Method and device for producing an annular multiaxial laid fabric and an annular object produced therewith

A method for producing an annular multiaxial laid fabric, which is constructed from at least two thread layers laid one on top of the other, the method comprising the following steps:

• a. Laying of a lower thread layer in the form of an endless thread array or an endless single thread, or in the form of thread-array sections or single-thread sections, around the entire circumference of two mutually spaced ring elements, the thread array or the single thread, or the thread-array sections or the single-thread sections, of the lower thread layer being held temporarily, after laying, by thread-holding elements arranged around the ring circumference, and the threads of the thread array or the thread-array sections or the single thread or the single-thread sections of the lower thread layer forming an angle (α) within the range greater than 0 degrees up to 90 degrees to the circumferential direction of the ring elements,
• b. Laying of a upper thread layer in the form of an endless thread array or an endless single thread, or in the form of thread-array sections or single-thread sections, around the entire circumference of the two mutually spaced ring elements, the thread array or the single thread, or the thread-array sections or the single-thread sections, of the upper thread layer being held temporarily, after laying, by the thread-holding elements arranged around the ring circumference, and the threads of the thread array or the single thread, or the thread-array sections or the single-thread sections, of the upper thread layer forming an angle (β) greater than 0 degrees to the threads of the thread array or the single thread, or the thread-array sections or the single-thread sections, of the lower thread layer,
• c. Fixing the threads of the thread array or the single thread, or the thread-array sections or the single-thread sections, of the lower thread layer at points to the threads of the thread array or the single thread, or the thread-array sections or the single-thread sections, of the upper thread layer by means of a fixing unit around the circumference of the first and upper thread layers laid in a ring,
• d. Detaching the first and upper thread layers from the thread-holding elements, and
• e. Removing the annular multiaxial laid fabric from the mutually spaced ring elements.
