Definitions

  • the present invention relates to an openwork structure in expanded material and more particularly such a structure comprising at least one solid strip parallel to the direction of deployment, made of any suitable material such as metal, paper, synthetic material or fabric.
  • Such a structure has, however, in certain applications, such as for example in the production of filters, the drawback of requiring relatively large external dimensions for a given surface of expanded metal and therefore of filtering, due to the rolling of the lateral strips.
  • the present invention aims to overcome these drawbacks and has for this purpose an openwork structure of expanded material comprising at least one solid strip parallel to the direction of deployment, characterized in that said strip has, in the direction of deployment, a length less than that of the deployed part.
  • This structure may for example comprise a solid strip along each of its edges parallel to the direction of deployment.
  • the invention also relates to a filter characterized in that it comprises at least one structure as described above.
  • This filter can be of any known type in which an expanded metal structure is used for example, but the pleated nature of the structure according to the invention makes it possible to obtain a larger filtering surface for a shorter developed length.
  • the structure according to the invention can also be used in the production of heat exchangers or electrical resistances because of its large exchange surface with respect to its external dimensions.
  • the invention also relates to a method of producing an openwork structure of expanded material in which a sheet of this material is simultaneously split and stretched, characterized in that at least one full and unstretched strip is kept parallel to the stretching direction of the sheet.
  • a conventional machine for producing expanded metal comprising at least one knife forming a succession of teeth and hollows, said knife being arranged to move substantially perpendicular to the surface of the sheet.
  • the knife cooperating with a counter blade splits and simultaneously stretches the sheet. If the knife has a width less than that of the sheet and the latter extends beyond the knife from each of its sides, a structure is obtained whose central part is deployed while the two lateral strips are full.
  • the active face of the knife facing the sheet is inclined relative to the surface of this sheet.
  • the active face can for example be inclined by about 30 °.
  • said teeth have a progressively decreasing depth towards the end of the knife in order to limit the risks of tearing of the material at the junction between the solid area and the stretched area.
  • Figure 1 shows an openwork structure made of a sheet 1 whose central part 2 is deployed. The deployment of part 2 is carried out in the direction of arrow F1.
  • the sheet 1 comprises in known manner solid end zones 3 in the form of strips perpendicular to the direction F1 of deployment.
  • the sheet 1 also includes two solid lateral bands 4 parallel to the direction of the arrow FJ and having undergone no stretching during the deployment of the zone 2.
  • the strips 4 therefore have a length in the direction of the arrow F1 less than the developed length of the zone 2 in this same direction.
  • Such a structure such as that shown in FIG. 1 can be advantageously used in a filter because it has, for relatively small external dimensions, a large filtering surface due to the folds produced in zone 2.
  • the fact that it has solid areas around its periphery makes it possible to easily ensure peripheral sealing and assembly.
  • FIG. 2 shows another perforated structure according to the invention, also comprising solid lateral bands 4 parallel to the direction F1 of the deployment of the zone 2 and of length less than the length of the deployed zone 2.
  • the meshes of zone 2 are much larger than those of the structure of FIG. 1 and this results in folds whose amplitude d is greater.
  • the openwork structure of Figure 2 can be presented either as that of Figure 1 with four solid peripheral bands, or with only three bands or even with only two bands.
  • a structure comprising only the solid strips 4 can advantageously be used as an element of electrical resistance. It also has remarkable rigidity due to the presence of the folds.
  • FIG. 4 represents a tool capable of being used to produce the structures of FIGS. 1 and 2.
  • This tool is formed by a blade 5 in which are fixed fixing holes 6.
  • the blade 5 comprises a succession of teeth 7 and recesses 8.
  • the tool is arranged as shown in FIG. 7 with respect to a counter blade 9 along which a metal strip 10 advances step by step in the direction of arrow F2. At each step, the tool descends perpendicularly to the sheet 10 in the direction of arrow F3 so that its teeth split and simultaneously stretch the metal to form the meshes 11.
  • the blade moves laterally alternately on one side and the other.
  • the lower face 12 of the tool which is directed towards the sheet 10 and which comprises the teeth 7 and the recesses 8, makes an angle a with the surface of this sheet which can be. example be equal to 30 °.
  • the depth of the teeth gradually decreases towards the end of the knife.
