Abstract

An apparatus and method for modifying an aspect of an exterior polymer material or polymer type material of a linear substrate with a fluid. The apparatus include a variable exposure gap within which the linear substrate is exposed to the fluid. The width of the exposure gap is varied with the speed of the linear substrate traversing the exposure gap to maintain a constant exposure time of the linear substrate with the modifying fluid.

First claim

What is claimed is:

1 . A method for modifying an aspect of a linear substrate, the method comprising:
providing a processing barrel comprising an outer wall having opposing ends and a chamber defined therein, the processing barrel further comprising a linear substrate inlet into the chamber and a linear substrate outlet out of the chamber, wherein the linear substrate inlet and the linear substrate outlet are coupled to the wall and moveably connected with respect to each other; defining an exposure gap between the linear substrate inlet and the linear substrate outlet; and configuring a length of the exposure gap to greater than zero, wherein configuring the length of the exposure gap comprises moving one of the linear substrate inlet and the linear substrate outlet to one of a plurality of relative positions, wherein each of the plurality of relative positions define a different length of the exposure gap.

2 . The method of claim 1 , wherein configuring the length of the exposure gap comprises moving one of the linear substrate inlet and the linear substrate outlet to a first relative position of the plurality of relative positions, wherein in the first relative position, one of the linear substrate inlet and the linear substrate outlet is located between the opposing ends of the wall and the exposure gap having a first length that is greater than zero, and wherein in the first relative position the exposure gap is in fluid communication with the chamber.

3 . The method of claim 2 , wherein configuring the length of the exposure gap comprises moving one of the linear substrate inlet and the linear substrate outlet to a second relative position of the plurality of relative positions, wherein in the second relative position, one of the linear substrate inlet and linear substrate outlet is in a second relative position that is different from the first relative position, and wherein in the second relative position the exposure gap has a second length that is different from the first length.

4 . The method of claim 2 , wherein configuring the length of the exposure gap comprises moving one of the linear substrate inlet and the linear substrate outlet to a second relative position of the plurality of relative positions, wherein in the second relative position the exposure gap has a second length that is less than 50% of the first length.

5 . The method of claim 1 , wherein an exposure of an exterior polymer material or a polymer type material of the linear substrate varies with a speed of the linear substrate.

6 . The method of claim 1 , wherein the linear substrate inlet and the linear substrate outlet comprise seals.

7 . The method of claim 1 , the processing barrel further including a fluid inlet and a fluid outlet in fluid communication with the chamber, and wherein the compartment is configured such that, relative to one another, the fluid inlet is positioned toward one end of the processing barrel and the fluid outlet is positioned toward the other end of the processing barrel.

8 . The method of claim 1 , wherein the processing barrel further comprises an inner processing vessel and an outer processing vessel, the outer wall being part of the outer processing vessel, the inner processing vessel and the outer processing vessel forming a nested arrangement along a longitudinal length of the processing barrel with at least a portion of the chamber defined therebetween, the inner processing vessel being axially moveable relative the outer processing vessel.

9 . The method of claim 8 , wherein the linear substrate inlet includes an infeed seal having a central bore configured to allow the linear substrate to pass into the processing barrel while substantially retaining fluid within the processing barrel.

10 . A method for modifying an aspect of a linear substrate, the method comprising:
providing a processing barrel comprising an outer processing vessel and an inner processing vessel, the outer processing vessel comprising an outer wall having opposing ends, the inner processing vessel and the outer processing vessel forming a nested arrangement along a longitudinal length of the processing barrel with at least a portion of a chamber defined therebetween, the inner processing vessel being axially moveable relative the outer processing vessel, the processing barrel further comprising a linear substrate inlet comprising an inlet seal and defining an inlet opening into the chamber and a linear substrate outlet comprising an outlet seal and defining an outlet opening out of the chamber; defining an exposure gap between the linear substrate inlet and the linear substrate outlet, configuring a length of the exposure gap to greater than zero, wherein configuring the length of the exposure gap comprises moving one of the inlet seal and the outlet seal to one of a plurality of relative positions, wherein each of the plurality of relative positions define a different length of the exposure gap.

11 . The method of claim 10 , wherein the processing barrel further comprises a liquid inlet and a liquid outlet in liquid communication with the chamber.

12 . The method of claim 10 , wherein the at least one of the inlet seal and the outlet seal is moveably coupled to the outer wall and is moveable with respect to the other of the inlet seal and the outlet seal between the plurality of relative positions.

13 . The method of claim 10 , wherein in a first relative position, the one of the inlet seal and the outlet seal being located between the opposing ends of the outer wall and the exposure gap having a first length that is greater than zero, in the first relative position the exposure gap also being in liquid communication with the chamber.

14 . The method of claim 13 , wherein in a second relative position of the inlet seal and the outlet seal the exposure gap having a second length that is less than the first length.

15 . The method of claim 10 , wherein the inlet seal has an inner diameter configured to allow a linear substrate to pass into the processing barrel while substantially retaining infusion liquid within the processing barrel.

16 . A method for modifying an aspect of a linear substrate, the method comprising:
providing a processing barrel comprising an outer processing vessel and an inner processing vessel, the outer processing vessel comprising an outer wall having opposing ends, the inner processing vessel and the outer processing vessel forming a nested arrangement along a longitudinal length of the processing barrel with at least a portion of a chamber defined therebetween, the processing barrel also having a linear substrate inlet having an inlet seal and defining an inlet opening into the chamber and also a linear substrate outlet with an outlet seal and defining an outlet out of the chamber, defining an exposure gap between the linear substrate inlet and the linear substrate outlet, wherein at least one of the inlet seal and outlet seal being moveably coupled to the outer wall and being moveable with respect to each other between a plurality of relative positions, each of the relative positions defining a different length of the exposure gap; and configuring a length of the exposure gap to greater than zero, wherein configuring the length of the exposure gap comprises moving at least one of the inlet seal and outlet seal in a first relative position, wherein in the first position, the one of the inlet seal and outlet seal being in a first position located between the opposing ends of the outer wall
