Abstract
The present invention provides a method and apparatus for drilling a plurality of holes in a stretched substrate in at least two directions not in the same plane, including providing a substrate in a substrate holder, stretching the substrate in at least one direction to a stretched configuration, and drilling at least one hole in the substrate while in a stretched configuration. The present invention further provides methods and apparatus for drilling impinging jet nozzles in stretched or pre-stretched substrates.
Claims14
A method of drilling a plurality of holes in a stretched substrate, comprising:
- providing a substrate in a substrate holder;
- stretching the substrate in a first direction and in a second direction wherein the first direction and second direction are in different planes to obtain a stretched configuration;
- and
- drilling a plurality of holes in the substrate while the substrate is in the stretched configuration.
An apparatus for providing an aerosol from a fluid, the apparatus comprising:
- a substrate produced by stretching the substrate in a first direction and in a second direction wherein the first direction and second direction are in different planes to obtain a stretched configuration;
- drilling a plurality of holes in the substrate while the substrate is in the stretched configuration;
- and
- a reservoir for holding the fluid.
A method of forming an aerosol from a liquid, comprising:
- providing a substrate produced by stretching the substrate in a first direction and in a second direction wherein the first direction and second direction are in different planes to obtain a stretched configuration;
- drilling a plurality of holes in the substrate while the substrate is in the stretched configuration;
- and
- forcing the fluid through the substrate to make an aerosol.
