Abstract: A powder application apparatus for an at least partially meltable powder to be applied onto a feeding element for producing reinforcing elements comprises a powder container. In the area of an outlet of the powder container a template for defining a basic shape of a reinforcing element to be produced is provided. Further, a closing device for opening and closing the outlet is provided. For producing reinforcing elements having different stiffness, barrier elements in particular connected with the template are provided. The barrier elements reduce the powder supply to the feeding element such that a reinforcing element with areas of different material thickness are created. A method for producing such a reinforcing element.

Abstract: An apparatus for producing reinforcing elements for shoes, bags or orthopedic applications comprises a first powder application apparatus, at least one downstream first compounding device, another second powder application apparatus as well as a second compounding device. Such a modular structure allows for producing different types of reinforcing elements in a simple manner.
Abstract: A reinforcing element, suited in particular for shoes, bags or orthopedic applications, comprises a support layer, and a reinforcing layer. The support layer is formed such that it protrudes at least in parts laterally beyond the reinforcing layer to form an edge region. A method for producing such a reinforcing element.

Abstract: There is proposed a powder application device P for producing blanks of thermoplastically deformable semifinished products for use as reinforcement elements, starting from a powder mixture containing a meltable plastics powder, comprising a downwardly open powder container B and a perforated stencil L, arranged beneath the latter and spaced apart therefrom, having one or more hole cutouts, said device being characterized in that the powder container B is rigidly connected to the perforated stencil L and is vertically lowerable as far as an auxiliary support or a distance of at most 5 mm therefrom, and is closable at its lower end by means of a horizontal closing plate S having a thickness slightly less than the distance between the powder container B and the perforated stencil L, wherein the closing plate S is movable in a horizontal plane such that it alternately closes and reopens the lower end of the powder container B.

Abstract: The present invention relates to novel thermoplastic reinforcement materials, particularly for the shoe industry, and a method for the production thereof. The novel thermoplastic reinforcement materials are obtained by a preliminary production step of pre-agglomeration of plant fiber filler materials and thermoplastic hot-melt adhesives, so-called filler-plastic compounds, allowing filler material originating from very inexpensive, naturally occurring plant fibers of varying origins to be used, but in an amount up to 65% by weight, without losing the required material properties, such as strength under heat, good flexural rigidity, and surface adhesion.
