摘要:
An ultrasonic welding member for use in welding seamed flexible belts to produce smoother seams having reduced seam thickness. The ultrasonic welding member has a unique configuration, that includes an increased tip surface formed in such a manner that more energy from the horn is dispersed over the seam overlap region for a longer duration of time to produce a smoother and thinner weld.
摘要:
A weldable intermediate transfer belt having a substrate with a homogeneous composition of polyaniline in an amount of from about 2 to about 25 percent by weight of total solids, and a thermoplastic polyimide in an amount of from about 75 to about 98 percent by weight of total solids, and the polyaniline has a particle size of from about 0.5 to about 5.0 microns, and an apparatus for forming images on a recording medium and incorporating the intermediate transfer belt.
摘要:
A process for providing an improved imaging member belt having a welded seam which exhibits greater resistance to dynamic fatigue induced seam cracking and delamination. An apparatus for achieving stress relaxation and eliminating protrusions in the seam region is also disclosed.
摘要:
An image forming apparatus having an improved intermediate transfer belt, and processes for making the same. More specifically, there is provided an intermediate transfer belt having one or more steering ribs formed into the belt such that a separate steering rib need not be employed.

摘要:
Multilayered web stock is directed toward a curved surface and at least one layer of the web stock is heated to a temperature above a glass transition temperature of the at least one layer of the web stock. The heating can occur just before or upon engaging the curved surface. The temperature of the at least one layer remains above the glass transition temperature while engaging the curved surface, allowing reshaping and/or realignment of the at least one layer relative to other layers of the web stock according to conformance to the curved surface. The web stock is cooled before it disengages from the curved surface. The heating can be done with a high power infrared lamp focused into a line across the web stock, and the cooling can be done with a cooled fluid jet. Additionally, a preheater can be employed, and a supplemental cooler can be used.
摘要:
A welded intermediate transfer belt and process for making the same having a substrate made primarily of at least one polyimide polymer. The weld may be ultrasonically or otherwise welded and may have favorable properties such as relatively thin seam thickness and small weld steps. The weld may be overlapped or miter cut.
