A method for horizontally splitting rolled-up web material in the sample thickness. A carbon fiber nonwoven is moved in relation to a knife structure in order to split off a layer or successively several layers from a roll web. The one layer or several layers are continuously removed in the form of a roll from the carbon fiber nonwoven after the splitting process.

An apparatus for through thickness reinforcement of a fibrous preform includes an actuating textile needle, a feeder spool configured to supply a veil cloth, and a take up spool. The feeder spool and take up spool can rotate to cause a portion of the veil cloth to translate such that a needled portion of the veil cloth is received by the take up spool and an unneedled portion of the veil cloth is provided for subsequent needling by the textile needle. In this manner, the veil cloth is only momentarily supplied to the fibrous preform for providing the through thickness fibers and removed from the fibrous preform before subsequent processing of the fibrous preform. The textile needle, feeder spool, and take up spool can be mounted to a common apparatus (e.g., a housing) such that the entire assembly is moveable together as a single unit.

In a rubber-coated fabric, a plurality of warp cords is included with a spacing d between, sides of adjacent warp cords, each of the warp cords being coated with a layer of rubber compound, A cut line may further be included that separates groups of the warp cords, each group having a predetermined number of the warp cords. The cut line, may be formed by between 2 and 6 adjacent cut line warp cords, wherein a distance dc, between any two sides of adjacent cut Hue warp cords may be no more than. 50% of d. The layer of rubber compound that coats- the rubber-coated fabric is thin enough to outline the cut line on a surface of the rubber-coated woven fabric.

In various embodiments, the present disclosure relates generally to a method for needling a spiral textile to create a needled preform, the method comprising receiving the spiral textile on a bed plate of a circular needle loom, engaging a positional structure of the spiral textile, rotating the spiral textile around the circular needle loom, depositing a predetermined number of layers of the spiral textile on the bed plate, and needling the spiral textile to create the needled preform. Moreover, the present disclosure also provides, in various embodiments, a method for creating a circular needled preform from a spiral textile, comprising attaching sacrificial fibers to at least one of the weft tow and the plurality of warp tows proximate at least one of the inside diameter and the outside diameter, and engaging the sacrificial fibers with an engagement mechanism on a circular needle loom.
