Abstract
A method of attaching an end seal (20) to a manufactured seed (22). The method including the steps of positioning a first manufactured seed on a surface (42). The first manufactured seed including a seed coat (24) having an opening (12) and an embryo (30) disposed within the opening. The opening having a location relative to the surface. The method further including prestressing an area (38) of a sheet (50) and positioning the sheet on the first manufactured seed to substantially center the area over the opening, such that the embryo is located below the area. The method also including the step of attaching the sheet to the first manufactured seed to seal the opening.
Claims29
A method of attaching an end seal to a manufactured seed, the method comprising the steps of:
- (a) positioning a manufactured seed on a tray, the manufactured seed including a seed coat having an opening and an embryo disposed within the opening, the opening having a location relative to the tray;
- (b) positioning a sheet between first and second templates, each template having a bore extending therethrough to expose a predetermined area of the sheet;
- (c) prestressing the predetermined area of the sheet;
- (d) positioning the sheet on the manufactured seed to substantially center the predetermined area over the opening such that the embryo is located below the predetermined area;
- and
- (e) attaching the sheet to the manufactured seed to seal the opening.
A method of attaching an end seal to a manufactured seed, the method comprising the steps of:
- (a) positioning a first manufactured seed on a surface, the first manufactured seed including a seed coat having an opening and an embryo disposed within the opening, the opening having a location relative to the surface;
- (b) prestressing an area of a sheet;
- (c) positioning the sheet on the first manufactured seed to substantially center the area over the opening such that the embryo is located below the area;
- (d) attaching the sheet to the first manufactured seed to seal the opening;
- (e) placing the sheet between a first template and the first manufactured seed before prestressing an area of the sheet, the first template having a bore extending therethrough;
- and
- (f) placing a second template between the sheet and the first manufactured seed such that the sheet is sandwiched between the first and second templates, the second template having a bore extending therethrough.
A method of attaching an end seal to a manufactured seed, the method comprising the steps of:
- (a) positioning a manufactured seed on a surface, the manufactured seed including a seed coat having an opening and an embryo disposed within the opening, the opening having a location relative to the surface;
- (b) ablating a predetermined area of a sheet;
- (c) positioning the sheet on the manufactured seed to substantially center the predetermined area over the opening such that the embryo is located below the predetermined area;
- (d) attaching the sheet to the first manufactured seed to seal the opening;
- (e) forming a dimple in the predetermined area of the sheet before ablating the predetermined area;
- and
- (f) placing the sheet between first and second templates before ablating the predetermined area of the sheet, the first and second templates each having a bore extending therethrough.
A manufactured seed, comprising:
- (a) a seed coat having a length and a cavity extending from one end of the seed coat partially through the length of the seed coat, the cavity having an open end and a closed end;
- (b) an embryo disposed within the cavity;
- and
- (c) an end seal attached to the one end of the seed coat, the end seal having at least one a prestressed area, the prestressed area being located on a predetermined portion of the end seal to position the prestressed area substantially over the opening of the cavity, wherein the prestressed area includes an annular collar formed in at least one surface of the sheet, wherein the annular collar is at least partially received within the cavity to form a seal between the end seal and the cavity.
