Definitions

  • the invention relates to a method for producing a covering or separating element made of cardboard or the like. With the features of the preamble of claim 1 and a covering or separating element made of cardboard or the like. With the features of the preamble of claim 3.
  • cover elements of the type described above it is often necessary for easy hanging and reinforcing an edge area by gluing Strips of material etc. to achieve the required effect.
  • the attachment of such strips of material outside of the compression molding process normally used for the production of such cover elements is labor-intensive and expensive, and there is also the disadvantage that no attractive visible edges can be produced.
  • covering elements Furthermore, it has been found to be unfavorable in the previously known covering and / or separating elements, hereinafter generally referred to collectively as “covering elements”, that foreign materials such as metal rails or the like are generally used for stiffening thin laminates for reasons of weight. must be used, which not only causes weight problems again, but also warps of the overall structure when the cover elements are exposed to temperature. So far, it has only been possible with great difficulty to build such cover elements with low weight as torsionally stiff as this the dimensional accuracy because of z. B. is desirable in the automotive field itself.
  • the invention has for its object to provide a method for the simple manufacture of such a covering and separating element, and to further develop the previously known covering or separating element with respect to a simpler fastening.
  • the one-piece covering or separating element according to the invention can be used for flat, flat or shaped workpieces.
  • a narrow, preferably 20 mm wide edge strip is prepared to be bendable by embossing a crease.
  • sections are formed, of which the one sections, namely those forming the edge reinforcement sections, are alternately bent by 180 ° under the back of the cover element and glued to it, while the other sections, which are to form the hanging tabs, are preferably 135 ° are bent backwards so that they protrude from the rear of the surface and the protruding part can engage in hook-like manner in corresponding protruding parts of the counterparts attached to the surface to be clad.
  • edge strip of the cover element as a carrier of the two parts alternately molded onto the bent edge strips, namely hook-in tabs on the one hand and edge reinforcement sections on the other hand, are continuously and completely preserved as a whole remains, this construction gives the front edge adjacent to the fastening device or attachment fastening great rigidity and holding force because the attachment tabs are kept unchanged in shape by the completely bent over-reinforced edge reinforcement sections and thus additionally stiffen the front edge.
  • a particular advantage of the one-piece attachment fastening according to the invention is that clips and other fastening elements are saved and that the insertion and removal of the paneling takes place very quickly due to the omission of many individual operating elements. This is not only when installing new z. B. automotive headliner, but also for repair work of considerable advantage, if lines or controls are hidden behind the cladding, since considerable relief and savings in working time can be achieved by using the fastening device according to the invention.
  • the flat covering or separating elements according to the invention can be made of cardboard, foams, fiber mats, structures made of organic or inorganic fibers or also flat plastics or the like.
  • the visible surfaces are usually clad with decorative papers, decorative foils or textiles that have to be glued on.
  • the manufacture of a one-piece suspension fastening is composed of a number of individual operations, which, however, according to the invention are preferably combined in a single compression molding operation. In this compression molding process, using pressure and heat, molding, embossing the grooves for bending, gluing the parts bent over by 180 ° on the back and laminating the visible surface with the surface material are integrated.
  • the fastening device according to the invention is not only labor intensive in use, but also in the manufacture.
  • numerous individual fastening parts, such as clips and the like, and their attachment become superfluous, there is not only an easy-to-use component, but also an inexpensive component.
  • the covering or separating element according to the invention in which only the same materials are used, so no foreign materials, such as. B. metal strips must be applied, has the advantage that an excellent connection rigidity and dimensional accuracy can be guaranteed with low weight without warping due to different expansion coefficients of the different materials to be obtained under temperature stresses.
  • By laying the edge strips on top of each other and the material of the actual cover element along the bending line results in a "plywood-like" reinforcement of the edge area due to the laminate structure achieved in this way.
  • this laminate structure is further increased by the fact that when the edge strip is folded in the bending area, laminate compaction takes place, since tensile and compressive stresses occur not only in the plane of the flat material normal to the bending line, but also compressive forces acting perpendicular to the plane of the surface which further compress the individual layers of the laminate.
  • the edge strip is bent over, the tensile and compressive stresses which occur further parallelize the fibers, chain molecules, etc. in the various material layers parallel to the surface and normal to the bending line, which causes a special edge stiffening in the sense of "hardening" the edge area.
  • the tensile and compressive stresses generated in the material plane cause a special hardening of the corresponding edge, for example when tempering glass panes.
  • a flat cover element 1 made of a fiber mat construction or the like, has an edge strip 2 with a width of approximately 20 mm, a groove 4 being formed on the rear side 3 of the cover element 1, which is at the bottom in FIG. 1 which defines the aforementioned width of the edge strip 2 of approximately 20 mm.
  • the groove 4 is embossed into the rear side 3 of the cover element 1.
  • the individual parts of the edge strip 2, as will be explained in more detail below, can be bent to different degrees in the bending direction 5 indicated by an arrow.
  • edge strip 2 to 5 show that the edge strip 2 is divided into a plurality of individual sections by corresponding indentations, of which parts forming hook-in tabs 6 are bent by approximately 135 ° to the rear side 3 of the cover element 1, while the regions in between are used as edge reinforcement sections 7 bent 180 ° to the rear 3 of the cover element 1 and glued to it.
  • edge reinforcement sections 7 bent 180 ° to the rear 3 of the cover element 1 and glued to it.
  • a fastening device which consists of a multiplicity of hook-shaped hook-in tabs 6 bent by 135 ° against the rear, the edge regions lying between the hook-in tabs 6 by the rear side 3 of the cover element 1, glued on edge reinforcement sections 7, not visible from V, are glued to the rear side 3 to a high edge rigidity.
  • the edge reinforcement sections 7 are bent over by 180 ° and glued to the rear side 3 of the cover element 1, while alternating between these, visible, which are only bent by 135 °, serving as hooks and standing in the room hanging tabs 6.
  • the fastening device is produced in such a way that all the necessary molding and gluing processes are carried out in a single compression molding process using pressure and heat.
