Abstract

An apparatus includes a first belt having an external surface, a second belt having an external surface opposite the external surface of the first belt, and a region in which the first belt and the second belt come in contact, a first material dispenser and a second material dispenser to dispense a first material and a second material on the external surface at least one of the first and second belts, and a power source to cause at least one of the first and second belts to move to cause the external surfaces of the first and second belts to contact and then diverge away from each other so that at least one of the first and second materials forms filaments that break up as the belts continue to diverge.

First claim

What is claimed is:

1 . An apparatus, comprising:
a first belt having an external surface; a second belt having an external surface positioned opposite to the external surface of the first belt, with a region in which the first belt and the second belt come in contact; a first set of guide devices arranged inside the first belt; a second set of guide devices inside the second belt; a reactive first material; a first material dispenser containing the reactive first material positioned to allow the reactive first material to be dispensed on the external surface of the first belt; a second material reactive with the reactive first material, wherein the reactive first material causes the second material to change chemical composition when the reactive first material and the second material are mixed; a second material dispenser containing the second material positioned to allow the second material to be dispensed on the external surface of the second belt, wherein the region in which the first and second belts come in contact is of a length sufficient to cause mixing of the first and second materials to form a reactive system; a power source to cause at least one of the guide devices in at least one of the first set and the second set of guide devices to cause at least one of the first and second belts to move to cause the external surfaces of the first and second belts to contact and then diverge away from each other so that at least one of the reactive first material and the second material forms filaments that break up as the first and second belts continue to diverge; and a controller configured to control at least one of the belts to control an amount of time the first material and second material are mixed.

2 . The apparatus as claimed in claim 1 , wherein the controller is connected to at least one guide device of the first and second set of guide devices, the first material dispenser and the second material dispenser.

3 . The apparatus as claimed in claim 1 , wherein the first set of guide devices comprises a first set of rollers arranged linearly within the first belt and the second set of guide devices comprise a second set of rollers arranged linearly within the second belt in parallel with the first set of rollers.

4 . The apparatus as claimed in claim 1 , wherein the first set of guide devices and the second set of guide devices are offset from each other.

5 . The apparatus as claimed in claim 1 , wherein the first set of guide devices comprises a first set of rollers having two, three or four rollers and the second set of guide devices comprises a second set of rollers with a same number of rollers as the first set of rollers.

6 . The apparatus as claimed in claim 1 , wherein the first belt and the second belt comprise timing belts.

7 . The apparatus as claimed in claim 1 , wherein the first belt and the second belt have different textures, with one belt having a rougher texture than the other.

8 . The apparatus as claimed in claim 1 , wherein at least one of the first belt and the second belt is adjustable as to control a length of the region in which the first belt and the second belt come in contact.

9 . The apparatus as claimed in claim 1 , wherein at least one of the external surface of the first belt and the external surface of the second belt has a texture.

10 . The apparatus as claimed in claim 1 , wherein the first set of guide devices and the second set of guide devices are positioned such that when the first and second belts move, alternating regions of high and low pressure form.

11 . An apparatus, comprising:
a first belt having an external surface; a second belt having an external surface positioned opposite to the external surface of the first belt, with a region in which the first belt and the second belt come in contact; a first set of guide devices arranged inside the first belt; a second set of guide devices inside the second belt; a reactive first material; a first material dispenser containing the reactive first material positioned to allow the reactive first material to be dispensed on the external surface of the first belt; a second material reactive with the reactive first material, wherein the reactive first material causes the second material to cross-link when the reactive first material and the second material are mixed; a second material dispenser containing the second material positioned to allow the second material to be dispensed on the external surface of the second belt, wherein the region in which the first and second belts come in contact is of a length sufficient to cause mixing of the first and second materials to form a reactive system; a power source to cause at least one of the guide devices in at least one of the first set and the second set of guide devices to cause at least one of the first and second belts to move to cause the external surfaces of the first and second belts to contact and then diverge away from each other so that at least one of the reactive first material and the second material forms filaments that break up as the first and second belts continue to diverge; and a controller configured to control at least one of the belts to control an amount of time the first material and second material are mixed.
