[0001] The invention relates to a separator for plates, in particular fragile plates such
as glass plates, comprising a strip of carrier material with a projecting nose near
one end.
[0002] Such separators are used in the glass plate industry. The glass leaves the glass
melting furnace as a continuous web, which is cut into plates, after which the plates
are placed upright against each other. The plates for instance have a height of 3
metres and a width of 6 metres. In order to be able to transport several plates simultaneously,
a number of separators are arranged for instance every 8 to 10 plates, so that an
interspace is created between each packet of glass plates. Known separators have a
thickness of approximately 25 mm. The known separators are usually made of plastic
or paper material in order to acquire sufficient strength at a low weight.
[0003] The separators are automatically fitted onto a glass plate after the latter has been
cut off, either prior to placing the plates upright or during or after it placing
them upright. So as to prevent the separators from sliding down, they are provided
at one end with a thickening, called nose in the field, which hooks behind the upper
edge or head end edge of the glass plate. In order to prevent that a separator shifts
or falls off the glass plate, for instance during manipulation of the glass plate,
the separator can be provided, at the side of the nose, with a detachable connecting
means, such as a suction cup.
[0004] It is known to use a separator, in which the nose consists of a substantially squared
angle section with a first sidepiece and a second sidepiece. The strip of carrier
material here is provided with a recess near the end where the nose has to be attached.
In this recess the first sidepiece of the nose is attached, so that the second sidepiece
of the nose projects at the level of the end of the strip of carrier material. Such
a separator according to the preamble of claim 1 is known from the International patent
application W097/12817.
[0005] A drawback of this known separator is that a recess has to be made in the strip of
carrier material. Another drawback is that the nose, which is also made from plastic
or paper material, has a rounding-off in the inner angle which is present between
the first sidepiece and the second sidepiece. As a result the separator will not lie
on the head end edges of the glass plates with the second sidepiece when the first
sidepiece abuts the glass plates, or the separator will remain at a distance from
the glass plates when the second sidepiece rests on the head end edges of the glass
plates. Another drawback is that the nose will have to be treated to ensure that it
does not leave particles, such as paper particles, on the glass, as the first sidepiece
will come to rest against the flat side of a glass plate.
[0006] It is an object of the invention to provide an improved separator. It is another
object to provide a simplified separator. It is yet another object to provide a separator
which can be made at low costs.
[0007] At least one of these objects if achieved with the separator according to claim 1.
[0008] In this way it is achieved that when used the first sidepiece projects upright beyond
the glass plate. The first sidepiece need no longer be arranged recessed in the layer
of carrier material. It is also achieved in this way that the first sidepiece no longer
contacts the glass plates, so that only the second sidepiece will come to rest on
the head end sides or edges of the glass plates. As it will not be so bad when a particle
such as a paper particle will end up on the head end edges of the glass plates, the
second sidepiece will not have to be treated against the leaving of particles, so
that in fact the entire nose need not have such a treatment. When the nose is made
from paper material, it can be recycled better in this way.
[0009] Now that the nose, with regard to the known separator, is as it were turned around,
the rounding-off between the sidepieces will no longer contact the glass plates and
the second sidepiece will always abut the head end edges of the glass plates well.
It also surprisingly appeared that the attachment is better resistant to the loads
to which the nose of the separator is subjected, in particular the shearing loads.
From tests it appeared that the resistance to shearing loads can be twice as high
as with the known separator.
[0010] According to an advantageous embodiment the first sidepiece is arranged on the strip
of carrier material in line with the contact plane of the strip of carrier material
with the plates. In this way a recess in the strip of carrier material is no longer
present.
[0011] Preferably the edge of the first sidepiece, which faces away from the second sidepiece,
is arranged at the same level as the end of the strip of carrier material. In this
way the separator projects beyond the glass plates as little as possible.
[0012] In an advantageous manner the first sidepiece is glued to the strip of carrier material,
preferably by hotmelt glue.
[0013] Preferably the angle section is substantially as wide as the strip of carrier material,
so that the angle section can be made as thin as possible.
[0014] According to an advantageous embodiment the angle section is made from paper material,
preferably from solid cardboard. With a carrier from paper material the entire separator
can be recycled, and with solid cardboard the sidepieces of the angle section can
remain thin.
[0015] Preferably the angle section consists of layers of paper that are laminated to each
other, which in a preferred embodiment is recycled photographic paper. In this way
the angle section acquires great strength, in which the photographic paper offers
a cheap basic material.
[0016] Preferably the strip of carrier material consists of a strip of honeycomb panel,
particularly cellulose material, such as paper or cardboard. Honeycomb panel is a
very light and rigid material, to which the nose can easily be glued.
[0017] Preferably the second sidepiece of the angle section projects 10 to 40 mm beyond
the carrier material, depending on the thickness of the packet of (glass) plates.
[0018] The invention will be elucidated on the basis of an exemplary embodiment, referring
to the attached drawing.
[0019] Figure 1 shows a perspective view of the separator according to the invention.
[0020] Figure 2 shows a side view of the separator according to figure 1 on a slightly smaller
scale.
[0021] Figure 3 shows a perspective view of the nose of the separator according to figure
1 on a larger scale.
[0022] Figure 1 shows the separator 1 consisting of an elongated strip of honeycomb panel
2 which at its upper end is provided with a nose which is formed by an angle section
3 from solid cardboard.
[0023] Figure 3 shows that the angle section 3 consists of a first sidepiece 4 and a second
sidepiece 5.
[0024] Figure 2 shows, that near the upper end of the strip of honeycomb panel 2 the first
sidepiece 4 of the angle section 3 is arranged on the honeycomb panel, the first sidepiece
4 extending upwards with regard to the second sidepiece 5.
[0025] Figures 1 and 2 clearly show that only the second sidepiece 5 will come to rest against
the glass plates. The inner rounding-off 6 between the first sidepiece 4 and the second
sidepiece 5 will not contact the glass plates, because the first sidepiece 4 extends
upwards with regard to the second sidepiece 5.
[0026] The angle section 3 preferably is as wide as the strip of honeycomb panel 2 is wide.
In the exemplary embodiment the strip of honeycomb panel is more than 3 metres long,
80 mm wide and 20 mm thick.
[0027] When using an angle section, consisting of solid cardboard made from laminated recycled
photographic paper, the thickness of the sidepieces 4 and 5 need only be about 3 mm.
[0028] In order obtain sufficient adhesion, by means of a hotmelt glue, of the first sidepiece
4 to the strip of honeycomb panel 2 the first sidepiece 4 preferably is 60 mm high.
[0029] The second sidepiece 5 of the angle section 3 preferably projects 10 to 40 mm beyond
the strip of honeycomb panel 2.
