12 JCW/3616 Abstract of the Disclosure Web Tensioning a Device A web tensioning device comprises a reservoir (4) into which a loop (26) of the web (24) extends. The reservoir has a width which generally only slightly exceeds that of the web, and a variable pressure drop is established across the loop in the reservoir by means of a fan. Side ports (16;16A) allow a restricted air flow from one side of the loop to the other. The air flow may vary according to the position of the loop. In this way the pressure drop across the loop, and hence the tension in the web, varies with the position of the loop in the reservoir. The device is capable of maintaining a web at a predetermined tension or within a predetermined range of tensions and responds rapidly to external influences on tension, e.g. reversal of drive to the web.
