A method and apparatus for making an absorbent composite from continuous tow is disclosed. The method and apparatus includes the steps of or means for spreading a crimped tow; de-registering the crimped tow; shaping the de-registered tow to a substantially rectangular cross-section; and distributing a particulate onto the shaped tow. The step of or means for spreading the tow uses at least two banding jets.

Method and apparatus for making an absorbent composite

A method and apparatus for making an absorbent composite from continuous tow is disclosed. The method and apparatus includes the steps of or means for spreading a crimped tow; de-registering the crimped tow; shaping the de-registered tow to a substantially rectangular cross-section; and distributing a particulate onto the shaped tow. The step of or means for distributing the particulate is controlled through a shaped orifice.

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.
