Customizable apparatus and method for transporting and depositing fluids

摘要

A system for depositing a fluid on a substrate is disclosed. The system can include a sleeve having a sleeve exit and an inner region and a rotating roll disposed within the inner region. A vascular network can be disposed within the rotating roll, the vascular network being configured for transporting the fluid in predetermined paths from the interior region to the exterior surface through a substantially radial path, the substantially radial path ending at an exit point of a fluid exit, wherein the exit point is associated with a sleeve exit.

1. A system for depositing a fluid on a substrate, the system comprising:
a rotating roll having an exterior surface and a sleeve substantially surrounding a portion of the exterior surface to form a sleeve coverage area and having a sleeve exit, wherein:
the rotating roll comprises a central longitudinal axis and rotates about the central longitudinal axis;the exterior surface substantially surrounds the central longitudinal axis and defines an interior region;a vascular network is disposed within the interior region, the vascular network being configured for transporting the fluid in a predetermined path from the interior region to the exterior surface and comprising a main artery, a plurality of capillaries and a plurality of fluid exits disposed on the exterior surface, wherein:
the main artery comprises an inlet and is substantially parallel to the central longitudinal axis of the rotating roll, wherein the fluid enters the vascular network at the inlet;each capillary is associated with the main artery and in fluid communication with the main artery and at least two fluid exits through substantially radial paths to form a tree;the sleeve exit is associated with an exit point of at least one of the fluid exits; andone of the fluid exits is disposed outside of the sleeve coverage area.
