Abstract (en)
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. <IMAGE>
