Definitions

  • the invention relates to a method for producing a textile module representing a lateral guide band for a roller blind.
  • Textile modules are known from practice and are part of a roller blind of a shading arrangement that can be used in the area of a vehicle roof.
  • the textile module is used to guide the roller blind in lateral guide rails and is optimally adapted to the relevant guide rail in terms of material. With its inner edge, the textile module is connected to a central section of the roller blind, which in the closed position of the roller blind forms its visible surface.
  • the textile module comprises a strip of fabric which is provided with a band-like guide element along a longitudinal edge, which engages in a guide track of the guide rail in question and is designed as a so-called scroll spring that automatically winds up outside the guide rail to form a roll and thus forms the winding spring of the roller blind .
  • a textile module with a scroll spring has been produced in such a way that a finished, wound scroll spring piece is provided with the desired length, is inserted manually into a device and is automatically pulled out there. Then an adhesive film is applied to the scroll spring and fixed under the action of heat. A strip of fabric is then connected to the scroll spring via the adhesive film.
  • the gluing process can be temperature and / or pressure controlled.
  • the rolled-up scroll spring can be manually inserted into a device and automatically pulled out there, whereupon a liquid hot-melt adhesive is applied to the Scroll spring is distributed.
  • a strip of material is inserted into the device and pressed there over the liquid hot glue under the action of pressure and temperature with the scroll spring.
  • the invention is based on the object of creating an economical method, which ensures constant product quality, for the production of a textile module for a roller blind that represents a lateral guide band.
  • a method is proposed in which a roll spring semifinished product is produced from a metal strip and is then provided on a roll.
  • a roll spring semifinished product is produced from a metal strip and is then provided on a roll.
  • the roll spring semifinished product and a fabric strip semifinished product from a fabric strip roll are arranged with one another in the manner of an endless process, in particular glued to one another, in order to produce a textile module semifinished product.
  • this can then be further processed so that a textile module with the required length results.
  • the semi-finished roll spring product provided on the roll can have a length of up to 500 m or more.
  • the semifinished fabric strip which is provided as a roll of fabric strips, expediently has a corresponding length.
  • the textile module semifinished product which is also provided on a roll, for example, is cut and / or punched to form the textile module which comprises the fabric strip and the scroll spring.
  • This process step is expediently designed as a function of the specific application on the basis of a standardized semi-finished textile module. The trimming length and the punching process are therefore adapted to the specific application.
  • the method according to the invention makes it possible to design textile modules in which no defined end is designed for connection to a tension bow or the like. Rather, the textile modules can be turned or rewound in this way. Similar textile modules can therefore be used to connect to both sides of the central web of the roller blind. It is thus possible to manufacture the textile modules as identical parts in an assembly system. Only by punching is it defined on which side of the central track the textile module is to be attached. Thus a tension-free connection of the scroll spring to a tension bow of the
  • the scroll spring or the semi-finished scroll spring product can be relaxed for the production of a coupling tab in a tab area, that is, the spring behavior in the tab area is canceled.
  • the relaxation in the tab area takes place in particular by heating, stamping and / or bending.
  • the relaxation process can take place after the cutting of the textile module semi-finished product on the textile module or also before it Trimming in a defined section of the textile module semi-finished product can be carried out after or before the connection of the fabric strip semi-finished product and the roll spring semi-finished product.
  • the tab area thus preferably has an at least largely straight course in the longitudinal direction of the scroll spring.
  • the coupling lug In order to give the coupling lug the shape required for connection to the tension bow, the coupling lug can be punched before, after or during the relaxation process.

  • the textile module semifinished product is cooled after the connection, in particular after the gluing of the roll spring semifinished product and the fabric strip semifinished product.
  • the roll of material and the second roll of the semifinished scroll spring product have unwinding axes aligned parallel to one another when the semifinished fabric strip and the semifinished scroll spring product are unwound. This means that both the semi-finished fabric strip and the semi-finished scroll spring can be fed to the disposition process without any further diversion.
  • the metal strip initially provided for stretching is, for example, guided on one side over an edge in such a way that a defined deformation of the metal strip takes place and anisotropic mechanical properties are induced.
  • the edge does not have to be sharp, but can also have a defined radius of curvature.
  • a steel band is used as the metal band, which consists for example of a steel of the type X10CrNil8-8.
  • the metal strip is heated or stored in an oven before or in particular after the stretching.
  • the scroll spring In order to counteract forces which act in the transverse direction of the blind when used on a roller blind, the scroll spring preferably has a helical course. This course can be achieved if the metal strip or the scroll spring follows a helical winding track when heated. An additional force in the transverse direction of the scroll spring is thus impressed on the scroll spring. In addition, this measure ensures that the resulting semi-finished scroll spring product has a constant spring force over its entire length. After delivery or heating, however, the semi-finished roll spring is wound onto the second roll to form a true-track roll. During heating or storage in an oven, the scroll spring is therefore pulled apart or opened in this embodiment in the direction of the winding axis, so that it has a constant winding diameter over its entire length. This also ensures that the scroll spring has the correct spring force over its length.
