However, in this case I cement the strips I9 to 25 the outer ply I I only and donot cement the side panel portions l5 and [6 of the separate plies ' together (see Fig. 2).

To do this I cement a cardboard strip 20 along the outer edge of the panel l5, the cement'bein-g applied along the short edge 2! of the inner ply I0 only.

I will also mention one or two useful modi?cations wherein the pocket lining matching the rest of the binder cover making problem is solved with‘ variations.

The cardboard flap 2!! has now been attached "and will be referred to .as the inner ply is per ' binder casing ‘starts with two plies of thin card‘ "board ' H1 and‘ ‘ H, which? both have‘ the over its forated, scored, or otherwiseweakened alongv two to the ply I705 along the outer-edge of panel I5 55 2 2,105,232 and is closed along its two shorter edges by the while strips I9 adhere to ply II only. Punches edge portions 24 of the cover sheet 23. In this manner I have provided a pocket with its open ing 25 towards the back panel portion I4 of the 46 make the rivet holes I8 in strip I'I before the binder case. This is the preferred form to obtain the ut most in economy of pocket construction. ,How ever, if a sturdier construction is desired at slightly higher cost per unit, I cement a stay of 10 kraft paper along the short edges of the pocket before the cover sheet 23 is applied. This in sures that the pocket will not tear loose along the turned edges 24 of the cover paper. The portions 22 of the inner ply I0 lying be 15 tween the perforation lines I 2-I2’ and I3-—I3’ are now removed, the ends being slipped out from under the edges 24 of the cover sheet 23. The side panel portions I5 and I6 of inner ply III are now held in position only by the edges 24 of 20 the cover sheet and may slip slightly relative to the corresponding panels of ply II. The portions of ply I I uncovered by removal of strips 22 serve as hinge lines or zones to allow the side panels I5 and I6 to be opened or closed as the book is used, the relative motion of the side panel pieces I5 and I B of each ply I0 and II serving to facilitate this motion. A single lining sheet 30 is pasted over the back panel portion and the side panels of ply III, in cluding the pocket of panel I5. The opening 25 of the pocket is then freed by slitting the liner sheet. The back panel portion I4 may then be pressed to a curved shape or left ?at and the ring mechanism 35 installed to complete the ring 35 binder shown in Fig. 1. The particular construction used in applying the liner sheet and ring mechanism can of course be varied to provide a ring binder of higher quality. For instance, a liner sheet may be ap 40 plied from the free edge of panel I6 to the open ing 25 of the pocket. A separate liner may then be pasted to the pocket extending from the outer edge of panel I 5 with a portion of the liner sheet turned under the pocket edge 25 to present a 45 neater appearance. In a still more expensive type I can use a sepa latter enters the rolls 40 and 4|, and a suitable cutting tool 41 cuts off the webs into units hav ing the structure of Fig. 2. As will be appreciated from the above descrip tion and drawings, by my invention I have pro vided for an improved ring binder which can be manufactured in quantities at low cost but which ‘has the more desirable features not found in this class of product in the cheaper quality binders. The incorporation of a pocket in the side panel of a binder has always been desirable, but special operations have heretofore been necessary, which so increased the cost per unit as to make this feature unavailable in all but the expensive ring binders. What I want to particularly emphasize is that by using the method outlined above it is possible to incorporate the pocket in the binder and keep the additional cost down to little more 20 than the cost of the pocket material itself. What I claim is: 1. The method of making loose leaf binders which consists in simultaneously feeding strips of cardboard of inde?nite length from rolls, at least one of said strips having a width equal to the overall width of the binders to be built and at least one of which has a width equal to the width of a pocket to be built on the inside face of one of the binder cover portions, the outer 30 edge of the latter strip being fed in alignment with an outer edge of the cover portion and with the strip contacting the inside face of such por tion, and also simultaneously feeding from a roll a narrow strip of stiffening material in line :‘" with the cardboard back panel portion of the binders to be built, progressively fastening the outer‘ edge portions of the cardboard strips and the strip of stiffening material to the back panel portion by passing the same through pressure 40 rollers, progressively cutting off said laminated and fastened strips in lengths equal to the height of the binders to be built, and then laying on the outside face of each cut-oil’ skeleton binder a layer of cover material with edges extending 45 beyond the overall dimension of the skeleton so rate lining sheet of heavy paper or fabric for as to turn over all around on the inside margin the back panel portion I4, making it wide enough of the skeleton, turning over and fastening such edge portions around the overall dimensions of the binder skeleton and ?nishing the binder by 50 laying on usual lining strips on the inside face but without permanently closing the open end of the then formed pocket. 2. The method of making loose leaf binders to just overlap the hinge zone on each panel. 50 Then suitable lining sheets may be applied to each side panel. This construction is in many ways most desirable where the binder suffers rough usage as the hinge line of the side panels is materially strengthened. Of course many variations of methods of ap plying the lining sheets will occur to those skilled in the art and I in no way limit myself to the particular arrangement described. I carry out my construction method with card 60 board plies and reenforcing strips in web form, as shown diagrammatically in Fig. 5. In that ?gure, cardboard plies I0 and II and ?ap 20 are fed from supply rolls not shown between presser rolls 40 and 4!. The perforation lines 65 I2-I2' and I3-—-I3’ are made by a- suitable Wheel 42' before the ply II! passes through the rolls. Similarly cement is applied to the web 20 by roll 42, roll 43 being merely a supporting roll for that portion of the web 20to which adhesive is not applied. The metal strips I ‘I and I9 are fed in proper spaced relation through the presser rolls 4!] and 4| from suitable supply reels, as indicated. Adhesive is applied to both sides of strip I‘! and the under side only of strips I9 by the rolls 44. 75 Thus, strip I ‘I adheres to both plies I II and II, ' composed of plies of cardboard having the over all ?at dimensions of the casing to be built which comprises securing said plies together over those portions only of the plies which are to become the back panel of the casing, cementing a narrow cardboard ply with one long edge along one short edge of the inner ply, applying a cover sheet to the exposed face of the outer ply, said sheet being of greater overall dimensions than the casing, turning over and cementing the edge portions of the cover sheet to the exposed face of the inner ply and along three edges of the narrow ply, removing a narrow strip of the inner ply adja cent each side of the back panel portion of the inner ply, applying a single lining sheet cover ing the‘ inner ply and exposed edge of the nar 70 row cardboard strip, and then slitting the lining sheet along the uncemented long edge of the narrow cardboard strip to form a pocket. 3.
