Flexible belt having a planed seam and processes for making the same
A post treatment process of a seamed belt for providing a smooth surface and substantially eliminating protrusions by using a planing blade, and a seamed belt that has undergone the post treatment.
1. A process for post treatment of a seamed belt ( 38 ) comprising:
providing a seamed belt comprising a member having a seam extending from one parallel edge to the other parallel edge of the member, the seam having a seam region comprising an overlap of two opposite ends of the member, the ends thus forming an overlap layer and an underlap layer;
positioning the seamed belt on a round anvil such that an edge of the seam region lies on an apex of the round anvil;
contacting the edge of the seam region with a planing blade such that the planing blade is elevated with respect to an exposed surface of the underlap layer proximate the edge of the seam; and
removing material from the edge of the seam region with a continuous cut, wherein the resulting flexible belt has a smooth seam.
2. The process of claim 1 , wherein the seam is selected from the group consisting of a welded seam, an ultrasonically welded seam, a puzzle-cut seam and a taped seam.
3. The process of claim 1 , wherein the seamed belt is selected from the group consisting of a photoreceptor, an electroreceptor, and an intermediate image transfer belt.
4. The process of claim 1 being automated.
5. The process of claim 1 , wherein the planing blade is mounted on an automated linear slide.
6. The process of claim 1 , wherein an amount of the material to be removed is based on a diameter of the anvil and a penetration depth of the planing blade.
7. The process of claim 1 , wherein the seamed belt is held on the anvil by vacuum.
8. The process of claim 1 , wherein a vacuum attachment is coupled above the planing blade to collect the material being removed.
9. The process of claim 1 , wherein the member consists of a single layer of substantially homogeneous material.
10. The process of claim 1 , wherein the member comprises at least two different layers having at least different compositions or different properties.
11. A process for post treatment of an ultrasonically welded seamed belt comprising:
providing a seamed belt comprising a member having a welded seam extending from one parallel edge to the other parallel edge of the member, the welded seam having a seam region comprising an overlap of two opposite ends of the member, the ends thus forming an overlap layer and an underlap layer;
positioning the seamed belt on a round anvil such that an edge of the seam region lies on an apex of the anvil;
contacting the edge of the seam region with a planing blade such that the planing blade is elevated with respect to an exposed surface of the underlap layer proximate the edge of the seam region; and
removing material from the edge of the seam region with a continuous cut, wherein the resulting seamed belt has a smooth welded seam.
12. The process of claim 11 , wherein the seamed belt is selected from the group consisting of a photoreceptor, an electroreceptor, and an intermediate image transfer belt.
13. The process of claim 11 being automated.
14. The process of claim 11 , wherein the planing blade is mounted on an automated linear slide.
15. The process of claim 11 , wherein an amount of material to be removed is based on a diameter of the anvil and a penetration depth of the planing blade.
16. The process of claim 11 , wherein the flexible belt is held on the anvil by vacuum.
17. The process of claim 11 , wherein a vacuum attachment is coupled above the planing blade to collect the material being removed.
