Abstract
Apparatus for dispensing a material, such as by meltblowing, wherein the apparatus provides a flow of air in a first direction and a flow of material in a second direction at an angle with respect to the first direction, and wherein the air flow contacts the material flow and propels the material in a direction substantially parallel to the first direction of the air flow for deposition on a desired substrate.
Claims20
An applicator head for depositing a material upon a surface, comprising:
- a deposition material die body comprising a spray outlet for discharging deposition material out from said deposition material die body and toward said surface onto which said deposition material is to be deposited;
- an air manifold assembly for conducting a flow of air toward said spray outlet;
- and a material dispensing assembly, having a surface thereof disposed opposite a surface of said air manifold assembly and along a substantially planar interface defined therebetween, for conducting a flow of material toward said spray outlet;
- first flow path means defined within said material dispensing assembly of said deposition material die body for conducting a flow of said material in sheet form along a first direction within said deposition material die body and toward an impact position which is located along said substantially planar interface and adjacent to said spray outlet;
- second flow path means, defined within said material dispensing assembly and fluidically connected to said first flow path means, for conducting said material from said air manifold assembly to said first flow path means;
- third flow path means defined within said air manifold assembly and fluidically connected to said second flow path means of said material dispensing assembly for conducting a supply of said material from a source of said material, through said air manifold assembly, toward said material dispensing assembly, across said substantially planar interface along which said material dispensing assembly and said air manifold assembly are oppositely disposed, and into said second flow path means of said material dispensing assembly;
- and
- fourth flow path means defined within said air manifold assembly for conducting a flow of air in sheet form and along a second direction, within said deposition material die body, which is disposed at a predetermined angle with respect to said first direction of said flow of material so as to contact said material flow with said air flow at said impact position located adjacent to said spray outlet, break up said sheet of material into fine particles, and propel said fine particles of said material, in a direction which is substantially parallel to said second direction of said air flow and along with said air flow, toward and onto said surface as said deposition material.

An applicator head for depositing a substantially viscous material onto a substrate, comprising:
- a deposition material die body comprising a spray outlet for discharging deposition material out from said deposition material die body and toward said substrate onto which said deposition material is to be deposited;
- an air manifold assembly for conducting a flow of air toward said spray outlet;
- and a material dispensing assembly, having a surface thereof disposed opposite a surface of said air manifold assembly and along a substantially planar interface defined therebetween, for conducting a flow of said substantially viscous material toward said spray outlet;
- said material dispensing assembly comprising first flow path means for conducting a flow of said substantially viscous material in sheet form along a first direction within said deposition material die body and toward an impact position which is located along said substantially planar interface and adjacent to said spray outlet, and second flow path means, fluidically connected to said first flow path means, for conducting said substantially viscous material from said air manifold assembly to said first flow path means;
- and
- said air manifold assembly comprising first flow path means fluidically connected to said second flow path means of said material dispensing assembly for conducting a supply of said substantially viscous material from a source of said substantially viscous material, through said air manifold assembly, toward said material dispensing assembly, across said substantially planar interface along which said material dispensing assembly and said air manifold assembly are oppositely disposed, and into said second flow path means of said material dispensing assembly;
- and second flow path means for conducting a flow of said air in sheet form and along a second direction, within said deposition material die body, which is disposed at a predetermined angle with respect to said first direction of said flow of substantially viscous material so as to contact said substantially viscous material flow with said air flow at said impact position located adjacent to said spray outlet, break up said sheet of substantially viscous material into fine particles, and propel said fine particles of said substantially viscous material, in a direction which is substantially parallel to said second direction of said air flow and along with said air flow, toward and onto said substrate as said deposition material.
