I In fanfolding paper such as' used in certain bookkeeping orrecord'keep'in systems, T

it has been'customary to first per orate the web of paper on the lines'on which the "fold is to be made andto subsequently crease the paper on these" lines by'separate mechanism to: cause the paper to fold in the'desired directions after it leaves 'the 'creasingme'chanism.

I find, h0weve'r,-that due to stretching of the paper it isverydifficult to keep the creasmatter how carefully the apparatus is operated, and therefore the paper does not always each line a fold is to be made maybe done simultaneously sotha't both the perforating and creasing will always be in alinement.

I attain my object by means of the constructions hereinafter described and illuswhich is to be fanfolded. From trated in the accompanying drawings in Fig. 1 is a more or less diagrammatic view showing one form of apparatus'for carrying out my invention; v 1 Z- Fig. 2, a similar viewishowing a modified form of apparatus; i

'Fig. 8, an enlarged sectional detail of the female member of the perforating and creasing mechanism; and p I I Fig. 4, an enlarged sectional detail of the male member.

In the drawings, like numerals of reference indicate corresponding parts in the different figures. I

Referringto Fig. 1, 1. indicatesa roll on which is positioned the web this roll the paper is led between two contacting rolls 3.

Each ofthe rolls 3 isprovided at diametrical points with a female member 4 and a male 'member 5, the male member 5 on the one roll being arranged to' co -act with the female member on the other roll. I

The female members 4 are each provided with a groove 6 extending longitudinally of the roll, and the'male members 5 are each provided with .a series of perforating prohereinafter appear, somewhat wider creasing will be done of paper 2 which ject'ions 7 arrangedlongitudinally,of the roll.

he grooves 6 are, for a purpose which will I than the perforating PIOJGCtlODS 7. 4

4' which are set into the surface of the rolls 3 are formed in two parts, each having a recess in their contacting faces in which is TBS PATENT; OFFICE As shown in Fig. '3,the female members received a bar 80f fibre or similar material,

the bar of fibre forming the bottom of the groove 6. Damage to the perforating projections 7 is therefore avoided as the fibre bar wlll give under the action of the perforating projections. 1 y f Themale members, which are alsosetinto the rolls 3 are formed in two'sections, 9' and 10, the sections being clampedtogether by screws ll to hold the toothed projections in position.

The operation of the apparatus above de- 'scrlbed is as follows. The paper is drawn from the roll 1 and is fed between the rolls'3, where'the male members 5 first forcethe paper into the grooves 6 inthe members Land then perforate the paper on spaced linesby pressure against the bottom of the groove, at the same time causing a creasing or folding of the paper which tends to further break the fibres of the papers 5 are arranged alternately on opposite rolls, it will be evident that'the perforating and alternately on opposite sides of the paper and consequently the paper as it leaves the rolls 3 will tend to fold alternatelyl in opposite directions to secure the proper-'fanfold arrangement. i

In Fig. 2 an alternative arrangement-is shown in which the paper is fed between rollers 13. v The female members 4 are arranged one at' one side of the paper and one at the other; the male members being arranged at the opposite side of' the paper to the female members. Means will be devised for alternately moving one member of each pair. 9

With this construction the paper-will be fed forward intermittently, the steps being equal to double the distance between folds and the set of co-operating members 45 will be arranged aparta distance equal to the distance between'the folds. I

As the members 4 and I 'isfact orily attain the ob OPPOSltflSldQS, said creasing and perforating r In the drawings, I show the upper members 4 and 5 as mounted on a. vertically moving framel l, which may be operated in any suit able manner, as for example, by a lever 15' as set out in this specification. v

What I claimas my invention is:"

1. In paper folding apparatus, the 001111 bination of apair of creasing and-perforating" members arranged one at each side of the path along whichpaper is to passwhereby the paper is creased and perforated from members I being; positioned relative to one another so that the creases and perforations made'by one member are alternated with those made" by the other member, and grooved members cooperating with and into which 1 saidcreasingand perforating members project torcrease' the paper along the'lines of perforations; thebottoms of said grooves "forming supporting surfaces for the paper while the perforatingis being effected. I

2.
