A method of treating a preformed flexible imaging belt including providing a rigid cylindrical support drum having a precisely predetermined outer circumference, a first end and a second end, providing a preformed flexible electrostatographic imaging belt, circumferentially expanding the belt with a flowing fluid under pressure until the circumference of the inner surface of the belt adjacent the first end of the drum is stretched to a new dimension of at least about 0. 1 percent greater than the outer circumference of the rigid support drum while maintaining the belt below the elastic limit of the belt to smooth out physical defects, sliding the belt onto the drum from the first end toward the second end until substantially all of the belt encircles the outer surface of the drum, terminating the flow of the flowing fluid to allow the belt to contract onto the outer surface of the support drum, heating the belt to a treatment temperature of between about the glass transition temperature and about 10. degree. C. above the glass transition temperature of the substrate or the imaging layer, the treatment temperature being the higher of these two glass transition temperatures, until the belt relaxes onto the outer circumference of the rigid drum and is substantially free of any tendency to contract back to the original circumference of the inner exposed surface prior to circumferentially expanding the belt, cooling the belt to ambient room temperature, and removing the belt from the drum, the belt having a new inner circumference substantially identical to the precisely predetermined outer circumference of the rigid cylindrical support drum.

A process including providing at least two support members maintained at a predetermined distance from each other, encircling the support members with at least one loosely hanging preformed flexible seamless carrier support sleeve having a predetermined outer circumference, encircling the seamless carrier support sleeve with a flexible belt having an inner circumference substantially same as or less than the predetermined outer circumference of the seamless carrier support sleeve, and increasing the distance between the support members to stretch the flexible belt, the size of the inner circumference of the stretched flexible belt being substantially equal to the outer circumference of the seamless carrier support sleeve after stretching the flexible belt. The resulting flexible belt assembly fabricated by this process may be utilized in various systems including electrostatographic imaging systems.
