6 Claims.
This invention relates to improvements in manifolding means for printing business ma-- chines of the kind adapted for the use of .a plurality of superposed continuous paper webs formed by longitudinal folding of a continuous paper strip of sumcient width to provide the required plurality of superposed webs.. In such -manifoldi'ng equipment, the several webs frequently are slit apart along the longitudinal folds, before they reach the printing mechanism, by means of slitter blades mounted adjacent the path of the paper webs and entering between adjacent webs across'the fold lines at which adjacent webs are connected at their adjacent lateral edges. Some or all of the webs may have perforations at spaced intervals adjacent their lateral edges, such that the ends of the slitter blades may occasionally catch in the perforations and cause tearing and spoilage of sections of the paper web. As the superposed webs provide successive sets of registering forms, the tearing and spoilage of a section of one web necessitates discard of a section of each of the other webs, so that the waste of paper is quite considerable in addition to the loss of time and effort of the operator.'
An object of the present invention is'to provide, in a manifolding means of the kind mentioned, a guide means in conjunction with the slitter blade to prevent the end of the slitter blade from engaging in the perforations of the paper webs and damaging them or causing loss of time and effort of the operator,
The perforations formed in the edges of the.
paper webs supplied for various purposes and by various manufacturers vary considerably in size, form and location. A further object of the invention is to provide a guide means of the kind referred to above which will be efllcacious when used with continuous paper webs having perforations of various forms, sizes and locations.
In-manifolding means of the kind referred to above the superposed paper webs, particularly the outermost webs of a set. may be bent at a considerable angle over the edge of, the blade or guide extending between'them, particularly as the superposed webs pass through a pair or pairs of guides or pressure rollers before reaching the slitter blades andare again pressed together before reaching the printing mechanism. A further object of the invention is to provide, in conjunction with a'slitter blade, a guide means which will decrease the acuteness of the bending of the paper webs where they pass the ends of the slitter blades.
A further object of the invention is to provide, in conjunction with a slitter blade, an efllcacious guide means. which is simple and inexpensive to manufacture and requires in its production the use of only a minimum amount of metal.
Further objects and advantages of the invention will become apparent from the following description.
One embodiment of the invention is illustrated, by way of example, in the accompanying drawing, in which-' Figure 1 is a perspective view of a movable carbon carrier frame of a manifolding means for use with typewriters, and to which the invention has been applied;
Fig. 2 is a vertical section on the line 2-2 of Fig. 1 looking in the direction of the arrows; and Fig. 3 is a right-hand side view of a portion of a slitter blade provided with the guide means of the present invention, and illustrating the I manner of cooperation of the guide means with a paper web.
In the drawing, the invention has been illustrated, by way of example, as applied to the maniiolding means of the Butler Patent No. 2,136,671. -As in the Butler patent, the manifolding means comprises a carbon carrier] frame supported rearwardly of the paper carriage (not shown) of a typewriter or other printing business machine for movement toward and from said paper carriage on a track frame (not shown) attached to said papercarriage. The carbon carrier frame comprises a supporting plate 20 supporting a pair of shafts 2| on which are mounted pressure rolls 22 yieldingly pressed toward each other by springs 23 connected between the carrier plate 20 and arms 24 carrying one of said shafts-and pivoted on the plate 20. The blades 26, to which carbon sheets 25 are adapted to be attached by means'of clips 21, are apertured to permit said bladesto be stacked on upstanding studs 28, secured in the carrier plate 20, after said blades and the attached carbon sheets have been placed between successive webs 30a, 30b, 300, etc., of a set of superposed paper webs passing forwardly between the pressure rolls 22 from a supply (not shown) located at the rear of the machine.
When the set of superposed paper webs 30 is formed by longitudinal folding of a strip having an original width equal to the combined widths of the superposed webs and carbon supporting blades 26 of the kind shown in the drawing are employed, it is necessary to slit the webs apart along their connected lateral edges prior to the time that, they reach the carbon supporting blades in their forward travel. For this purpose, each carbon supporting blade 28, formed preferably of relatively thin, fiat steel strip, has ad justably mounted thereon a slitter blade 8| which is formed preferably of thin, flat steel preferably of a thickness less than the thickness of the blade 26, and which is attached to the carbon supporting blade 26 for adJustment lengthwise of said blade 26, by having four lateral lugs 32 on the supported end of the slitter blade 3| bent around the carbon supporting blade 26. From the portion supported on the carbon blade 26, the slitter blade 3| is inclined rearwardly and inwardly toward the path of the paper webs and has its free end inserted between two paper webs inwardly of their lateral edges, which are connected together along the line of folding so that, upon relative movement between the carbon carrier frame 20 and the superposed paper webs as the necessary records or data are printed 'on the successive sets of forms on the paper webs, the inclined slitting edges of the slitter blades 3i will separate the connected edges of the superposed webs just rearwardly of the carbon supporting blades-26.
As the webs of each adjacent pair of superposed webs, such as 3041 and 20b, 30b and 300, etc., are connected together at alternate sides of the set of webs, the slitter blades 3| on successive ones of the carbon blades 28 mounted on the studs must be located at alternate sides of the path of the paper webs. However, the carbon supporting blade and slitter blade assemblies are all identical and the slitter blade 3| may be located at either margin of the set of webs by merely turning the carbon blade 26 over end for end.
One or more of the paper webs of each set 30 of superposed paper webs may be perforated along one lateral margin or the other to permit one or more of the forms of each set of forms printed in the machine to be bound in loose-leaf binders. The perforations on different sets of webs may be of various shapes and sizes and formed at various positions on the paper webs as indicated for purpose of illustration at 33, 34 and 35 in Fig. 1, though it will be understood that usually only one form of perforation will be used in one set of webs. It, therefore, frequently happens that, during relative movement between the paper webs and the slitter blades 8| as successive sets of forms are printed in the machine, the slitter blades may engage in the perforations in the paper webs and damage or spoil sets of forms, thu causing waste of material and loss of time and efiort of the operator. To eliminate that dimculty, guide members 36 are pivotally mounted on the free ends of the slitter blades 3i located between the paper webs.
The guide member 36 is preferably formed of a length of preferably steel wire bent substantially as shown in Fig. 1 to provide a straight shank portion 31 which is received in the cylindrically bent free end 38 of the slitter blade to permit the guide member 36 to pivot freely on the end of the slitter blade 3| along an axis transverse to the travel of the paper webs. From this shank portion 31, the wire forming the guide member is curved rearwardly and then laterally inwardly toward the center of the paper web and has its other end bent into a substantially closed loop which approaches relatively closely to the end of the shank portion 31 so that the wire forms two substantially closed loops somewhat similar to a script J or "I" with portions to support a paper web on opposite sides of the pivotal axis of the guide. The bending of the wire is preferably such that all portions of the guide member 28 lie in substantially a single plane, as shown in Fig. 2.
The straight shank portion 21 of the guide member received in the cylindrically bent end 28 of the slitter blade permits the guide member 38 not only to pivot freely, as already stated, but also permits adjustment of the guide member relative to the slitter blade 3| transversely of the direction of travel of the paper webs.
The guide member 36 not only prevents the edges of the perforwations I2, 84 and 25 in the paper webs from catching on the slitter blade II or guide member 28 and thus becoming damaged, but also substantially eliminates another cause of occasional damage and spoilage of paper in that it reduces the acuteness of the bending of the paper web where it passes over the end of the slitter .blade, particularly in the case of the uppermost and lowermost blades 2i when four or more carbon supporting blades and slitter blades are required to be stacked on the studs 2| where five or more superposed paper webs arebeing used. The paper webs are caused to diverge vertically as they reach the ends of the slitter blades 8! in their passage forwardly from between the pressure rolls 22 and then continue forwardly substantially parallel to each other until they have passed the carbon blades, 28. The necessity for keeping the dimensions at a minimum requires that the pressure rolls 22 be relatively close to the ends of the slitter blades 3|. Instead of permitting the direction of the outermost sheets from changing considerably as they pass over the ends of the outermost slitter blades 2|, the guide members 38 mounted in the ends of said slitter blades cause the change of direction of the sheets to be effected at a plurality of separated points so that the change of direction of the sheets at each of these points is only a fraction of that which would otherwise occur as the sheets pass over the ends of the slitter blades. As shown in Fig. 3 the bending of the sheet 209 will occur substantially at points a: and 11 where the sheet first encounters and where the sheet leaves the guide member 30, as well as where the sheet contacts the cylindrically bent end portion 38 of the slitter blade, so that the change of direction of the sheet is effected in stages at three spaced points in the vicinity of the end of the slitter blade and is not sharply bent at any of these points. Also, the guide 38 supports a portion of the paper web having considerable area and so minimizes the possibility of the end of the slitter blade breaking through the paper web outside of the area of a perforation under any likely circumstances.
It will also be apparent from the foregoing that the construction is simple and inexpensive to produce and secures the objects of the invention with a great economy of metal.
While the exact form of the invention above described and shown in the accompanying drawing is admirably suited to achieve the objects of the invention, it will be apparent that the invention may also be embodied in other forms within the scope of the appended claims.
