larger portions of the cams, the bars 59 are raised and the clamping bar 57 is held against the pressure of the spring 58 out of contact with the strip. The

cams

64 and 67 are driven at a speed such that during the forward stroke of the slide 54, the bars 59 are in their lowermost position and the.

clamping bar 57 is heldagainst the paper strip clamping the same upon the bar so that during the forward stroke of the slide, the strip is pulled forward. When the slide reaches its forward limit of travel, the rollers 62 and 63 ride up onto the larger portions of the cams lifting the bars'59 and clamping bar 57 to release the strip while the slide is-on its return stroke.

The slide 54 is actuated by means of connecting rods 69 extending from the slide rearwardly along opposite sides of the frame and connected at their rear ends to cranks 71 which are mounted for radial adjustment upon a transverse shaft 72. The connecting rods 69 are. made in sections connected by a telescopic joint 70, the radial adjustment of the cranks 71 together with the telescopic adjustment of the connecting rods 69 enables the stroke of the slide to, be adjusted to any desired length, as is desirable to adapt the machineto operate upon strips in which the forms are of. different lengths. The connecting rods 69-are connected to the slide 54 by means of pivots 73 which are carried by blocks 74 slidably mounted in notches 75 in the slide 54 at opposite ends thereof. amount of play between the connecting rods and the slide and these blocks are normally held against the rear ends of the notches 75 by means of compression coil springs 76 so that the movement of the slide normally corresponds to the stroke of the connecting rod. Adjacent the forward limit of move- .ment of the slide there is mounted a cross shaft 77 which extends between the side 1 members of the frames immediately above the bed 3. This cross shaft has 'a pair of cams 78 thereon adjacent the ends thereof which lie in the path of movement of the I slide. At one end the shaft 77 has attached theretoa hand lever 79 by means ofwhich the operator may adjust the positions of the cams, The cams 78 areso positioned that by turning the lever 79, they may be moved to a position overlapping the stroke of the slide so that the slide will engage with thecams and be stopped slightly short of its normal forward" limit of movement, the springs 76 permitting the slide to stop and the connecting rod The notches 75 permit a slight 25 ward direction by springs 85. The arms 83 to move through its normal cycle. By adjusting the cams 78, small adjustments may be made in the stroke of the feeder slide to vary the extent of movement of the strip and compensate for slight variations in the spacing of the printed matter on the forms. A pointer 80 is rigidly attached to the frame he can move the lever 79 forwardly or rearwardly to lengthen or shorten the'stroke and maintain proper registration of the "forms with the perforating, punching and printing devices.

Immediatelyto the front of the cross shaft 77, there is mounted a holding clamp which comprises a lower bar 81 'fixed to the bed of the machine and a movable upper bar 82 carried by arms 83 pivoted -on a cross shaft 84 and normally pressed in a downcarry rollers 86 which travel on cams 87 .fixed to the cross shaft 65. The cams 87 are identical with the cams 64 except that they are oppositely positioned so that the arms 83 are lowered as the bars at 59 are raised causing the strip to, be gripped between the 'bars 81 and 82 and held against movement while the slide 54 is being returned to its rearmost position and while the printing, punching and perforating operations are being performed. v

The entire mechanism of the machine is operated by an electric motor 88v mounted beneath'the forward portion of the frame and having'a shaft 89 which drives'a belt 90 extending over a pulley 91 carried by a. transverse shaft 92 rearward'ly-of the motor. The shaft 92 is locatedmidway between'the shafts 29 and 17 and. has a pair of small gears 93 thereon one .of which meshes with a large gear 94 on the shaft 17 and the other of which meshes with a large gear 95 on the shaft 29. The gear 94 meshes with a gear 96 of the same size on the shaft 18, so that 'the eccentrics 16 are driven at the same speed, and thegear 96 with a gear 97 on the crankshaft 72, which operates the feeder slide. The shaft 72 has a sprocket 98 thereon whichdrives a sprocket chain 99 which runs over a sprocket 100 on the cam shaft 68. The cam shaft 68 has a second Sprocket 101 which drives a s rocket chain 102 which extends over a sproc et 103 on the cam shaft 68, the sprockets 101 and 103 being of the same size so that the two

cam shafts

65 and 65 are driven in the same direction and at the same speed. The

shafts

17, 18, 29, 72, 65 and 68 are all driven at the same speed and the eccentrics carried by the shafts upper shaft 104 has keyed thereto a pulley- 107 upon which is loosely and rotatably mounted a ring 108 of friction. material such as rubber. tively driven while the friction ring 108 is free to turn with respect to the pulley 107 and is driven by frictional engagement with the strip. The shaft 65 carries a sprocket 109 which drives a sprocket chain 110 which passes over a sprocket-111 fixed to the shaft 104. The shaft 104 has fixed thereto a gear 112 which meshes'with the gear 113 on the shaft 105 so that the shafts 104 .and 105 are driven in opposite directions, the shaft 105 being driven in a direction to feed the strip forwardly. jThe smooth roller 106 maintains a tension on the strip to keep the strip taut and prevent any buckling of the strip in the machine but does not have sufficient frictional engagement with the paper to prevent its slipping freely when the strip The lower roller 106 is posiring 108 exerts a slight pressure upon the strip by its weight so that the smooth roller 106 can exert the necessary pull upon the strip while it is released from the holding clamp. I It is sometimes desirable to trim the longitudinal' 'edges of the folded strip 'to sever ,the superimposed leaves of the forms from each other and this is accomplished by means of rotating trimmer knives 114 keyed to the

shafts

104 and 105. These knives may be adjustedto the proper osition with respect to the strip and are eld-in adjusted positions by means of set screws 115. When the knives 114 are inoperation, they engage with the periphery of the feed roller 106 and act to trim off the edges of the strip.

At the discharge end of the machine there is mounted a vertically reciprocable shear blade 116 which slides in vertical standards 117 fixed to the forward end of the frame. The opposite ends of the shear blade 116 are attached to connecting rods 118 which are supported at their lower ends on eccentrics 119 carried by a cross shaft 120. The shaft 120 maybe driven from the shaft 65 through a sprocket 121 on the shaft 120, a sprocket chain 122 and a sprocket 123 on the shaft 65. The machine may perform all of the above described operations upon a strip passing through the same or, if desired, it may be adapted to perform only some of the operations. The perforating bars and punches are removable and in cases where the punching and perforating operations are not desired, the perforating bars and punches may be omitted. If it is desired to omit the printing operation, all that is necessary is to disconnect the link 27 from the eccentric 28 and prop the head 19 in its uppermost position. The trimmer knives 114 are simply adjusted to positions adjacent the ends of the shaft 104 so that the strip can pass freely between them when the trimming operation is omitted. The shear blade 116 may be rendered inoperative by disconnecting the sprocket chain 102. Obviously, any desired combination of the operations which the machine is designed to perform may be performed upon a given strip of material passing through the machine.
