System and method for textile positioning

A circular needle loom comprises a stationary bed plate for receiving a spiral textile. Engagement members may be disposed next to the stationary bed plate, such that the engagement members interface with a positional structure of the spiral textile that is used to position and rotate the spiral textile around the stationary bed plate. A conical roller deploys the spiral textile on the stationary bed plate. The engagement members rotate the spiral textile around the stationary bed plate until a predetermined number of layers are deposited on the stationary bed plate.A spiral textile comprises a weft tow that extends from an inside diameter to an outside diameter, and a positional structure, such as a sacrificial edge and / or loop, is located next to and / or is attached to the weft tow. The positional structure facilitates positioning the spiral textile in a desired manner with respect to the circular needle loom in order to create a needled preform.

Beam winding apparatus

An apparatus and method for winding a sheet of aligned parallel yarns onto a beam is described. The beam winder utilizes a circularly arced yarn spool rack that feeds each yarn to an alignment comb through associated guide tubes. The distance between each spool of yarn and the alignment comb is substantially the same for all spools of yarn, thereby equalizing the force necessary to pull them to the comb. Next, the aligned sheet of material is preshrunk using heated rollers and wound onto a beam. Multiple speed controlled stepper motors are utilized to maintain a constant low level of tension in the sheet during the shrinking process. After shrinkage, the tension level of the yarn sheet is increased as it is wrapped onto the beam. A turntable that supports two or more beams is provided to facilitate the rapid switching of beams once one beam has become full.
