<p>A system for separating one surface, preferably a web, from another surface to enable a bead of accumulated material built up at the line of contact between the two surfaces to pass therebetween. During the separation period, the advancing velocity of at least one surface is reduced so that at least one surface is advanced at a slower rate that its rate prior to separation, or stopped. In a preferred embodiment, the system is employed in photoelectrophoretic imaging to bypass a bead of imaging suspension built up at the imaging nip during separation of two webs immediately after completion of imaging to thereby permit dissipation or passage of the liquid bead. During the separation period, the surface, preferably a web, which does not carry the desired image, is advance at a slower rate than its prior rate and slower than the other surface, or stopped.</p> |
