Abstract
A device for tensioning a data carrier which is moved by feed tractors, such as a paper sheet moving past a printing station in a non-mechanical printer or copier in which the feed tractors consist of a toothed belt entrained about pairs of wheels, the teeth of the belt engaging perforations in the side margins of the data carrier, has a cam mounted on a shaft between the wheels in a feed tractor. The wheels are mounted on a guide block having a bearing element which acts as a cam follower so that by rotating the cam the wheels are synchronously displaced so as to suitably tension the data carrier in the printing station.
