Abstract

To provide a manufacturing method and a manufacturing device for a peeling member capable of manufacturing the peeling member having less variation in quality and excellent durability for long-time use at a low cost with excellent productivity by a simple structure. The manufacturing method for the peeling member includes sticking a non-adhesive resin film. In sticking the non-adhesive resin film, a distal end edge 2b of a distal end portion 2a of a base material 2 is arranged at a side of an adhesive layer of a non-adhesive resin film 4 such that an end portion of the non-adhesive resin film 4 is protruded from the distal end edge 2b, and then the non-adhesive resin film 4 is stuck on both surfaces of the distal end portion 2a of a base material 2 to wrap the distal end edge 2b of the base material 2 by pressing a plurality rollers 21 to 25 sequentially onto the non-adhesive resin film 4 from an one side end portion toward an another side end portion in a longitudinal direction of the base material 2.

First claim

The invention claimed is:

1. A manufacturing method for a peeling member, the peeling member comprising a peeling sheet formed by a base material formed of a metal plate or a resin plate and a non-adhesive resin film stuck to the base material, the peeling member being configured to peel a paper from a fixing member of an electronic photographic device by making a distal end portion of the peeling sheet, which is an end portion of a long side of the peeling sheet at an upstream side in a paper passing direction, contact with or close to the fixing member, the manufacturing method for the peeling member comprising sticking the non-adhesive resin film, which has an adhesive layer on a surface at a side opposite to a paper passing side, to a distal end portion of the base material corresponding to the distal end portion of the peeling sheet,
wherein, in sticking the non-adhesive resin film, a distal end edge of the distal end portion of the base material is arranged at a side of the adhesive layer of the non-adhesive resin film such that the end portion of the non-adhesive resin film is protruded from the distal end edge, and then the non-adhesive resin film is stuck on both surfaces of the distal end portion of the base material to wrap the distal end edge of the base material by pressing a plurality of rollers sequentially onto the non-adhesive resin film from an one side end portion toward an another side end portion in a longitudinal direction of the base material;
the rollers are sequentially arranged along a moving direction of the rollers moved relatively to the base material by a moving unit.

2. The manufacturing method for the peeling member according to claim 1 , wherein, in sticking the non-adhesive resin film, first to fifth rollers provided as the rollers are sequentially used to perform that (1) the first roller folds the non-adhesive resin film at an angle equal to or more than 10° and less than 50° against a surface of the base material, (2) the second roller folds the non-adhesive resin film at an angle equal to or more than 50° and less than 85° against the surface of the base material, (3) the third roller folds the non-adhesive resin film at an angle equal to or more than 100° and less than 165° against the surface of the base material to wrap the distal end edge of the base material, and (4) the fourth roller and the fifth roller interpose the distal end portion of the base material between them so that the non-adhesive resin film is stuck on the both surfaces of the distal end portion of the base material.

3. The manufacturing method for the peeling member according to claim 1 , wherein each of the rollers comprises a roller body and a roller shaft that supports the roller body in a rolling manner, and the roller body is formed of a rubber material, a foaming material, or a resin material.

4. The manufacturing method for the peeling member according to claim 3 , wherein the hardness of the roller body is set in a range between the Shore A10 hardness and the Shore A90 hardness.

5. A manufacturing device for a peeling member, the peeling member comprising a peeling sheet formed by a base material formed of a metal plate or a resin plate and a non-adhesive resin film stuck to the base material, the peeling member being configured to peel a paper from a fixing member of an electronic photographic device by making a distal end portion of the peeling sheet, which is an end portion of a long side of the peeling sheet at an upstream side in a paper passing direction, contact with or close to the fixing member, the manufacturing device comprising a film sticking unit that sticks the non-adhesive resin film, which includes an adhesive layer on a surface at a side opposite to a paper passing side, to a distal end portion of the base material corresponding to the distal end portion of the peeling sheet,
wherein:
the film sticking unit comprises a plurality of rollers and a moving unit that moves the rollers relatively to the base material;
the moving unit is configured to move the rollers relatively to the base material, which has the non-adhesive resin film stuck on one surface of the base material via an adhesive layer such that an end portion of the non-adhesive resin film is protruded from a distal end edge of the distal end portion of the base material, from an one side end portion toward an another side end portion in a longitudinal direction of the base material;
the rollers are sequentially arranged along a moving direction of the rollers moved by the moving unit, and the rollers comprises a plurality of the rollers for folding arranged to be inclined such that angles of surfaces of the rollers against the one surface of the base material are set to be gradually larger from an upstream side in the moving direction and a pair of the rollers for finishing arranged to interpose the base material from both surface sides and to follow a plurality of the rollers for folding; and
the manufacturing device for the peeling member is configured to use the moving unit to stick the non-adhesive resin film on both surfaces of the distal end portion of the base material to wrap a distal end edge of the base material by pressing the rollers for folding sequentially onto the non-adhesive resin film and interposing the base material from both surface sides by the rollers for finishing.

6. The manufacturing device for the peeling member according to claim 5 , wherein:
the film sticking unit comprises first to third rollers as the rollers for folding, and fourth and fifth rollers as the rollers for finishing; and
in a section orthogonal to the moving direction of the rollers moved by the moving unit, the first roller is inclined at an angle equal to or more than 10° and less than 50°, the second roller is inclined at an angle equal to or more than 50° and less than 85°, and the third roller is inclined at an angle equal to or more than 100° and less than 165° against the one surface of the base material, and the fourth and fifth rollers are parallel to the surface of the base material.

7. The manufacturing device for the peeling member according to claim 5 , wherein each of the rollers comprises a roller body and a roller shaft that supports the roller body in a rolling manner, and the roller body is formed of a rubber material, a foaming material, or a resin material.

8. The manufacturing device for the peeling member according to claim 7 , wherein the hardness of the roller body is set in a range between the Shore A10 hardness and the Shore A90 hardness.
