    摘要: A process and apparatus for spreading fibers in a fibrous tow provides a fiber spreader for spreading a tow of fibers moving in a machine direction having a plurality of spaced pins, where the spacing between the pins is variable relative to the machine direction, and the position of the pins is variable relative to the machine direction. Variation of the spacing and position of the pins during motion of the pins contact with a tow moving generally in the machine direction provides a spread tow of lower, more uniform areal weight for further use in product applications. Variation in pin spacing and fiber spreading results from rotation of at least one pin relative to another after the pins are inserted into a tow. Alternate techniques for fiber spreading and additional features for stress relief of fibers during the fiber spreading operation are disclosed.

    摘要: The invention provides an air opening jet for use in a process for making a rectangular structure made from a tow of fibers, such air opening jet including a housing, an air jet for moving the tow through the housing and opening the tow, and an accumulating chamber that includes at least one, and preferably two, perforated plates located in the path of the moving tow, and an air control arrangement for controlling the flow of air so that the moving tow is urged into engagement with the perforated plates to retard movement of the tow and cause it to properly accumulate in the accumulation chamber. The invention also includes methods for using the air opening jet apparatus to produce multi-tow band products, and products produced by such methods.
