Packaging apparatus is provided for packaging a flexible photoconductive belt loop to prevent light from shocking the flexible photoconductive belt loop during shipping and during loading into an image reproduction machine. The packaging apparatus includes (a) a cut sheet of light occluding and protective flexible member for wrapping over the flexible photoconductive belt loop. The cut sheet has a length L2 including a first end, a second end, and (iv) at least one loop tacking aperture formed through a second end portion thereof. The packaging apparatus also includes a first adhesive tape member applied over the second end portion, through the at least one loop tacking aperture, and onto a first end portion. The packaging apparatus further includes a plurality of packaging cores, and a second adhesive tape member applied over the second end and over a portion of the main body portion.
摘要:
A process including providing at least a flexible substrate layer having a first major surface on one side and a second major surface on a second side opposite the first major surface, the first major surface being an exposed surface, applying a coating of an anticurl backing layer dispersion on the first major surface of the substrate layer, the dispersion comprising a volatile carrier liquid, a film forming polymer dissolved in the volatile carrier liquid, solid organic particles dispersed in the volatile carrier liquid, and an organic additive dissolved in the volatile carrier liquid, the organic additive represented by the structural formula: wherein m is a number from 1 to 99, n is a number from 1 to 99, p is an integer between 1 and 10, f is an integer between 1 and 8, and I is an integer between 10 and 500, and drying the coating to remove the volatile carrier and form a dried anticurl backing layer. An electrostatographic imaging member containing this anticurl backing layer is also described.
摘要:
A process for treating a seamed flexible electrostatographic imaging belt including providing an imaging belt including at least one layer including a thermoplastic polymer matrix and a seam extending from one edge of the belt to the other, providing an elongated support member having a arcuate supporting surface and mass, the arcuate surface having at least a substantially semicircular cross section having a radius of curvature of between about 9.5 millimeters and about 50 millimeters, supporting the seam on the arcuate surface with the region of the belt adjacent each side of the seam conforming to the arcuate supporting surface of the support member with a wrap angle at least sufficiently enough to provide arcuate support for the seam area, traversing the seam from one edge of the belt to the other with infrared rays from a tungsten halogen quartz bulb focused with a reflector having a hemiellipsoid shape to form a heated substantially circular spot straddling the seam during traverse, the spot having a diameter of between about 3 millimeters and about 25 millimeters, without exceeding the breadth of supported arcuate seam area, to substantially instantaneously heat the thermoplastic polymer matrix in the seam and the region of the belt adjacent each side of the seam directly under the heating spot to at least the glass transition temperature of the polymer matrix without significantly heating the support member, and rapidly quenching the seam by thermal conduction of heat from the seam to the mass of the support member to a temperature below the glass transition temperature of the polymer matrix while the region of the belt adjacent each side of the seam conforms to the arcuate supporting surface of the support member. Apparatus for carrying out this process is also disclosed.
摘要:
A cast-in reflective timing patch for a belt such as an intermediate transfer belt of a printing device. The timing patch is formed during manufacturing of the belt. As such, the presence, quality, location, and alignment of the timing patch is fixed and inspection and monitoring of the timing patch is no longer required.

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:
The presently disclosed embodiments relate in general to electrophotographic imaging members, such as layered photoreceptor structures, and processes for making and using the same. More particularly, the embodiments pertain to the development of a structurally simplified flexible electrophotographic imaging member without the need of an anticurl back coating layer and a post treatment process for effecting the imaging member service life extension in the field.
