Molded fiber product production line utilizing fluid trim operation
A molded fiber part former includes a first forming mold defining a first mold area and at least one fluid inlet. The molded fiber part former also includes a wall substantially surrounding the first mold area. The molded fiber part former includes a fluid channel disposed adjacent to and surrounding the wall, wherein the channel is fluidically connected to the at least one fluid inlet and defines a fluid channel outlet.
1. A molded fiber part former comprising:
a first forming mold defining a first mold area and at least one fluid inlet;
a wall substantially surrounding the first mold area; and
a fluid channel disposed adjacent to and surrounding the wall, wherein the fluid channel is fluidically connected to the at least one fluid inlet and has a fluid channel outlet having a fluid slot, and wherein the fluid slot is configured to eject a substantially annular stream of fluid.
2. The molded fiber part former of claim 1 , further comprising:
a sealing ring at least partially covering the fluid channel outlet, wherein the sealing ring is spaced apart from the wall so as to at least partially define the fluid slot therebetween.
3. The molded fiber part former of claim 2 , wherein the sealing ring is fixed to the first forming mold.
4. The molded fiber part former of claim 2 , wherein the sealing ring is removably fixed to the first forming mold.
5. The molded fiber part former of claim 1 , wherein the fluid channel defines a maximum channel width and the fluid slot defines a maximum slot width less than the maximum channel width.
6. The molded fiber part former of claim 1 , wherein the fluid slot is disposed so as to direct the substantially annular stream of fluid in a direction substantially orthogonal to an uppermost extent of the wall.
7. The molded fiber part former of claim 1 , further comprising a second forming mold defining a mating mold area configured to mate with the first mold area of the first forming mold.
8. The molded fiber part former of claim 7 , wherein the second forming mold comprises an outer rim surrounding the mating mold area, and wherein when the first mold area and the mating mold area are in a mating configuration, the outer rim is configured to deflect the substantially annular stream of fluid in a direction away from the first mold area and the mating mold area.
9. The molded fiber part former of claim 8 , wherein the outer rim is curved.
10. The molded fiber part former of claim 1 , wherein the at least one fluid inlet comprises a plurality of fluid inlets.
11. The molded fiber part former of claim 10 , wherein the plurality of fluid inlets are distributed about an outer edge of the first forming mold.
12. The molded fiber part former of claim 10 , wherein the plurality of fluid inlets are each fluidically connected to the fluid channel.
