Abstract:
Device and method for producing a unidirectional (UD) layer from a predetermined number of filament strands. Device includes a dispenser arrangement structured and arranged for delivering the predetermined number of filament strands, and a storage arrangement, structured and arranged for temporary storage of the predetermined number of filament strands. The storage arrangement includes separate storage parts for each of the predetermined number of filament strands. Device also includes a spreading arrangement and an outlet.
Abstract:
Device and method for spreading a carbon fiber hank into a carbon fiber band. The device includes a heating device having at least two electrodes that are spaced apart from each other and coupled to a power supply, and a spreading device arranged after the heating device in the traveling direction of the carbon fiber hank.
Abstract:
A device for feeding fiber bands to a knitting machine, wherein the device includes a creel having at least one bobbin with at least one fiber band. Further, at least one feed drive driving at least one feeder roll, such that the fiber band is guided by the at least one feeder roll. Further still, a band storage including a motor driven control drive arranged to change the length of a variable length storage path for the at least one fiber band, wherein the band storage is arranged between the creel and the at least one feeder roll. A control device actuates the motor driven control drive and the at least one feed drive in a manner coordinated with one another.

Abstract:
Method and device for producing a unidirectional (UD) layer with a predetermined layer width from a predetermined number of filament strands. The method includes spreading the filament strands out transversely to a longitudinal direction of the UD layer to form bands that are arranged next to one another. A first width of the bands is greater than a dividing width, which corresponds to the predetermined layer width divided by the predetermined number of filament strands.

Abstract:
An apparatus for supplying a multi-layer, multiaxial yarn stratum to the knitting site of a warp knitting machine, with endless conveyor chains for guiding the yarn stratum to the knitting site, with at least two multiple yarn guides, which can be moved changeably over both conveyor chains for each yarn sheet and with means for supporting the yarn stratum. The prelaid yarn stratum is supplied in such a manner, that at least one endless conveyor belt is driven synchronously with the conveyor chains and supports the yarn stratum, and is guided over guide rollers mounted on the frame with the distance between the guide roller and the knitting site bridged with the help of supporting guiding elements for the yarn stratum.
