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.
1. A method for making an absorbent composite from a continuous tow comprising the steps of:
spreading a crimped tow;
de-registering the crimped tow;
shaping the de-registered tow; and
distributing a particulate onto the shaped tow wherein particulate distribution being controlled by a vibratory particulate feeder coupled to a trough, and a plate and the trough defining a shaped orifice.
2. The method of claim 1 wherein the shaped orifice being rectangular.
3. The method of claim 1 wherein the shaped orifice being triangular.
4. The method of claim 1 wherein the shaped orifice being serrated or toothed.
5. The method of claim 1 further comprising shaping the de-registered tow to a substantially rectangular cross-section.
6. The method of claim 1 further comprising applying a liquid to the tow.
7. An apparatus for making an absorbent composite from a continuous tow comprising the steps of:
means for spreading a crimped tow;
means for de-registering the crimped tow;
means for shaping the de-registered tow; and
means for distributing a particulate onto the shaped tow wherein particulate distribution being controlled by a vibratory particulate feeder coupled to a trough, and a plate and the trough defining a shaped orifice.
8. The apparatus of claim 7 wherein the shaped orifice being rectangular.
9. The apparatus of claim 7 wherein the shaped orifice being triangular.
10. The apparatus of claim 7 wherein the shaped orifice being serrated or toothed.
11. The apparatus of claim 7 further comprising means for shaping the de-registered tow to a substantially rectangular cross-section.
12. The apparatus of claim 7 further comprising means for applying a liquid to the tow.
