Abstract

For copying/printing machines, continuous Teflon belts, which may consist of either pure or impregnated Teflon, are suggested to hold the copy or print against the high temperature fuser roll. This prevents shear stress in the paper since the teflon belts move in synchronism with the heated surface of the fuser roll. As a result, paper distorting/cockling is reduced or eliminated.

For copying/printing machines, continuous Teflon belts, which may consist of either pure or impregnated Teflon, are suggested to hold the copy or print against the high temperature fuser roll. This prevents shear stress in the paper since the teflon belts move in synchronism with the heated surface of the fuser roll. As a result, paper distorting/cockling is reduced or eliminated.

Further, the Teflon belts provide low friction normal force to the paper feed rolls. This avoids the need to use roll pairs for this purpose, reducing costs.

The mass of the Teflon belts is determined for optimum removal of excess heat energy from the fuser roll, i.e., the mass of the Teflon belts is chosen so that the heat dissipation of the belts is the same as that of the paper being fused.

While Teflon has been suggested as the belt material, other suitable belt materials for this purpose may be envisioned.
