Machine and method for hair or bristle removal
View Patent ↗Devices and methods for removal of animal hair are provided. The devices and methods can include one or more rotating bodies that form pinch regions for mechanical removal of animal hair.
1. A device for removal of hair or bristles from an animal, comprising:
a first cylindrical body having a longitudinal axis;
a second cylindrical body having a longitudinal axis, wherein the first cylindrical body and second cylindrical body are positioned proximate to one another and can rotate about their respective longitudinal axes; and
a third cylindrical body having a diameter that is less than a diameter of each of the first and second cylindrical bodies and is positioned between the first and second cylindrical bodies;
at least one flexible sheet of material wrapped about a portion of the first cylindrical body in a first direction relative to the longitudinal axes of the cylindrical bodies and also wrapped about a portion of the second cylindrical body in a second direction opposite the first direction such that as the first cylindrical body and the second cylindrical body rotate about their longitudinal axes, an elongated pinch point is formed between the flexible sheet and the second cylindrical body.
2. The device of claim 1 , wherein the second cylindrical body comprises a surface including teeth.
3. The device of claim 1 , wherein the second cylindrical body comprises a textured surface.
4. The device of claim 1 , wherein the flexible sheet comprises a surface including teeth.
5. The device of claim 1 , wherein the wherein the flexible sheet comprises a textured surface.
6. The device of claim 1 , wherein the third cylindrical body comprises a surface including teeth.
7. The device of claim 1 , wherein the third cylindrical body comprises a textured surface.
8. The device of claim 1 , further comprising at least two additional cylindrical bodies, each in contact with the flexible sheet and capable of rotating about their longitudinal axes.
9. The device of claim 8 , wherein the at least two additional cylindrical bodies have an adjustable position with respect to the first and second cylindrical bodies.
10. The device of claim 1 , further including a rod member positioned proximate the elongated pinch point and extending substantially parallel to the longitudinal axes of the first and second cylindrical bodies.
11. The device of claim 10 , wherein the rod member includes a cylindrical rod.
12. The device of claim 11 , wherein the cylindrical rod has a longitudinal axis about which the cylindrical rod can rotate.
13. The device of claim 11 , wherein the rod member is operatively engaged with a spring member configured to bias the rod member towards the elongated pinch point.
14. The device of claim 1 , wherein the at least one additional cylindrical body includes at least two cylindrical bodies, each in contact with the flexible sheet and capable of rotating clockwise about their longitudinal axis.
15. The device of claim 1 , further including a power source operatively connected to at least one of the cylindrical bodies to rotate the cylindrical bodies about their longitudinal axes.
16. The device of claim 15 , wherein the power source is configured to rotate the cylindrical bodies and produce a torque sufficient to generate at least 20 pounds per inch along the elongated pinch point.
17. The device of claim 1 , wherein the at least one flexible sheet of material comprises multiple flexible sheets of material positioned proximate one another.
18. The device of claim 1 , wherein the flexible sheet contacts the surface of the second cylindrical body over at least 120° of a circumference of the second cylindrical body.
19. The device of claim 1 , wherein the flexible sheet forms a continuous loop around the third cylindrical body and at least one additional cylindrical body.
