摘要:
A novel method and apparatus for producing an endless flexible seamed belt using templates is disclosed. A first form of the template is a mask template with a template aperture in the form of a puzzle cut pattern to be used in combination with an excimer laser. The template is placed between the excimer laser source and the belt material to be cut. As the excimer laser traverses the width of the belt, the laser forms a puzzle cut pattern on the belt. A second form of the template is a punch and die having patterned edges in the form of a puzzle cut pattern with extremely small nodes and kerfs. The cutting tolerances of the patterned edges make it necessary to fix the punch with respect to the die so that there is no misalignment of the punch and die between cutting operations. This is accomplished by resiliently fixing the punch to the die, rather than having the punch attached to the force generating assembly as in normal punch and die assemblies. Belt material is positioned between a stock gap between the punch and die and the force generating assembly is activated to provide the cutting force. Once the belt material is cut, the cutting force is removed and the force generating assembly returns to its retracted position. Both types of templates result in very clean cuts without deformation or distortion.
摘要:
The present invention relates to an electrical component, which has an electrically conductive composition that is stable at high temperatures, and includes a partially pyrolized carbon based powder filler and a host matrix. The present invention also relates to an electrophotographic system which further is stable at conventional ambient environmental use conditions, such as different humidity levels and/or ambient temperature ranges.

Imageable seamed intermediate transfer belts having a large seam surface area, and marking machines that use such imageable seamed intermediate transfer belts. The seamed intermediate transfer belt having an inner surface and an outer surface having predefine surface properties for the purpose of imaging. A belt is formed from a semiconductive substrate having a first end and a second end that are mated to form a seam. An adhesive is disposed over the joint whereupon joint can be burnished or overcoated with a material that substantially imitate predefined surface properties of the belt.

A seamed flexible belt having a substrate and a seam having interlocking seam members, wherein the interlocking seam members are held together by an adhesive having a polymer and plasticizer other than bis(dihydroxy diethylamino) triphenyl methane, bis(diethylamino) triphenyl methane, or dihydroxy tetraphenyl biphenylene diamine, for use in electrostatographic, contact electrostatic, digital and other like machines.
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.
