摘要:
Multiple layer fuser belts having a woven fabric layer and a high conformability, low surface energy elastic layer. The fabric layer is formed from high modulus, high temperature fibers that are woven together at acute angles to the circumference of the belt fibers. The fabric layer forms a substrate with preferential stretching along the circumference of the fuser belt. The elastic layer is bonded to the fabric layer and is made from a highly conformable, low durometer material having a low surface tension. When the fuser belt is partially wrapped around a driven roller so as to form a nip with a pressure roller the fuser belt stretches in the direction of belt motion. As the fuser belt passes through the nip the fuser belt contracts, releasing surface tension and thus reduces sticking between the fuser belt and fused toner.

Multiple layer fuser belts having a rigid or semi-rigid substrate layer and a high conformability, low surface energy elastic layer. The substrate layer is formed from long-life material such as polyimide. Apertures, beneficially elongated diamonds, are cut into the substrate layer such that the substrate layer can stretch slightly along the circumference of the fuser belt. The elastic layer is bonded to the substrate layer and is made from a highly conformable, low durometer material having a low surface energy. When the fuser belt is partially wrapped around a driven roller so as to form a nip with a pressure roller the fuser belt stretches in the direction of belt motion. As the fuser belt passes through the nip the fuser belt contracts, releasing surface strain, and thus reduces sticking between the fuser belt and fused toner.

Puzzle-cut imageable seam intermediate transfer belts having a large seam surface area, and marking machines that use such imageable seam intermediate transfer belts. A belt is formed from a semiconductive substrate having a puzzle-cut first end and a puzzle-cut second end that are mated to form a seam. The first end includes a first tongue and the second end includes a second tongue that form a rabbeted joint such that the outer surface of the belt is substantially smooth across the seam. An adhesive is disposed over the rabbeted joint. The tongues may include mechanical locking features, such a protrusion and a channel, that mate. The mechanical locking features may be continuous along the seam.

There is disclosed a belt assembly including: (a) an endless belt capable of repeated cycling over rollers having a first side edge and a second side edge and defining a center region between two side regions, wherein a low friction composition comprised of a fluoropolymer covers a portion of the length of the first side edge; and (b) a belt guide apparatus which contacts the first side edge during cycling of the belt to position the belt on the rollers, wherein the low friction composition reduces the wear of the belt at the first side edge.

An endless flexible seamed belt formed by joining two ends of material from which the belt is fabricated each end of which has a plurality of mutually mating elements in a puzzle cut pattern which are in interlocking relationship to prevent separation of the ends and which form a seam when joined mechanically to enable the flexible belt to essentially function as an endless belt having a substantially uniform thickness, said seam having voids between mutually mating elements at least partially filled with a seam strength enhancing material which is chemically and physically compatible with the material from which the belt is fabricated and which substance applied as a strip or on a strip over the seam and is bound to said belt material, said bond having been formed by the application of heat and/or pressure to a strip of said compatible placed material on at least one side of the seam at least substantially covering the seam. The strip may include a substrate with a coating of the compatible material which is removed after the bond is formed.

An endless flexible seamed belt with a mechanically invisible seam and substantially equivalent in performance to a seamless belt is formed by joining two ends of material from which the belt is fabricated each end of which has a plurality of mutually mating elements in a puzzle cut pattern which are in interlocking relationship in at least one plane and which when joined mechanically enable the flexible belt to essentially function as an endless belt having a substantially uniform thickness.
摘要:
A non-contacting electrostatic measurement apparatus including a vibratory element and an electrode, affixed to the vibratory element, suitable for sensing a capacitive coupling relationship with an electrostatic field to produce a signal indicative of the magnitude of the electrostatic field. The signal is transmitted to signal processing circuitry via conductive fibers so as to impose little mechanical loading on the vibrating electrode. The electrode may be either unshielded, for an electrically floating electrostatic voltmeter, or shielded, for an electrostatic voltmeter employing electrically grounded components.

A seamless intermediate transfer member has a reinforcing member in an endless configuration, a filler material such as a polymer and electrical property regulating material to regulate the electrical properties such as surface and bulk resistivity, dielectric constant and charge dissipation. The seamless intermediate transfer member also has good mechanical properties. The reinforcing member can be prepared by any suitable method such as by weaving. Filler material and electrical regulating material can be applied on, around or embedded into the reinforcing member. The member can be employed in an electrostatographic imaging system with more than one toner imaging station. The member can pick up a separate image from each individual imaging station and transfer the combined image to a suitable substrate. The seamless intermediate transfer member is capable of dissipating charge between toner imaging stations, achieving good transfer efficiencies and has a non-stretch characteristic to attain good registration of a toner image.
