摘要:
A method and apparatus for drying or curing rigid cylindrical and flexible belt substrates includes: a curing chamber defining a central axis; a support structure selectively receivable within the curing chamber and including a support for at least one substrate along the central axis which rotates the at least one substrate about the central axis; a curing mechanism surrounding the at least one substrate within the curing chamber for expelling temperature controlled low velocity air toward the at least one substrate as the at least one substrate rotates about the central axis without axial movement relative to the curing chamber; and inductive coils surrounding at least a portion of the at least one substrate within the curing chamber for indirectly heating the at least one substrate. Preferably, the at least one substrate is dried/cured by combination of indirect RF induction heating at the same time or prior to low velocity air impingement. By varying the frequency, power, coil diameter and spacing, heatup rates and temperatures can be very closely controlled and very rapid heatup rates can be achieved.

摘要:
A method of holding and transporting a hollow flexible belt throughout a coating process. The method includes placing an expandable insert into the hollow portion of a seamless flexible belt, and expanding the insert until it forms a chucking device with a protrusion on at least one end. A mechanical handling device is then attached to the protrusion, and will be used to move the chuck and the belt through the dipping process, as materials needed to produce a photosensitive device are deposited onto the surface of the belt, allowing it to be transformed into an organic photoreceptor. The chucking device and flexible belt are then removed from the mechanical handling device, the belt is cut to the desired width, and the chuck is removed from the inside of the photoreceptor.

A laser ablation apparatus includes a nozzle, disposed through a housing, wherein the nozzle has: (i) a nozzle housing comprised of a bottom surface; (ii) a first orifice defined by the bottom surface; (iii) a second orifice defined by the bottom surface; (iv) a first passageway defined by the nozzle housing in communication with the first orifice; and (v) a second passageway defined by the nozzle housing in communication with the second orifice, wherein the portion of the second passageway adjacent the second orifice forms an angle .theta..sub.3 with the portion of the first passageway adjacent the first orifice, wherein the angle .theta..sub.3 is effective for directing a first fluid stream through the second orifice at the surface of the enclosed substrate portion to facilitate removal of the coating in the form of coating debris during or subsequent to exposure of the coating of an enclosed substrate portion to high energy radiation. A high energy radiation generating apparatus and a first fluid stream generating apparatus are coupled to the nozzle. A second fluid stream nozzle is disposed in a direction for directing a second fluid stream against the first fluid stream to keep coating debris inside the housing. Exhausting apparatus is coupled to the housing.
