Definitions

  • the invention relates to a method for producing a webbing with two identical, real selvedges and a webbing produced by this method.
  • a further disadvantage of all known belt straps, in particular belt straps for seat belts, is that, in particular, a one-time overstretching of the belt strap is not readily recognizable subsequently, so that there is a risk that an already overstretched belt strap continues is used, although it can no longer meet the requirements due to the previous overstretching.
  • the object of the invention is therefore to improve a webbing, which can also be used as a safety belt in transport, provided with two genuine identical selvedges, and a method for its production in such a way that equally beautiful round edges are achieved on both sides with economical production and the greatest possible protection of the material and a warping of the band during weaving and in particular in the course of a subsequent heat treatment is largely avoided, and, if necessary, an indication for a one-time exceeding of a predetermined, permissible elongation is achieved.
  • This object is achieved essentially in that with two opposing weft insertion needles and at least two shed weaving both for each of the edges and for the center of the band, and if necessary, two closing threads are woven in a symmetrical arrangement, each of the two edges using one of the two Weft insertion needles are woven, and that in addition an insert consisting of at least one warp thread and influencing the optical appearance of the webbing is woven into the webbing.
  • the inventive method avoids the different Reference to the two edges, especially those on the outer warp or. Edging threads acting weft tension.
  • the two edges of the webbing are either woven as hollow edges or respectively woven as single-layered edges and closed by means of a closing thread to form the hollow edge.
  • the invention also provides variable arrangements of the insert influencing the optical appearance of the belt strap, in that such a can be arranged in at least one, but preferably in each of the two edges of the webbing, a preferred embodiment further providing that an insert influencing the visual appearance of the webbing lies in at least one, but preferably in each of the two, edges formed as hollow edges is arranged.
  • the insert for changing the visual appearance of the webbing changes its appearance depending on its condition, for example a previous stretch.
  • the insert consists of only one warp thread, and that the insert consisting of at least one warp thread in its longitudinal center or, depending on the force course occurring during its intended use within the belt, also off-center in the middle part of the Arranged webbing and for the insert comprising at least one warp thread, a thread made of a non-load-bearing material, which is less elastic than the material of the load-bearing regions of the belt webbing and, if required, also has strength, is used.
  • the insert consisting of at least one warp thread is arranged so as to partially step towards the belt surface by means of appropriate control, in particular running in one of the shed.
  • a thread with a color of the material of the supporting regions of the belt webbing of different colors is used for the insert comprising at least one warp thread.
  • the symmetrical design is further supplemented by the fact that, at the same time, a separate closing thread for each of the two edges is optionally also woven with auxiliary threads and the stitch row of the auxiliary thread (s) is moved along the edges of the central part after the hollow edges forming the fold, which also has the further advantage is that with preferred use of a thin auxiliary thread along both edges of the webbing, the stitch row formed by the auxiliary thread also disappears in the fabric, the closing threads having the task of closing the edge parts.
  • At least two weaving compartments and a central compartment with an unchangeable, but also variable height position, in which the insert is guided, can be formed for each of the two hollow edges, the weft thread in each case by means of one of the two weft insertion needles through the Fan only one of two edges of the webbing is worn.
  • the insert can also perform other tasks, so with a suitable choice of material and / or color, the insert can also form an indicator that a predetermined permissible elongation of the webbing has already been reached or exceeded once is.
  • the material of the insert expediently has an elongation or tensile strength which is generally less than that of the warp threads, which is the case in the production of belt straps made of homogeneous material, as is preferred in particular in the case of seat belts, which are to be made entirely of a polyester material, can be achieved in that the material of the insert is pre-stretched or pre-stretched or otherwise pretreated or simply has corresponding technical data.
  • the seat belt has other tasks than when a seat belt is used as the sole restraint. While a seat belt provided as the sole restraint is intended to connect the vehicle occupant as rigidly and rigidly as possible to the vehicle body in the event of a sudden and strong vehicle deceleration, this is no longer necessary and also undesirable when additional restraint means, in particular airbags, are used. In this case, in the event of a sudden strong vehicle deceleration, the seat belt is to reduce part of the restraining forces to be exerted on the vehicle body against the vehicle body by taking up work, for which purpose it must undergo permanent stretching.
  • the belt of the seat belt must have a certain elasticity, which no longer exists with a belt that has already been stretched beyond a certain limit can be.
  • An eye-catching display for a stretching of the belt strap that has already occurred beyond a permissible, possibly low, dimension therefore appears to be highly desirable, in particular for seat belts.
  • the insert consists of a different, for example, a higher load-bearing material than the material of the main part of the belt.
  • the invention therefore also provides in a further embodiment that an insert made of a material that is different from the material of the main part of the webbing strap with regard to its elongation or tensile strength, e.g. there is slightly different material and possibly also inserted into the middle part of the belt, whereby on the one hand the desired indicator function is ensured and increased by different colors and on the other hand an emergency stop function of a technical belt can be achieved.
  • the middle part of the belt webbing is woven with the formation of two weaving compartments by means of the two weft insertion needles working oppositely in superimposed planes.
  • the two edges which are to be blown in a symmetrical configuration and arrangement adjacent to the central part of the webbing, are each woven as edges, each forming two looms, each of the two edges being woven using only one of the two weft insertion needles and only one of the two weft threads. It can also be seen that a closing thread is used for each of the two edges of the webbing to be designed as hollow edges.
  • a non-load-bearing insert which influences the optical appearance of the belt webbing and consists of warp threads, is installed in the edges of the belt webbing, while, according to the representation B, a non-symmetrical woven webbing belt load-bearing insert, also consisting of warp threads, influencing the optical appearance of the belt strap, especially after a single exceeding of a predetermined stretch, built-in insert in the middle part of the belt strap.
