Definitions

  • the invention relates to a roller blind for a roller blind arrangement of a vehicle and a method for producing

  • the roller blind has a pull bow for actuating the roller blind.
  • a roller blind arrangement is known for example from EP 1 006 012 A2.
  • the roller blind arrangement of a vehicle is disclosed, the roller blind web being designed to be wound up or unwound along an extraction direction.
  • the roller blind has a roller blind fabric.
  • the roller blind fabric is, for example, a flexible element, especially a flexible textile
  • the roller blind fabric is, for example, network-like.

  • the functional element is by means of
  • the functional element is formed in particular from a plastic.

  • the additive manufacturing can also be called 3D printing or
  • the multiplicity of layers are applied one after the other, for example in strips, in order to form the functional element.
  • Layers allow different properties for the functional element. In particular, different colors, shapes, cross sections, profiles or geometries are possible. In addition, the functional element can be implemented in different degrees of hardness.
  • Roller blind only takes a few seconds to print.
  • a granulate can be used instead of filaments, which is considerably cheaper.
  • Keder lengths can be displayed in different programs. There is no need for special tools. In addition, due to the additive manufacturing, functional elements no longer have to be cut to length or purchased to the respective variant. This enables, for example, easier warehousing, improved variant management and a comparatively higher added value. Additive manufacturing contributes to effective and reliable manufacturing. Furthermore, a great deal of flexibility and simpler
  • the functional element can thus be manufactured precisely and inexpensively. This enables better mechanical properties, for example. This also results in an improved look of the
  • Functional elements The production of the functional element can be carried out quickly and mechanically. In contrast to conventional functional elements, which are manufactured using injection molding technology, for example, the manufacturing costs can be reduced. Tool costs are lower and tool manufacturing time can be reduced
  • Flexibility can be achieved, for example, when changing the external dimensions of a functional element.
  • the degrees of freedom in the design are increased because, for example, the required draft angles of the injection molding technology are eliminated. Damage to the roller blind fabric due to separating burrs is avoided.

  • the print head conveys what is preferably liquid or viscous production material on the roller blind fabric, for example in the form of a plastic cord, a plastic track or a plastic strip, each in several layers or layers, which then hardens.
  • the print head is coupled to a tank or material depot, for example by means of a hose connection.
  • a kind of storage container sits directly on or on top of it, like a funnel
  • Printhead For production, a raw material can be melted during the manufacturing process or it is already in a flowable state for the application.
  • the additive manufacturing of a functional element therefore enables a very simple and relatively mobile construction of a manufacturing system.
  • the manufacturing system can be used flexibly. There are no high investment costs for differently designed roller blinds.
  • roller blind web is designed for use in a roller blind arrangement mentioned at the beginning.
  • a roller blind arrangement typically also includes lateral guides for the roller blind and at least one winding shaft, onto which the roller blind can be wound or from which the roller blind can be unwound.
