7 Illinois Application January 11, 1940, Serial Noh313,366 s .Glaimsr (c1. 2s2 12) This invention relates to nianifolding assemblies of the continuous web type'in which there are superimposed strips or webs 'of paper printed I and arranged to comprise a long series of'suc- -5 cessive forms separated by transverse lines of severance whereby theindividual forms or packs can be torn off from the strip, and having marginal "feedband perforations for use in typewriting machines equipped with pin-feed devices ill whereby the forms and their copies arekepti accurate registration with each other.

The main object of this invention. is to provide an improved construction for the transfer strips of such manifolding assemblies whereby inherent compensation is provided for relative differences of contraction and expansion that may result from air conditions or other factors that have a different effect upon the record strips and the transfer strips due to the factfthat said strips. '20 may be respectively of difierent kinds and thicknesses of paper.

According to the present usual practice, continuous manifolding form assemblies are made up of a plurality of separate record'andcopy strips having printed forms in registering relation, and

of single form width, or of multiple form width fanfolded on longitudinal lines. In either case 7 the record and copy strips are interleaved with transfer strips usually of carbon paper andthe whole assembly is then. zigzag folded by creasing it in successively opposite directions on the transverse severance lines between. successive forms.

In manifolding-assemblies of this kind, especially those which are designed for use in machines having the pin type of feed, the pin-feed devices tend to bring the forms and transfer sheets into registration at their marginal feedband apertures and if the transfer sheets have become displaced by reason of differences of expansion of their substances as compared with that of the record and copy'sheets in passage through the typewriting machine, it is important that they be so constructed as to avoid wrinklingform.

there may have been. some shifting of the'transfer strip either by expansion or contractionor by operation of the feeding mechanism.

A specific embodiment of this'invention is 11- lustrated in the accompanying drawing in which! Figure 1 is a fragmentary top view of-a manifolding assembly, partly broken away in such manner as to show the structure of the different layers. I

Fig. 2 is a perspective view of such an assembly ii) zigzag folded in a multiple form pack. 3 is a fragmentary face view illustrating a modified form of the assembly shown in Fig. 1.

Fig. 4 is a similar view of a further modified it In the form shown in Fig. "1, the essentials of r such an assembly comprise a record strip I, a

copy strip 2, and an interposed transfer'strip 3.

There "may, of course, be any numbercf copy sti'ips'up'to the capacity of thetypewriting m'a- 20 chine for making simultaneous copies and there ma'y be a corresponding numberof transfer strips.

These strips may all be'separated from each other, as illustrated in the drawingor theymay 525 be of the well-known. fanform type in which-one or more of "the copy sheets is integral with the record sheet and brought into manifoldingrela- The individual record forms that make up the strip 30 fare separated by the usual transverse severance lines 4 which are weakened for tearing the forms apart, either by scoring or by a line of closely spaced perforations. I

The assembly is provided on one or both of its '35 longitudinal margins with feed-band perforations 5 which are accurately spaced to cooperate with the pin-feed devices of the typewriting machine of any of the many types of machines in which such forms are used. 40

According to the present invention, the transfer sheet, instead of having a single line of weakness corresponding to the severance lines 4 of the record, has a band. 6 or weakened area of considerable width extending across it in approximate registry with each of the severance lines of the record sheet. In the form shown, this band 6 is made up of a plurality of closely spaced lines of weakness extending parallel to each other across the width of the strip and each comprising a series of perforations similar to those which make up the tearing lines of the record sheet. It is, however, preferable to have the perforations in the individual lines of weakness spaced apart at less distancethan the width of ATENT otrrics the stock that is left between these lines of weakness, so that as the form lengths are torn apart, the transfer sheet will tear on straight lines.

It will be seen that there may be expansion, or contraction, or relative shifting of the record sheets and transfer strips to any extent within the limits of the width of this band of weakness without any disturbance to the folding of the assembly on the transverse severance lines of the strip or the tearing of the entire pack throughout its depth in registry with the lines of weakness of the record forms.

In the modified form shown in Fig. 3, the feedband perforations 5.! in the transfer sheet are substantially larger than the feed-band perforations 5 of the record and copy sheets.

In the modification shown in Fig. 4, the transfer strip is made narrower than the record and copy strips so that its side marginal edges 1 will completely clear the pins that engage thefeed band apertures 5 of the record strips.

It will be understood that details of the construction shown may be altered or omitted without departing from the spirit of this invention as defined by the following claims.

I claim:

1. A continuous web manifolding assembly comprising superposed record, copy and transfer traveler strips, said record strip having transverse lines of severance defining individual form lengths, and said transfer strip having, in approximate registration with each said record severance lines, a plurality of closely spaced parallel transverse severance lines.
