ABSTRACT:
A cable tensioning system for use in an electrostatic transfer apparatus is provided to permit a developed image to be transferred from a first surface to a second receiving surface so that the dimensional integrity of the transferred image is ensured. The cable tensioning system is connected to a web or belt material that receives the transferred image as an intermediate transfer surface by a transfer roller traversing the length of the web bringing one surface of the web into close proximity with the developed image to permit it to be transferred to the web. The tensioning system prevents the web from becoming slack.
