The principal object of this invention is the provision of a bookbinding method and means for securing sheets, pages or leaves together in loose-leaf fashion, that is to say, in an assemblage in which the several leaves or pages are not secured to each other at thebinding margin, but are each freely strung on the binding means,
- as distinguished from the closed type of binding in which the leaves are sewen, glued, or stapled as paper, sized cloth, and like materials of relativeh flexible quality adapted to take an adhesive or agglutinant employed in the binding.
A further object is the provision of a binding in the form of an elongated strip having a plurality of binding fingers projecting laterally therefrom at intervals along the length of the strip, the fingers being adapted to pass through slots in the leaves to be bound and then turned back for engagement between lips or flanges forming part of said strip.
A further object is the preparation of the binding strip in laminated form from superimposed elongated strips of paper or the like, which have been glued together throughout their length excepting along one longitudinal edge, the unglued or unattached edge portions providing the separable lips or flanges aforesaid, and the binding fingers or prongs being stamped or'otherwise cut portions, whereby separable lips or flanges are provided along said longitudinal edge portions, the glued strips being cut in appropriate lengths, and thereafter being subjected to a stamping operation in which the binding fingers or prongs are formed, said stamping operation being effected in a manner to provide two complete binding strips from each severed length of tape. e
Other objects relate to the provision of .a binding consisting of an elongated strip portion with lateral binding fingers adhered to the strip portion after being passed through the matter to be bound; to the provision of opposite flange or lip portions on the strip portion for securing the endsof the binding fingers; to the method and means for preparing binding strips with a minimum wastage of strip stock; and to the various features of novelty and utility which will appear hereinafter asthe following description proceeds in view of the annexed drawings in which:
Fig. 1 is a perspective view of the strip-forming means which employs a the strip stock;
Fig. 2 is a erspective view of a prepared strip which has been stamped or die-cut to form-two bindings;
Fig, 3 is a perspective view of the stamped stri of Fig. 2 after the two bindings have been separated, following the stamping or die-cutting operation;
Fig. 4 is a perspective fragment of a book with the binding inserted preparatory to the formingup operation; Fig. 5 is a perspective fragment of a book with the binding formed-up or completed;
Fig. 6 is a perspective view of a modified stripforming means adapted to the employment of glued strips or stock.
Referring to Fig. l, the novel binding is prepared by a process which employs two rolls 20 and 2| of paper or cloth tape which ranges from one and one-half to,two inches in width,- depending upon the length of binding finger or prong desired.
Theunderside of the top roll 20 is coated with a heat-fusible adhesive 22a of known type commonly available on the open market, while the upper side of the lower roll 2| is coated with a layer 22b of the same kind of adhesive (the adhesive on both strips being indicated by the mottling thereon).
The free ends of each strip are fed in superimposed relation, with their adhesive surfaces engaged, between forming rollers 23 and-24 so as to be pressed firmly together. One of the forming rollers, preferably the lower one, 24, has a hollow shaft 24a into which .is fitted an electric heating rod or coil 25, adapted to heat the lower roller 24, which is of metal.
As the superimposed strips are pulled through the forming rollers (by means not shown), the lower heated .roller 24 causes the adhesive on bothstrips to fuse, and the resulting coherence secures the two paper or cloth strips together in the manner illustrated by the formed portion of thezistripping issuing to the right of the rollers, a
An important feature of the process resides in the provision of beveled edges 23a and 23b at,
heat-fusing adhesive on each end of the upper roller 28, which results in leaving the opposite longitudinal edge portions 11 and 28 of the formed strip unattached, so that a pair of divergent lips or flanges 21a and no, on
one side, and 28a and 281: on the other side, are provided along the opposite edges of the strip.
It is important in the method of preparing these binding blanks or strips, that the web or stock strip 20 or 40, which is to be biased or curled, shall be fed between the rollers 23 2, or '45, 48, at an angle A' (see Figs. 1 and 6) of approximately 30 to 40 to the plane of movement both rollers in the plane of movement of the composite strip between the rollers, and therefore the strip' portion which is to be curled should be fed at an angle A away from this tangent and in a direction away from the other strip.
Any kind of adhesive or gluing substance may be used in the process with either paper or cloth or similar fibrous stock; and the strips may be pre-coated, or the adhesive or agglutinant may be applied just prior to feeding the strip stock into the pressing members or rollers.
In order to apply the curl or bias which results in the edgewise flanges or lips, the beveled roller, at least, should be about as wide as the strip or web stock, as shown in Fig. l; and the width of the beveled surface or curling formation should be about the width of the desired flange or lip portion.
The formed strip 28 is next out off at a desired length and placed in a stamping or die-cutting machine (not shown), and a series of alternate prongs or fingers is cut through so that two complete bindings 21:: and 28:: are formed (see Fig. 3), each binding having its own set of spaced, laterally-extending binding prongs or fingers 21x11 and 2821!, respectively. These individual bindings are now ready for use.
As illustrated in Fig. 4, a stack of leaves to be bound, 29, has prepared therein a series of binding slots 30 extending along the binding margin thereof, each slot being of a width to receive a corresponding one of the fingers 28x11, for example; whereupon the binding strip 21:: has its several fingers inserted in the slots 30, prepar- "biasproduced by the bevel means atory to the forming-up operation and insertion of the fingers between the lips or bifurcations 28 28b. 1
In a modified form of binding, illustrated in Fig. -6, the adhesive coatings 42a and 42b are of the water-soluble kind, such as ordinary animal glue, and the underside of the top strip passes over' a moistening means, such as the brush 3, rotating in a water pan 44, so that the adhesive coating mat-least, is moistened, and thereafter caused to adhere to the lower strip in passing.
beneath the pressure rollers 45 and 46. Roller 45 has opposite end portions beveled as at 45a, D, as in the method of Fig. 1, but the heating means 24a of Fig. 1 is omitted in Fig. 6.
In other respects, the composite or formed strip portion 41 issuing from between the presser rollers, is identical to the strip portion 26 of Fig. 1, opposite divergent or open flange or lip portions 484, "b, on one side, and 49a, 49b on the other side, being formed as in the first method of Fig. 1. Moreover, the glued strip portions, after being cut to desired length, are stamped or die-cut. as 7 in Fig; 2, to provide two complete binding strips or blanks of the type shown in Fig. 3.
It may be noted that in both methods oi forming the novel binding (Figs. 1 and 6) the flanges 21a, 2'"), or 49a, 49b, respectively, tend to remain spread apart, owing to a curling effect or bias imparted by the combined eflects of adhesion and 23b or "D, as the case may be. 7
Numerous advantages attach to the novel binding means, and important economies in material result irom the method of forming the bindings. The paper or cloth stock used in preparing the binding strips is of non-critical nature and may be easily obtained; the mechanism necessary for the preparation of the binding strips is simple and easily manipulated, and the resulting binding is adequately strong for mostly all binding purposes, the cloth binding being exceptionally satisiactoryin this respect, and nearly as cheap as the paper type.
By forming or cutting two individual binding pieces from a single formed strip in the manner illustrated in Figs. 2 and 3, wastage is reduced to a minimum. The bindings are light in weight and may be shipped in large quantities at little expense, taking up little roomin stock quantities. Also, the material of which the bindings are fabricated lends itself to the receipt of an imprint of identifying data, which is frequently important in bookbinding to keep jobs separated. Moreover, the bindings are so light and flexible that they conform themselves very readily to the shape of the backbone of the bound sheaf and assist in permitting the bound leaves to turn easily and lie open.
While paper, cloth, particularly sized cloth familiar in the bookbinding arts, and analogous materials like cardboard, are suggested as suitable materials for the novel binding, the use of other materials of equivalent qualities adapted to the various operations of the binding process, are all contemplated by this disclosure, the invention is not intended to be limited to the precise details set forth herein for the purposes of illustration and description, excepting only as may be expressly provided in the appended claims.
