摘要:
An adhesive having a resin selected from polyvinyl butyral resins, phenolic resins, epoxy resins, and mixtures thereof, and at least one type of filler such as a carbon filler, for use in seaming components useful in electrostatographic, contact electrostatic, digital and other like machines.
摘要:
A process for seaming seamed component for use in seaming members useful in electrostatographic, contact electrostatic, digital and other like machines, including: a) compounding an adhesive; b) forming the adhesive in contact with a first side of the seam and the mutually mating members; c) contacting the adhesive and first side of the seam to a first heated clamp; d) contacting the second side of the seam to a second heated clamp; e) subjecting the adhesive in contact with the mutually mating members to a first cure at a first temperature to form a cured adhesive; and f) subjecting the cured adhesive to a second cure at a second temperature to form a dual-cured adhesive, wherein the second temperature is higher than the first temperature.

摘要:
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.
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.

摘要:
Seamed belts having puzzle-cut seam with edges that are themselves puzzle-cut: puzzle-cut on puzzle-cut seamed belts. Such belts beneficially may take the form of imageable seam intermediate transfer belts such as those used in marking machines. Belts are formed from a substrate having a puzzle-cut first end and a puzzle-cut second end that interlock to form a seam. That first end includes puzzle-cut tabs that have puzzle-cut edges and the second end includes puzzle-cut tabs that also have puzzle-cut edges. The first end and the second end interlock such that the puzzle tabs and the puzzle-cut edges mate to form the seam. Beneficially an adhesive is disposed over the seam. If the seamed belt is an imageable seam intermediate transfer belt the substrate is beneficially semiconductive.
