IMPROVEMENTS IN OR RELATING TO STATIONERY BINDERS
[0001] This invention relates to a method of making a stationery binder which, at an intermediate
stage of manufacture, is a loose-leaf binder and which, at a final stage of manufacture,
is a binder for permanently binding stationery.
[0002] If companies wish to send out, or to use internally, brochures, specifications, reports,
tenders etc., they have, apart from a loose-leaf format, two main options. The first
is to go to their printer and the second is to buy one of the various machines available
and bind the copies themselves. For the first option to be viable, a large number
of copies would be required and there would be little chance of altering the data
sheets to suit one customer in particular. The second option necessitates a capital
outlay for the equipment plus, of course, a separate supply of covers.
[0003] The primary object of the present invention is to provide a binder which would enable
the user to bind in a permanent fashion data sheets etc. without machinery and with
total flexibility of content. An intermediate stage of the manufacture of the binder
according to the present invention provides a loose-leaf binder.
[0004] According to one aspect of the present invention, there is provided a method of making
a loose-leaf stationary binder, comprising the steps of folding a substantially rectangular
sheet along first, second and third equispaced parallel lines across the sheet to
form a ridge across the sheet so that one side of the sheet has, from end-to-end,
a major face, then two minor faces forming the ridge and then another major face;
inserting a stiffened flexible strip through two holes in one of said minor faces
so that a central portion of said strip extends along the other side of said sheet
and the two ends of said strip extend out of said holes on said one side and transversely
of said sheet, the ends of said strip being intended to be passed through file holes
in sheets of paper in use of the binder; and joining the rear sides of said two minor
faces together to form an inner spine of the binder and to hold said strip in place.
[0005] According to a second aspect of the present invention, there is provided a method
of making a binder for binding stationary in a permanent fashion, the method comprising
all of the steps defined in the preceding paragraph and then applying one side of
a double-sided adhesive strip adjacent said stiffened flexible strip, said adhesive
strip being positioned so that the other side of said adhesive strip can be applied
to cause part of said major face that lies adjacent the free ends of said stiffened
flexible strip to entrap said stiffened flexible strip and to obscure it from view.
[0006] According to.a third aspect of the present invention, there is provided a stationary
binder as produced by the method essentially as defined in either of the two preceding
paragraphs.
[0007] For a better understanding of the invention and to show how the same may be carried
into effect, reference will now be made, by way of example, to the accompanying drawings,
in which:-
Figure 1 is a diagrammatic view of a first form of binder in an opened-out condition
at an intermediate stage of manufacture,
Figure 2 is a diagrammatic end view of the binder shown in Figure 1,
Figure 3 is a view similar to Figure 1 of a second form of binder, and
Figure 4 diagrammatically illustrates the spine of a completed binder according to
Figure 1 or Figure 3 with papers permanently bound therein.
[0008] Referring firstly to Figures 1 and 2, the binder is made by providing a substantially
rectangular sheet A, which can be of card, and making score or fold lines in it from
top to bottom. In the Example shown, four score lines 1, 2, 3 and 4 are provided,
the score lines 2, 3 and 4 being equispaced from one another. Two holes 5 are punched
in the sheet A between the score lines 2 and 3. The score lines 2, 3 and 4 are gathered
together to form two folds in the sheet A which thus forms a ridge across the sheet
so that one side of the sheet has, from end to end, a major face 8, then two minor
faces 9 and 10 forming the ridge and then another major face 11.
[0009] A stiffened flexible strip 6, which may be of metal or plastics material, is inserted
in the two holes 5 so that a central portion of the strip 6 extends along the other
side (outside) of the sheet A and the two ends of the strip 6 extend out of the holes
5 on one side and transversely of the sheet. The ends of the strip 6 are intended
to be passed through file holes in sheets of paper in use of the binder, the ends
being bent over inwardly towards one another to lie flat one on the other.
[0010] The two folds, i.e. the rear sides of the two minor faces 9 and 10, are then joined
together, preferably by glueing, to form an inner spine for the binder and to hold
the central portion of the flexible strip 6 in place.
[0011] A separate strip 7 of card with two holes therein is provided to strengthen the binder
by helping to prevent the flexible strip 6 from tearing the puched holes in the papers
in the binder, the strip 7 lying on top of the papers with the ends of the strip 6
passing through respective holes in the strip 7 and being bent over onto the strip
7.
[0012] In this condition, the binder is in a loose-leaf format so that it is possible to
insert and remove at will material held by the strip 6 in the binder.
[0013] To form the binder into one for binding in a permanent fashion, one side of a double-sided
adhesive strip 12 is stuck onto the major face 11 between the score lines 1 and 2.
A protective paper strip is provided on the exposed side of the adhesive strip 12.
In this condition, i.e. with the flexible strip 6 and the separate strip 7 of card
in position and the adhesive strip 12 affixed to the face 11 alone, the binder can
be sold.
[0014] In order to bind material in, data sheets, etc. with punched holes are inserted over
the end of the strip 6, then the strip 7 of card is placed on the strip 6 over the
data sheets and the ends of the strip 6 are bent over, preferably towards one another
but they could be bent away from one another. The protective paper is lifted from
the adhesive strip 12 and the back cover (11) of the binder is folded over. The adhesive
adheres to the strip 7 of card which is held with the data sheets by the strip 6.
The strip 7 in this condition completely obscures the ends of the flexible strip 6.
The result is a binder with the internal sheets securely bound and the clip hidden.
There is no plastics spiral or strip to spoil the appearance. Figure 1 shows a fourth
score line 1 which is provided to enable the major face 11, which has now become the
back cover of the binder, to be opened easily.
[0015] Figure 3 is a view similar to Figure 1 but shows a second form of binder in which
the positioning of the adhesive strip 12 has been changed from the back cover 11 (where,
in Figure 1, it was lying adjacent the flexible strip 6) to being provided actually
on the strip 7 of card, so that it still lies adjacent the flexible strip 6. Effectively,
therefore, the position of the adhesive strip 12 has been reversed. The adhesive strip
12 is shown cross-hatched in Figure 3. In addition, both the strip 7 of card and the
adhesive strip 12 are shorter in the form shown in Figure 3 as compared with the form
shown in Figure 1.
[0016] It will be seen that, with the form shown in Figure 3, when the ends of the flexible
strip 6 have been bent over to lie flat on one another and when the protective paper
strip has been removed to expose the adhesive strip 12, the back cover 11 can be folded
over so that the adhesive strip 12 will stick to the back cover 11 between the score
lines 1 and 2 thereby to entrap the flexible strip 6 and'to obscure it from view as
with the Figure 1 form.
[0017] If only a non-permanent binding is required, the strip 7 of card is preferable reversed
so that the adhesive strip 12 with its protective paper faces downwards so that the
binder can be used as a loose-leaf binder. If, at a later date, a permanent binding
is required the strip 7 of card can be removed and then replaced with the adhesive
strip 12 face up, the protective paper is removed and the sheet can then be permanently
bound.
