  • Patent number: 11453976
    Abstract: An impregnation system and a method for impregnating a textile fabric for composite components are described. A matrix 2 can be applied to a textile fabric 1 in such a way that the matrix 2 penetrates it at least partially and/or at least on one side. A first and a second endless belt 1 each designed as a belt loop are provided for the impregnation system. Between the first 4 and the second belt loop 5, the textile fabric 1 can guided on the mutually facing surfaces 6 of the belt loops and can be impregnated there. The deflection rollers 7 are provided in the respective belt loop 4, 5 of the respective endless belts at the deflection areas, with at least one roller being adjustable in the direction of the mutually facing surfaces 6 of the belt loops 4, 5. By adjusting the rollers 8 in the y direction, the wrap angle and thus the pressure exerted on the textile fabric during impregnation is controlled.

  • Patent number: 10876224
    Abstract: A device and method for spreading a fibre bundle spread, the fibre bundle being from a fibre bundle supply to a fibre take-up by way of a resistance device, having a first impulse drive that interacts with the resistance device, the fibre take-up being disposed downstream of the resistance device. The fibre bundle by means of the impulse drive during spreading is superimposed in an alternating manner in predefined sequences with an additional speed component in the conveying direction of the fibre bundle and/or with an additional speed component counter to the conveying direction.
