Estimating the term…
A first aspect of the present application relates to a method for producing sound-damping, sound-absorbing and/or insulating molded material. More specifically, the method according to the invention relates to a method for producing said molded materials, wherein the fibrous material is wound around at least two carriers and subsequently the wound blank thus obtained remains on the carriers so as to be permanently solidified in order to obtain the molded material according to the invention. A further aspect of the present application concerns the molded material thus obtained, in particular in the form of molded mats or molded objects. Said molded material can be used, in particular, in mufflers. Finally, the following application concerns a device for producing said molded materials from fibrous material.
A method for producing sound-damping, sound-absorbing or insulating molded material, said molded material comprising fiber material, wherein said method has the following steps:
A device for the manufacturing of solidified sound-damping, sound-absorbing and/or insulating molded material having at least two, if applicable displaceable, carriers which are spaced apart from one another, said carriers being rotatably arranged, if applicable as individual carriers or as a group of carriers, having a unit for winding a fiber material around the at least two carriers and having a unit for solidifying the wound blank which is produced from the fibrous material and presented on the carriers wherein the unit for solidifying the wound blank presented on the carriers is one for solidification by means of air entanglement, for stitching, linking, knotting or needling, in particular rotary needling, felting or crocheting.
