Patented Apr. 24, 1934 UNITED STATES PATENT OFFICE Meisel' Press Manufacturing Company, Boston, Mass, a corporation of Massachusetts Application July 25, 1933, Serial No. 682,083

9 Claims.

Business forms arein common use which embody sheets, usually with identical or complementary printing thereon and either with or without permanently associated carbon sheets between them, in which the sheets are fastened together along an edge forming a book-like pad. Such fastening is effected by adhesive, wire stitching or other means. Wire stitching has obvious disadvantages, and especially when the number. of sheets increases, securing them together by means of adhesive has hitherto entailed the multiplication of expensive'mechanisms in manufacture and objectionable bulkiness at the joint. My invention provides for the production of a multiplex form obviating such criticisms.

My invention may be well understood by reference to the following description taken in connection. with the accompanying drawing, wherein:

Fig. 1 is a. diagrammatic view illustrating a method of production;

Fig. 2 is a broken plan'view of a portion of a number of webs united in a manner illustrative of the invention, which webs may be divided to provide a plurality of forms;

Fig. 3 is an enlarged section on theline 3-3 of Fig. 2; and

Fig. 4 is a view of a pad with the parts thereof I separated and with part broken away.

As an example of my invention I will here illustrate and describe a pad or form consisting of five parts or shee s 1, 2, 3, 4 and 5, of which, for example, sheets 1, 3 and 5 may be of paper, for instance blank forms, adapted to receive inscriptions, and 2 and 4 may be carbon transfer sheets. The pad is preferably forrried from lengths of indefinite length, such as mill rolls such as'are utilized on printing presses of the web type, as distinguished from sheets of which the dimensions although perhaps large are not greatly dissimilar. In Fig. 1 I have shown five su'ch webs with the numerals 1, 2, 3, 4"and 5, these being the same numerals as applied to the sheets of the pad as it will be understood that the sheets- 1 are sections of the web 1 and so on, andI have there illustrated them as drawn from rolls shown at the left-hand side of Fig. 1. It will be understood that the several webs may be of the same stock or dissimilar in quality, color, etc., as may be desired. Herein the webs 1, 3 and 5 are shown as drawn forward through a printing mechanism 6. The webs are fed forward longitudinally and brought together as illustrated at the right of thefigure in superposed position with atleast one of their edges in alignment.

edges thereof with openings. preferably in the The manner in which the webs are connected will be apparent from Figs. 2 to 4. The webs 2, 3, 4 and 5 may be provided along the aligning form of holes 20, 30, 40 and 50 respectively. I have herein illustrated in Fig. 1 these holes as being made incident to the process of printing and aligning the webs, this being indicated by the diagrammatic showing of punching mechanisms 10. These punching mechanisms are 6 diagrammed as reciprocating punches cooperating with dies solely on account of the graphic nature of such a diagram.

The openings in the several webs are so located that marginal portions thereof are successively 7 displaced, preferably in the direction of the length of the web, so that the superposed webs as a whole present an opening extending through ,the

'20 as beinground, while the holes 30, 40 and 50 are successively more and more oblate.

To secure the webs together I may utilize a flat member of thin sheet-like character adhesively secured to the face of the web 5 at the location of the opening 50, to the faces of the webs 4, 3 and 2 where exposed at the stepped margin of the opening, and through the opening to the end web 1 which presents an unbroken face at the bottom of .the opening. Herein I utilize a single member extending from hole to hole and in the form of a narrow tape 15 which, in the process of manufacture shown, may conveniently be of indefinite length like the webs and which may be drawn from a supply roll as seen at the right of Fig. 1 and pressed on to the assembled webs parallel to the aligning edges thereof as by means of the pressure rollers 16.

The tape is preferably of the type having a paper body provided with a pressure-sensitive adhesive coating such as a rubber and resin compound adapted to adhere to the several webs by mere pressure without the use of liquid and without requiring drying or heating. The tape may be provided on its opposite face with a finishing coating which not only permits the tape to be rolled up and readily to be withdrawn from 1 5 the roll for uniting to the webs, but also presents a smooth and non-tacky surface at the back of the finished form. At the front of the form the end sheet 1 covers the sticky surface. Smea'ring or subsequent cockling which might arise from 1 the use of drying adhesive are avoided when a pressure sensitive adhesive is used.

The united webs may be severed transversely to form pads for use. In a pad of the type shown the several sheets may be perforated adjacent the heads thereof as indicated by the line 17, and in normal use after being inscribed the connected parts may be torn off along this line to separate the sheets. It will be understood that I have shown a pad of five sheets with but two openings along its edge to simplify the drawing and that the number of sheets and the number of openings are subject to considerable variation.

It will be seen that the method of-manufacture is very simple and well adapted to continuous production, particularly in connection with machines of the rotary type. curely held together.

The parts are se- In the form shown slight inaccuracies in register of the parts will not shown in Fig. 3 without buckling or drawing since it may be drawn in as required although' a slightly greater length is required for each individual pad than the width of the pad and no error will be gradually accumulated to cause difiiculties.

I have used the word form to refer to the finished product and usually some or all of the sheets such as 1, 3 and 5 in the present instance would be printed on, usually to constitute a blank iorm which would be filled out on the typewriter or otherwise. It will be understood, however, that I use the word form in the claims merely as a convenient word to designate a booklet of the type under consideration and not by way of limit-Jim to the printed matter, if any, appearing upon the sheets.

I am aware that the invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and I therefore desire the present embodiment to be considered in all respects as illustrative and not restrictive; reference being had to the appended claims rather than to the foregoing description to indicate the scope of the invention.

. I claim:

1. A multiplex form comprising a number of superposed sheets having similrrly located but progressively enlarged openings therein, thus collectively presenting an opening .vith a stepped margin and a member, adhesively secured to the several sheets along said margin.

2. A mvktiplex form comprising a number of superposed sheets having substantially similarly located openings having marginal portions progressively displaced from sheet to sheet, thus collectively presenting an opening with a stepped margin and a member adhesively secured to the several sheets along said margin.

3. A multiplex form comprising a number'of superposed sheets having substantially similarly located openings having marginal portions progressively displaced from sheet to sheet, thus collectively presenting an opening with a stepped margin and a securing member adhesively seing and extending into the same and adhesively secured to the exposed stepped surface of the other sheets at said margin.

4. A multiplex form comprising an end sheet, other, sheets superposed thereon and having substantially similarly located openings havingmarginal portions progressively displaced from sheet to sheet, thus collectively presenting anopening with a stepped margin, said opening opposing an unbroken portion of the end sheet and a member adhesively secured through said opening to the end sheet and to said margin.

5. A multiplex form comprising an end sheet, other sheets superposed thereon and having substantially similarly located openings having marginal portions progressively displaced from sheet to sheet, thus collectively presenting an opening with astepped margin, said opening opposing an unbroken portion of the end sheet and a member of restricted area adhesively secured through said opening to the end sheet and to said margin.

6. A multiplex form comprising an end sheet, other sheets superposed thereon and having substantially similarly located openings having marginal portions progressively displaced from sheet to sheet, thus collectively presenting an'opening with a stepped margin, said opening opposing an unbroken portion of the end sheet and a member having a pressure adhesive coating overlying said opening and pressed thereinto into adherence with the margin thereof and with the end sheet.

7. A multiplex form comprising a pluralityof superposed sheets aligned along one edge and having along said edge substantially similarly located openings having marginal portions progressively displaced parallel to said edge from sheet to sheet thus collectively to present an opening having a stepped margin, and an adhesive 3.

comprising an end sheet and a plurality of other I sheets and having along said edge substantially similarly located openings having marginal portions progressively displaced parallel to said edge from sheet to sheet thus collectively to present an opening having a stepped margin, and an adlength aligned along one of their longitudinal edges and comprising an end web and other webs having along said edge substantially similarly locatedopenings having marginal portions progressively displaced parallel to said edge from web to web collectively to present an opening having I a stepped margin, which opening opposes an unbroken portion of the end web, an adhesive tape extending along said webs and secured to the web opposite said end web to the surfaces of other webs exposed at margins of the openings and through the openings to said end web, the assemblage being adapted for transverse division into pads.
