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

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.
