  • the foam blade is preferably of foamed polystyrene and advantageously comprises a non-foamed outer layer comprising polymethyl methacrylate.
  • the recess preferably has a semicircular, rectangular or polygonal section.
  • the recesses of the first and second edges have an identical section, but this is not essential, insofar as the section of the blocking element is similarly adapted.
  • the blocking element may be a solid or hollow element or even a U-shaped open profile. In practice, the blocking element is dimensioned in such a way that it has no clearance inside the cavity.
  • the general section of the blocking element corresponds to that of the cavity, but the blocking element may additionally have protuberances or protrusions on its outer surface in contact with the foam so as to maintain it in the foam. In the case of a cylindrical locking element, its outer surface may also have the shape of a thread.
  • the blocking element in addition to its shape acts as a stiffener and as such is in a sufficiently rigid material in the application conditions to be able to impart sufficient rigidity to the assembly.
  • the blocking element is made of metal, preferably aluminum or stainless steel.
  • Other materials such as wood, plywood, plastics, ferrous and non-ferrous metals, composite materials such as glass fibers, carbon fibers, Kevlar®, polyetheretherketone (PEEK), cement, polymer cement or any other suitable material, may however be suitable for certain applications.
  • the blade may further comprise in the body of the foam one or more longitudinal channels parallel to said first and second edges. These channels can be used to further stiffen the blade or assembly by introducing additional stiffening bars.
  • the assembly method then optionally also comprises the step of introducing a stiffening bar into each of the longitudinal channels or some only depending on the rigidity requirements.
  • the stiffening bars may be of the same type (material, shape, etc.) as the blocking elements or of a different type.
  • the opposite outer (major) surfaces of the blades may be identical or different, both in terms of the color (uniform, streaks of different colors, for example imitating the wood), of the shape (plane or other), and / or ornamentation (relief, grain, streaks, etc.) so that the appearance of a blade varies depending on which side the user sees the assembly.
  • the first edge corresponds to the second by rotation symmetry about the central axis of the blade parallel to said first and second edges as mentioned above, it is possible to alternate the orientation of a blade relative to the adjacent blade to have a more varied appearance.
  • finishing or termination foam blades having only a first edge or a second edge with groove and tongue as described here on one side of the blade.
  • the opposite edge of these blades is then in the form of a straight-sectioned ridge, rounded or having any shape, not plug-in an edge of another blade.

  • the raw materials are preferably in the form of regular granules, having if possible the same size and the same form from one component to another. It will also be preferred that the apparent density be in a narrow range between the various components, so as not to cause premature disbanding.
  • the components thus measured are fed to the feed of a laminating extruder.
  • This extruder preferably comprises two screws, which can be co- or counter-rotating, self-cleaning or not.
  • the cylinder has several heating zones. The first part of the cylinder is heated at high temperature, in order to plasticize the solid components dosed to the feed, while mixing them to homogenize the whole.
  • pressurized gas is injected via an injection port drilled into the cylinder. The gas will be maintained in its condensed phase, in particular in a supercritical state in the case of CO 2 .
  • the mixing of the components and the gas is kneaded and pressurized in order to obtain a good homogeneity and an optimal dissolution of the gas in the melted mixture to obtain a single phase.
  • the subsequent zones of the cylinder are then progressively colder in order to maintain the pressure necessary for the solubilization of the gas.
  • the cooled mixture is optionally again homogenized, by passing through a static mixer which will divide the flow into several "channels" which will be crossed and redistributed, in order to make the temperature profile of a perpendicular section of the flow as flat as possible.
  • the homogeneous, single-phase mixture of the plasticized components and the gas then passes into the forming tool, consisting of a die guiding the flow to the desired foaming form.
  • the pressure drop that the mixture undergoes since the exit of the cylinder decreases constantly the pressure of the mixture; at a time this pressure drops below the critical threshold where the gas, previously solubilized, will supersaturate the mixture and gas bubbles will then arise, forming a second discrete phase.
  • the zone of formation of these primary bubbles should not happen too early, under penalty of causing a premoussage giving a deformed and unstable foam, with an unattractive surface.
  • the means of action on the place where this critical demixing step occurs are multiple: viscosity of the components, temperature of the tool, proportion of gas, form of the tool, flow of the extruder ..., all these parameters to be optimized for each foam blade profile to achieve.
  • the foam leaves the atmosphere, at high temperature, and expands freely.
  • the viscosity of the cell walls increases with the cooling and migration of the gas in the cells, until the cell structure is frozen. But this process takes time, and the shape of the foam is usually not stable immediately.
  • To control the dimensions of the foam it can be passed through a calibration system, by a motorized draw at the end of the extrusion line.
  • the calibrators possibly temperature controlled for a more effective control of the shape especially at the beginning when the foam is the hottest, gradually impose the foamed mass its final shape.
  • first and second opposite parallel edges with their section forming a groove-like profile and a tongue-like profile are formed, respectively, the latter comprising the recess along its length.
  • This secondary layer which must be compatible with the former to ensure good cohesion, may have the function of strengthening the mechanical properties, resistance to external conditions or aesthetic properties, thus forming a protective layer, finish and / or decoration.
  • the foam is generally drawn by a motorized stretching machine, single or double depending on the number of blades extruded in parallel.
  • the blade is then cut to length by a saw, ensuring a perfectly perpendicular cut.
  • the Fig. 1 shows a cross section through a first blade variant 1 according to the invention.
  • the blade 1 comprises a foam profile 5 with two major surfaces 3 and 4 connected by at least first and second edges 15 and 25.
  • the first edge 15 comprises a tongue 12, a groove 13 and a recess 14.
  • the second edge 25 includes a tongue 22, a groove 23 and a recess 24. These edges are designed to be complementary to each other except at the location of the recesses 14, 24.
  • the tongue 12 of a first edge 15 can be plugged into a groove 23 of a second identical blade (not shown in FIG. Fig. 1 )
  • the groove 13 of the first edge 15 can receive the tongue 22 of the second blade.
  • the two recesses 14, 24 (of semicircular sections) form a cavity (of circular section).
  • a bar 10 is then inserted into each cavity to block and secure the assembly of several blades 1.
  • the blades 11 at the ends of the assembly are so-called finishing blades or termination.
  • the edge without groove and tongue of this blade, and thus of the assembly is straight, but it could have any other form, for example rounded, etc.
  • the Fig. 3 shows a blade variant 1 similar to that of the Fig. 1 , except that the blade 1 of this figure further comprises two longitudinal channels (hollow) 6.
  • the assembly of (two) blades 1 according to the Fig. 3 as shown in Fig. 4 is done in a similar way to that of the Fig. 2 but the assembly can be further stiffened (if desired) by introducing one or more additional bars 7 into the channels 6, as needed.
