Definitions

  • the invention relates to a separator for sheets, in parti ⁇ cular fragile sheets such as glass sheets, comprising a strip of support material with a thickening or nose at one end.
  • Suchlike separators are used in the glass sheet industry.
  • the glass leaves the glass melting furnace as a continuous web, which is cut into sheets, after which the sheets are placed upright against each other.
  • the sheets have, for example, a height of 3 metres and a width of 6 metres.
  • a number of separators are fitted for example every 8 to 10 sheets, so that an interspace is created between each packet of glass sheets.
  • Known separators have a thickness of approximately 25 mm.
  • the known separators are usually made of plastic or paper material so as to acquire sufficient strength at a low weight.
  • the separators are automatically laid on a glass sheet after the latter has been cut off, either prior to placing the sheet upright or during or after upright placing.
  • they are provided on one end with a thickening, called a nose in the technical field, which hooks behind the upper edge of the glass sheet.
  • a nose in the technical field, which hooks behind the upper edge of the glass sheet.
  • the separator can be furnished with a detachable connecting means such as a suction cup.
  • a strip of honeycomb panel for the strip of support material is known, as this is a light material which is rigid and which can easily take up forces perpendicular to the surfaces of its cover layers.
  • honeycomb layer In a direction parallel to the cover layers a honeycomb layer is not strong, however, which is a reason for not using the honeycomb panel as a nose for a separator: the weight of the separa ⁇ tor brings about shearing forces in the nose, which the nose - if the latter were made of common honeycomb sheet - cannot absorb.
  • this object is achieved with a separator of the kind described in the introduction, in which the nose is made of one piece of honeycomb sheet, which is formed undivided into a nose having a thickness of at least twice the thickness of the honeycomb sheet .
  • the piece of honeycomb sheet is indeed shaped into a nose with at least double thickness, but is not divided, at least one of the cover layers of the piece of honeycomb sheet is kept intact. This cover layer holds the honey ⁇ comb-shaped parts of the nose together, so that it is strong enough to resist shearing forces occurring during use.
  • the piece of honeycomb sheet from which the nose is made turned over at least twice over substantially 90°, so that at each bend the outer cover layer can be continued so as to give the nose the desired strength.
  • the piece of honeycomb sheet is bent over twice at the location of two parallel V-shaped grooves arranged in the piece of honey ⁇ comb sheet.
  • the grooves can be made in a known way by cutting out or pressing in.
  • V-shaped grooves are arranged such that the two portions on both sides of the grooves abut each other after manufacture of the nose, so that the nose is twice as thick as the piece of honeycomb sheet from which it is made, and the cover layers of both abutting portions can be attached to each other.
  • the nose is arranged in such a way to the strip of support material that when in use the portion of the honeycomb sheet between the two bends comes into contact with the glass sheets, so that the continuous cover layer comes into contact with the (glass) sheets and can prevent damage of the honeycomb core material of the nose.
  • the nose is arran ⁇ ged such on the strip of support material that the portion between the V-shaped grooves in the piece of honeycomb sheet is facing away from the end of the strip of support material to which the nose is attached.
  • the continuous cover layer of the portion between the V-shaped grooves will, when in use, rest on the edges of the (glass) sheet, whereby the shearing forces are transferred in the most advantageous way to the strip of support material and paper and glue remainders on the honeycomb material resulting from cutting will not come into contact with the sheets.
  • the nose is made by glueing the piece of honeycomb sheet, preferably with the help of a hot melt adhesive, so that a stiff nose is formed, all portions of which being easily attached to one another.
  • the strip of support material is a strip of honeycomb panel, to which the nose is attached by glueing, preferably with the help of a hot melt adhesive . Because of this the whole separator is made of honeycomb panel, which facilitates production, and the whole separator can be recycled.
  • the nose With the help of a hot melt adhesive the nose can be manufactured and attached to the strip of honeycomb sheet at considerable speed.
  • Fig. 1 shows a perspective view of a separator according to the invention
  • Fig. 2 shows a side view of the separator according to fig. 1 on a reduced scale.
  • Fig. 3 shows a side view of the nose of the separator according to the invention on an enlarged scale.
  • Fig. 4 shows a side view of the piece of honeycomb sheet from which the nose according to fig. 3 has been made.
  • a separator usually has a length of 2 - 3.35 m, a width of 60 - 120 mm and a thickness of 20 - 60 mm.
  • the compression strength is of primary importance: this is approximately 350 - 400 kPa.
  • the separator therein con ⁇ sists of three layers, of which the central layer forms a honeycomb structure and the two outer layers, which con ⁇ tact the glass, are made of paper of which the acidity level is neutral.
  • the central, honeycomb-shaped layer is composed of strips of paper, folded and glued together in such a way, that a structure is created which consists of a large series of interconnected walls which enclose similar prismatic hexagonal spaces.
  • the walls of these hexagonal spaces are positioned upright between the two above-mentioned outer layers (cover layers) and are con- nected thereto by means of the glue in such a manner that shearing forces (in the plane) can be transferred onto the opposite cover layer. In this manner a rigid and light prismatic beam is created with a high compression strength.
  • the hexagonal spaces or cells therein usually have an inner diameter of 10 to 30 mm.
  • the paper which is used for the hexagonal spaces therein has a mass of 150 - 300 g/m J and the paper wich is used for the cover layers has a mass of 150 - 750 g/m 2 .
  • the glue which is used to compose such a honeycomb panel can be an or ⁇ dinary, commercially available glue which is suitable for paper.
  • the paper which is used is of a similar quality as the paper used for the manufacture of corrugated board and can consist in part or entirely of recycled old paper and/or in part of entirely of paper of cellulose fibres.
  • honeycomb panel material can be used for the nose.
  • Figure 1 shows a separator 1 consisting of a strip of honeycomb panel 2 and a nose 3.
  • the nose 3 is made of a piece of honeycomb sheet with the same thickness as the strip of honeycomb panel 2.
  • Fig. 3 shows the nose 3 in side view at approximately O 97/12818
  • the nose 3 consists of two side portions 4, 6 and a triangular shaped intermediate portions 5 which connects with the side portions 4,6.
  • the side portions 4 and 6 are glued to each other with their cover layers 7.
  • the cover layers 8, 9, 10 form one continuous layer of paper or cardboard.
  • Fig. 4 shows the piece of honeycomb sheet 3 from which the nose has been constructed.
  • the sheet 3 two V-shaped grooves 13 have been arranged, which have an apex angle of 90° and which extend parallel to one another. With their apex the grooves 13 reach up to the cover layer 7. By folding the side portions 4 and 6 towards each other, the nose 3 is thus formed.
  • the V-shaped grooves 13 can have been formed by cutting away the honeycomb panel in the grooves 13 (as shown) , but the grooves 13 are preferably formed by making incisions 12 represented by dashed lines, and then pushing the honeycomb material in the grooves 13 down and/or to the side.
  • the paper or cardboard of the upper cover layer 7 will thus form a part of the sides of the V-shaped grooves 13, so that these parts too can be glued together when forming the nose 3.
  • the V-shaped grooves 13 extend to the lower cover layer 8, 9, 10 so that the piece of honeycomb panel 3 does not fall into three separate pieces, but the lower cover layer 8, 9, 10 continues uninterruptedly and is only folded when making the nose 3 , as a result of which this cover layer 8, 9, 10 affords great strength.
  • the separator 1 is 3 meters or more long, 80 mm wide and 20 mm thick.
  • the nose 3 is 45 mm high, 40 mm thick and also 80 mm wide.
  • the cover layer 9 of the triangular-shaped intermediate portion 5 faces away from the end of the strip of honeycomb sheet 2, so that this cover layer portion 9 comes to rest on the glass sheets when the separator is used.
  • the shearing forces caused by the weight of the separator are thus led through via the shortest route to the strip of honeycomb panel 2, whereby the nose 3 only has to be of limited height.
