摘要:
A system for manufacturing large quantities of seamed belts for printing systems with controlled imageable seams, which belts require a defined circumference and width, from suitable belt material in a large roll thereof, by feeding a continuous web of that belt material from the roll in (or cut to) a width that is at least as wide as the defined circumference of the finished seamed belt into a seam cutting station, where the opposing side edges of the continuous web of belt material are cut as they move through the seam cutting station into opposing seam-forming mating edge patterns, preferably mating puzzle-cut patterns cut by small movement laser beams on each side of the moving web. The moving web is then wrapped over a mandrel surface so that the opposing side edges of the web are brought together while said continuous web of belt material is moving, mating the opposing edge patterns together to form a belt seam in a moving tube of the web material, the belt seam is adhesively sealed, and then increments of this moving tube are intermittently transversely cut off to the selected width of the finished seamed belt.

A method of making a connector by applying a focused beam from a laser to a polymer matrix containing plurality of conductive fibers in parallel. The laser is applied at one end of the matrix to volatilize the matrix so as to expose the plurality of conductive fibers to provide a laser fibrillated brush-like structure to define an electrically contacting surface.

Static eliminator device includes a nonmetallic pultruded composite member having a plurality of conductive carbon fibers provided within a polymer matrix of thermosetting resin, wherein the plurality of carbon fibers are oriented within the polymer matrix in a longitudinal direction of the pultruded composite member and extend continuously therethrough. The pultruded composite member has at least one laser fibrillated end including a brush-like structure of densely distributed filament contacts formed from an exposed length of the carbon fibers for contact with the surface. The brush-like structure has either a straight edge configuration or a shaped configuration. The static eliminator device may include a base member for holding the pultruded composite member, wherein the base member electrically communicates with the plurality of conductive fibers to permit the electrical charge to pass therefrom. The static eliminator device utilizes a plurality of the pultruded composite members attached to the base member, each having a rod shape, or a single pultruded composite member having a planar shape. Alternatively, the static eliminator device may essentially be of single piece construction, wherein the pultruded composite member is planar in shape.

摘要:
A contact for use in contacting a moving photoreceptor surface, is formed from a structure (preferably a pultrusion) including a plurality of continuous strand fibers of high electrical resistance, and a thermally stable insulating component between the resistive fibers. The resistive fibers are configured to form a brush extending from the insulating component for contact with the photoreceptor surface. The resistance of the fibers is sufficiently high to reduce leakage of surface charges away from the photoreceptor and to provide a high resistance between adjacent fibers. The insulating component, which serves to interface the carbon filaments from each other and from a host polymer may comprise an organic compound, such as a polyimide composition, or may comprise an inorganic compound such as Al.sub.2 O.sub.3 or water glass, and is thermally stable below about 1000.degree. C. The host polymer, on the other hand volatilizes rapidly and cleanly upon direct exposure to laser energy.

A three dimensional electrical component having a first side and a second side formed from an electrically insulating polymer matrix capable of heat conversion to an electrically conducting polymer matrix has at least one passageway from the first side to the second side having a tapered wall slope configuration from the first side to the second side with constantly changing cross section of the passageway from the first side through the passageway to the second side, an electrically conducting path between the first side and the second side formed by the in situ heat conversion of the walls of the passageway in the electrically insulating polymer matrix. In a preferred embodiment the electrically conducting path is formed by directing a laser beam to the walls of the passageway to heat the insulating polymer matrix to a temperature sufficient to convert it to an electrically conducting polymer matrix.
