Abstract

Example implementations relate to shafts with blades with tapered surfaces consistent with the disclosure. For example, a device including a shaft, a blade with a plurality of tapered surfaces, the surfaces tapered from a center of the shaft to an outer edge of the shaft, and a membrane attached to the plurality of tapered surfaces to facilitate print substance transport from the center of a print substance container towards the edges of the print substance container.

First claim

What is claimed:

1. A device comprising:
a shaft;
a blade with a plurality of tapered surfaces, the surfaces tapered from a center of the shaft to an outer edge of the shaft; and
a membrane attached to the plurality of tapered surfaces to facilitate print substance transport from the center of a print substance container towards the edges of the print substance container.

2. The device of claim 1 , further comprising the blade mounted on the shaft.

3. The device of claim 1 , wherein the shaft further comprises:
a solid surface portion; and
a cored portion.

4. The device of claim 1 , further comprising the membrane mechanically attached to the plurality of tapered surfaces.

5. The device of claim 1 , wherein the membrane is shaped to be received by the plurality of the tapered surfaces of the blade.

6. The device of claim 1 , the shaft further comprising two extended portions at each end of the shaft to couple to the print substance container.

7. The device of claim 1 , further comprising the blade to couple to the shaft in response to receiving heat.

8. A system comprising:
a first print substance container;
a second print substance container; and
a shaft comprising a blade with a plurality of tapered surfaces to:
rotate print substance in the first print substance container; and
transport the print substance to the second print substance container.

9. The system of claim 8 , further comprising the plurality of tapered surfaces being tapered from a center of the shaft to an outer edge of the shaft.

10. The system of claim 8 , wherein the first print substance container includes a first channel and a second channel to transport print substance from the first print substance container to the second print substance container.

11. The system of claim 10 , further comprising a laser beam between the first channel and the second channel.

12. The system of claim 8 , wherein the first print substance container is coupled to the second print substance container.

13. A method comprising:
activating a shaft located in a first print substance container with a plurality of channels, wherein the shaft includes a blade with a plurality of tapered surfaces;
rotating the shaft to stir print substance in the first print substance container;
moving the tapered surfaces of the blade at an angle towards edges of the first print substance container to transport print substance to the plurality of channels of the first print substance container; and
transporting print substance from the plurality of channels of the first print substance container to a second print substance container.

14. The method of claim 13 , further comprising transporting print substance from the first print substance container to the second print substance container via the plurality of channels to shield a laser beam, wherein the laser beam shines on a site between the first print substance container and the second print substance container to facilitate printing images on a print material.

15. The method of claim 13 , further comprising the blade attaching to the shaft responsive to the shaft stirring the print substance to facilitate transporting the print substance to the plurality of channels of the first print substance container.
