Abstract
A method of making an insert for a substantially solid cylindrical article that is constructed from a highly elastic material and braided fiber forming a mesh of very specific geometry, which supports any application that requires protection from cutting, puncture or similar damage while preserving high deformability of the article, particularly radial compressibility and/or axial elongation.
Claims22
A method of making an insert for a substantially solid cylindrical article, the method comprising the steps of:
- extruding a core of silicone material;
- wrapping fibers to form a braided fiber mesh on the extruded core;
- forming an overcoat layer of silicone material over the braided fiber and core to form a core-braid-overcoat product;
- heat-curing the core-braid-overcoat product;
- and
- cutting the core-braid-overcoat product to produce the insert.
A method of making a nipple portion for a bite-safe artificial teat, the method comprising the steps of:
- forming an insert by;
- extruding a core of silicone material;
- wrapping fibers to form a braided fiber mesh tube on the extruded core;
- forming an overcoat layer of silicone material over the braided fiber mesh tube and core;
- heat-curing the core-braid-overcoat product;
- and
- cutting the core-braid-overcoat product to produce the insert;
- providing a mold comprising:
- a first mold part containing an interior cavity to form the substantially solid cylindrical article;
- a second mold part to close the first mold part;
- and
- a sprue extending from an outer surface of either the first mold part or the second mold part to the interior cavity of the first mold part;
- placing the insert into the interior cavity of the first mold part;
- closing the first mold part and the second mold part;
- and
- injecting silicone material into the mold via the sprue.
A method for forming a cylindrical article including the steps of:
- providing a cylindrical silicone elastomeric material having a hardness in the range of Shore A 1 to Shore A 25;
- and
- imbuing the elastomeric material with a mesh to protect against biting or other damage;
- wherein the properties of the silicone material are not degraded when the silicone elastomeric material and mesh is stretched.
