Definitions
- the present invention relates to a method for Manufacture of blanks from composite materials after the Preamble of claim 1.
- Another problem is that manufacturing of individual cuts with punching knives is extremely time-consuming and is therefore expensive.
- the object of the present invention is therefore therein a method of making blanks from To create composites with the relatively inexpensive and can be worked according to the pattern.
- This task is accomplished through a manufacturing process of blanks made of composite materials, which by the Features of claim 1 is characterized.
- the main advantage of the method according to the invention is that it is made possible for the first time from composite materials, which are arranged in several layers one above the other are cuts on a computer-controlled cutter system, especially for motor vehicle seats. This allows you to perform the same cutting operation much more cuts from the multilayer composite materials arranged one above the other become. Care is taken to ensure that the individual cuts with regard to their patterns in almost identical in a way not previously possible to match. This advantage is particularly important because composites with patterns in the automotive industry are used more and more. At a Cutting surgery can be done according to the inventive method a variety of pattern pieces at the same time and can therefore be manufactured extremely inexpensively.
- Suitable cutter systems are known for example from DE 31 36 445 A.
- the composite layers usually consist of a surface layer 4 provided with a pattern is, a foam layer 5 and a side layer 6, which is a sliding on the cushioning material Motor vehicle seat should allow.
- the patterns own for example the shape of checks or stripes, along and / or across the material web, as well as from others geometric figures and signs.
- the surface layer 4 preferably consists of a textile material, Leather or plastic.
- the layers mentioned are in the given order linked together, in particular bonded.
- FIG Designated 20 A needle table known per se is shown in FIG Designated 20.
- This needle table essentially exists 20 from an upper worktop 21, in the openings 25 are provided, and a movable lower plate 26 arranged parallel to the upper worktop 21 and with the in the openings 25 of the worktop 21st guided needles 2 are firmly connected. Furthermore, the Needle table 20 on a mechanism 24, with the help upon rotation of a crank 22 and a shaft 23 in one way or the other the lower plate 26 so is moved that the needles 2 more or less far emerge from the openings 25.
- the pattern the first composite layer in a predetermined Way is aligned to the needles 2.
- the first layer of composite material because of the always present arch-shaped Pattern warp drawn or stretched accordingly.
- the described Process the needles 2 in a certain way Pattern of the first layer of composite aligned. following are the other composite layers in a corresponding manner to the underlying composite layer by exact alignment to the needles 2 arranged, the needles gradually by moving the lower plate 26 can be extended further. The sample the composite layers are then exactly to each other aligned.
- top composite layer a cover sheet 3 arranged, its function will be explained later.
- a composite stack 10 for example according to FIG 3 from five composite layers and a cover film 3 exists in which the individual composite layers are accurate are arranged one above the other.
- the number of composite layers can according to the respective requirements vary.
- It consists essentially of a plate-shaped Part 41, from which individual needles 42 to protrude one side of the plate-shaped part 41, wherein the length of the needles 42 corresponding to that to be fixed Stack 10 is preferably larger than the respective stack height.
- the composite stack 10 thus fixed is then together with the pincushions 40 arranged in it the vacuum worktop 31 of a known cutter system 30 transferred. 2 are the For the sake of simplicity, that in the vacuum worktop 31 arranged openings through which the vacuum is generated is not shown.
- the side edges of the stack 10 are made with the help sealed by adhesive films 50 such that below of the stack 10, a vacuum can be generated.
- the pincushion 40 are out the compacted stack 10 'removed.
